PART I

Item 1. Business.

National Housing Partnership Realty Fund I (A Maryland Limited Partnership) (the "Partnership" or the "Registrant") was formed under the Maryland Revised Uniform Limited Partnership Act as of October 21, 1983. On May 25, 1984, the Partnership commenced offering 20,000 limited partnership interests, at a price of $1,000 per interest, through a public offering registered with the Securities and Exchange Commission (the "Offering"). The Offering was terminated on November 29, 1984, with subscriptions for 11,519 limited partnership interests.

The National Housing Partnership, a District of Columbia limited partnership ("NHP" or the "General Partner"), is the general partner of the Partnership. The General Partner is a subsidiary of Apartment Investment and Management Company (“AIMCO”), a publicly traded real estate investment trust.

The Partnership's business is to hold limited partnership interests in limited partnerships which own and operate multi-family rental housing properties which receive one or more forms of assistance from the Federal Government. The Partnership held interests in nine limited partnerships, seven of which sold their properties and two whose interests were foreclosed upon prior to 2009. At December 31, 2010, the Partnership continues to hold a limited partnership interest in one limited partnership (“Local Limited Partnership”), Hurbell IV Limited Partnership, which owns and operates one multi-family rental housing property (the “Property”). Subsequent to December 31, 2010, the Local Limited Partnership entered into a sale contract to sell its investment property, Talladega Downs to a third party for $700,000. The sale is anticipated to close during May 2011. Assuming such sale occurs, the Partnership does not anticipate that the Local Limited Partnership will have any excess funds, after payment of its liabilities and liquidating its operations, to distribute to its partners. The Partnership has no remaining investment balance in the Local Limited Partnership at December 31, 2010 and 2009.

The Partnership acquired an interest in the Local Limited Partnership from the seller who originally developed the Property. NHP is the general partner of the remaining Local Limited Partnership and the Partnership is the principal limited partner. As a limited partner, the Partnership's liability for obligations of the Local Limited Partnership is limited to its investment, and the Partnership does not exercise control over the activities of the Local Limited Partnership in accordance with the partnership agreement.See “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations” for information relating to the Partnership’s rights and obligations to make additional contributions or loans to the Local Limited Partnership.

The Partnership does not have any employees. Services are performed for the Partnership by the General Partner and agents retained by it.

The following is a schedule of the remaining Property owned by the Local Limited Partnership in which the Partnership is a limited partner:

Although Hurbell IV Limited Partnership owns an apartment complex which must compete with other apartment complexes for tenants, government mortgage interest and rent subsidies make it possible to rent units to eligible tenants at below market rates. In general, this insulates the Property from market competition.

Regulation

General

Multifamily apartment properties are subject to various laws, ordinances and regulations, including regulations relating to recreational facilities such as swimming pools, activity centers and other common areas. Changes in laws increasing the potential liability for environmental conditions existing on properties or increasing the restrictions on discharges or other conditions, as well as changes in laws effecting development, construction and safety requirements, may result in significant unanticipated expenditures, which would adversely affect the Partnership’s cash flow from operating activities. In addition, future enactment of rent control or rent stabilization laws or other laws regulating multi-family housing may reduce rental revenue or increase operating costs in particular markets.

Regulation of Affordable Housing

The Federal Housing Administration (FHA) has contracted with the subsidized rental project under Section 8 of Title II of the Housing and Community Development Act of 1974 to make housing assistance payments to the Local Limited Partnership on behalf of qualified tenants. The term of the agreement is one year with one year renewal options.

In 1997 and again in 1999, Congress enacted new ways to determine rent levels for properties receiving HUD’s rental assistance under Section 8 of the United States Housing Act of 1937, as amended, (“Section 8") after the expiration of their original Section 8 contracts. This legislation affects 100 units, or 100% of the units in which the Partnership had invested at December 31, 2010 and 2009. On October 27, 1997, the President signed into law the Multifamily Assisted Housing Reform and Affordability Act of 1997 (the “1997 Housing Act”). Under the 1997 Housing Act, certain properties assisted under expiring Section 8 contracts and which have been receiving rents deemed to be above comparable market levels for unassisted properties, and financed with HUD-insured mortgage loans, will have, upon the renewal or extension of Section 8 contracts, rents marked to market. This will be accomplished in various ways, the goal being to reduce Section 8 rents to comparable market levels, thereby reducing the federal Section 8 subsidy obligation, and (ideally) by simultaneously lowering, or eliminating, required debt service costs (and decreasing operating costs) as needed to ensure financial viability at the reduced rent levels. The program also incorporates a requirement to perform any repair or rehabilitation deemed necessary by depositing funds to cover the first twelve month's work, and making sufficient monthly reserve deposits to ensure work required in succeeding years. In 1999, Congress enacted legislation (the "1999 Housing Act") that expanded on and clarified the provisions of the 1997 Housing Act, including permitting properties whose Section 8 rents were below comparable market rents to increase their Section 8 rents to market.

The 1997 and 1999 Housing Acts (together, the “Housing Acts”) permit the retention of project based Section 8 contracts for most properties in rental markets with a limited supply of affordable housing or where the tenants are particularly vulnerable populations including the elderly, disabled or large families. In rental markets without a limited supply of affordable housing, the Housing Acts provide for phasing out project based subsidies, converting the assistance to tenant based assistance or vouchers. Under a tenant based system, rental vouchers would be issued to qualified tenants who then could elect to reside at properties of their choice, including the property in which they currently reside. Voucher rent levels are established by local housing authorities under guidelines set by HUD. While the Partnership does not expect the provisions of the Housing Acts to result in a significant number of tenants relocating from the property owned by the Local Limited Partnership, there can be no assurance that the legislation will not significantly and adversely affect the operations of the property of the Local Limited Partnership.

The following table indicates the year within which the Section 8 rent subsidy contract expires:

		Subsidized Units	Subsidized Units
		Expiring as a	Expiring as a
	Number of	Percentage of Total	Percentage of
	Units	Subsidized Units	Total Units

2011	100	100%	100%

All of the units (100 in total) receiving rent subsidies from Section 8 have their contracts expire during the year ending December 31, 2011.The Housing Acts provide for several options under which a Local Limited Partnership may elect, as appropriate, to renew its Section 8 contracts: (1) marking rents up to the comparable market rent, if current rents are below market; (2) renewing rents at the current level, if the level does not exceed comparable market rents, and receiving an operating cost adjustment factor (an “OCAF”) or a budget based rent increase, as long as the rents do not exceed comparable market rents; (3) marking rents down to comparable market rents; (4) marking their rents down to an “exception rent” level, when comparable market rents would be too low to permit continued operation of the property under the Section 8 program, even with full debt restructuring; or (5) opting out of the Section 8 program. For properties assisted by Section 8, but not subject to these provisions (including, but not limited to, properties which do not have underlying HUD insured mortgages, or which have been financed through certain state housing finance agency or bond-financed mortgage programs), rents will be continued at current levels, plus an OCAF or (in some instances) a budget based rent increase. In addition, properties can opt out of the Section 8 program only if very strict notice requirements have been met, including a requirement that HUD, the tenants, and the local governing body, be given twelve months notice of a Local Limited Partnership’s intention to opt out of the program prior to contract termination.

Each of the options requires an application to HUD, and, to a greater or lesser extent, the fulfillment of certain procedural submission requirements and financial requirements, which must be weighed in connection with the determination of which option to select.

The Section 8 requirements are separate from the requirements governing the underlying HUD-insured mortgage loans, and any other HUD, state or local requirements, all of which must be fulfilled, irrespective of the option chosen with regard to the continuation of Section 8 participation.

The Local Limited Partnership recorded approximately $475,000 of its revenues during 2010 from HUD under the terms of one or more HAP contracts which provide for rental assistance to the Local Limited Partnership on behalf of low-income tenants who meet certain qualifications. The Local Limited Partnership's future intentions and potential future changes in HUD regulations and the appropriations of related funds are uncertain, and accordingly, it is not possible to determine the ultimate impact on the operations of the Local Limited Partnership. The current contract expires on February 28, 2011 and subsequent to December 31, 2010 was renewed for an additional year beginning on March 1, 2011. Additionally, subsequent to December 31, 2010, the Local Limited Partnership entered into a contract to sell Talladega Downs to a third party for a sales price of $700,000. The sale is anticipated to close during May 2011.

HUD Approval and Enforcement

The property owned by the Local Limited Partnership is subject to regulations by HUD. Under its regulations, HUD reserves the right to approve the owner and the manager of HUD-insured and HUD-assisted properties, as well as their “principals” (e.g. general partners, stockholders with 10% or greater interest, officers and directors) in connection with the acquisition of a property, participation in HUD programs or the award of a management contract. This approval process is commonly referred to as “2530 Clearance.” HUD monitors the performance of properties with HUD-insured mortgage loans. HUD also monitors compliance with applicable regulations, and takes performance and compliance into account in approving the acquisition of management of HUD-assisted properties.

Laws Benefiting Disabled Persons

Under the Americans with Disabilities Act of 1990, or ADA, all places intended to be used by the public are required to meet certain Federal requirements related to access and use by disabled persons. Likewise, the Fair Housing Amendments Act of 1988, or FHAA, requires apartment properties first occupied after March 13, 1990 to be accessible to the handicapped. These and other Federal, state and local laws may require modifications to the Local Limited Partnership’s property, or restrict renovations of the property. Noncompliance with these laws could result in the imposition of fines or an award of damages to private litigants and also could result in an order to correct any non-complying feature, which could result in substantial capital expenditures. Although the General Partner believes that the Local Limited Partnership’s property is substantially in compliance with present requirements, the Local Limited Partnership may incur unanticipated expenses to comply with the ADA and the FHAA.

Environment

Various Federal, state and local laws subject property owners or operators to liability for the costs of removal or remediation of certain potentially hazardous materials present on a property, including lead-based paint, asbestos, polychlorinated biphenyls, petroleum-based fuels, and other miscellaneous materials. Such laws often impart liability without regard to whether the owner or operator knew of, or was responsible for, the release of such materials. The presence of, or failure to properly remediate, these materials may adversely affect occupancy at contaminated apartment communities and the Partnership’s ability to sell or borrow against contaminated properties. In addition to the costs associated with investigation and remediation actions brought by governmental agencies, the improper management of these materials on a property could result in claims by private plaintiffs for personal injury, disease, disability or other infirmities. Various laws also impose liability for the cost of removal or remediation of these materials or toxic substances at the disposal or treatment facility. Anyone who arranges for the disposal or treatment of these materials or toxic substances is potentially liable under such laws. These laws often impose liability whether or not the person arranging for the disposal ever owned or operated the disposal facility. In connection with the ownership or operation of its property, the Local Limited Partnership could potentially be responsible for environmental liabilities or costs associated with its property.

The General Partner believes that the property owned by the Partnership through the ownership of its limited partnership interest in a Local Limited Partnership is covered by adequate fire, flood and property insurance provided by reputable companies and with commercially reasonable deductibles and limits.

Item 2. Property.

See "Item 1. Business" for the real estate owned by the Partnership through the ownership of its limited partnership interest in a Local Limited Partnership.

Item 3. Legal Proceedings.

The Partnership is unaware of any pending or outstanding litigation involving it or the underlying investment property of the Local Limited Partnership in which the Partnership invests that are not of a routine nature arising in the ordinary course of business.

PART II

Item 5. Market for Registrant's Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities.

(a) Interests in the Partnership were sold through a public offering. There is no established market for resale of Partnership interests nor is a market expected to develop in the near future. Accordingly, an investor may be unable to sell or otherwise dispose of his or her interest in the Partnership.

(b) As of December 31, 2010, there were 920 registered holders of 10,963 limited partnership interests (in addition to 1133 Fifteenth Street Associates - See "Item 8. Financial Statements and Supplementary Data - Note 2"). In 2010 and 2009, the number of Limited Partnership Units decreased by 17 and 25, respectively, due to Limited Partners abandoning his or her units. In abandoning his or her Limited Partnership Unit(s), a Limited Partner relinquishes all rights, title and interest in the Partnership as of the date of abandonment.

Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations.

This item should be read in conjunction with the financial statements and other items contained elsewhere in this report.

Liquidity and Capital Resources

The property in which the Partnership has invested, through its investment in Hurbell IV Limited Partnership, receives one or more forms of assistance from the Federal Government. As a result, the Local Limited Partnership's ability to transfer funds to the Partnership in the form of cash distributions, loans or advances is generally restricted by these government assistance programs. The General Partner monitors developments in the area of legal and regulatory compliance.

The Partnership had cash and cash equivalents of approximately $4,000 and $7,000 at December 31, 2010 and 2009, respectively. The ability of the Partnership to meet its on-going cash requirements, in excess of cash on hand at December 31, 2010, is dependent on distributions from recurring operations received from the Local Limited Partnership and proceeds from the sale or refinancing of the underlying property. The Partnership’s only other form of liquidity are advances from its General Partner. AIMCO Properties, L.P., an affiliate of the General Partner, will evaluate lending the Partnership additional funds as such funds are needed, but is in no way legally obligated to make such advances.

Subsequent to December 31, 2010, the Local Limited Partnership entered into a sale contract to sell its investment property, Talladega Downs to a third party for $700,000. The sale is anticipated to close during May 2011. Assuming such sale occurs, the Partnership does not anticipate that the Local Limited Partnership will have any excess funds, after payment of its liabilities and liquidating its operations, to distribute to its partners.

During the years ended December 31, 2010 and 2009, AIMCO Properties, L.P., an affiliate of the General Partner advanced the Partnership approximately $45,000 and $50,000, respectively, to fund audit fees and operating expenses of the Partnership. The advances bear interest at the prime rate plus 2% (5.25% at December 31, 2010). Interest expense was approximately $4,000 and $1,000 for the years ended December 31, 2010 and 2009, respectively. At December 31, 2010 and 2009, there were outstanding advances and associated accrued interest of approximately $100,000 and $51,000, respectively. The Partnership may receive additional advances of funds from AIMCO Properties, L.P. although AIMCO Properties, L.P. is not obligated to provide such advances. For more information on AIMCO Properties, L.P., including copies of its audited balance sheet, please see its reports filed with the Securities and Exchange Commission.

At December 31, 2010 and 2009, the Partnership owed the General Partner approximately $23,000 and $18,000, respectively, for administrative and reporting services performed. As noted above, the property held by the Partnership’s remaining investment in a Local Limited Partnership is under contract to sell during May 2011. The Partnership does not anticipate that it will receive any funds from the sale. Accordingly, the Partnership does not anticipate that it will be able to pay the accrued administrative and reporting fees or the advances it owes at December 31, 2010 to its General Partner and affiliates.

Net cash used in operations for the year ended December 31, 2010 was approximately $48,000, compared to net cash used in operations of approximately $44,000 for the year ended December 31, 2009.

During the years ended December 31, 2010 and 2009, the Partnership made no advances for working capital purposes to the Local Limited Partnership. There were no amounts owed to the Partnership for working capital advances to the Local Limited Partnership at December 31, 2010 or 2009.

During the years ended December 31, 2010 and 2009, AIMCO Properties, L.P., an affiliate of the General Partner advanced approximately $45,000 and $89,000, respectively, to Hurbell IV Limited Partnership to fund operating expenses. Interest on the advances is charged at the prime rate plus 2% (5.25% at December 31, 2010). During the year ended December 31, 2009, Hurbell IV Limited Partnership repaid AIMCO Properties, L.P. approximately $3,000, which included approximately $2,000 of accrued interest. There were no repayments made during the year ended December 31, 2010. At December 31, 2010 and 2009, the balance owed to AIMCO Properties, L.P., an affiliate of the General Partner by the Local Limited Partnership was approximately $262,000 and $204,000, respectively, including accrued interest of approximately $43,000 and $30,000, respectively. The Local Limited Partnership may receive additional advances of funds from AIMCO Properties, L.P. although AIMCO Properties, L.P. is not obligated to provide such advances.

The Local Limited Partnership accrued annual partnership administration fees payable to the General Partner of approximately $7,000 for each of the years ended December 31, 2010 and 2009. Payments of these fees are made to the General Partner from surplus cash available for distribution to partners pursuant to HUD regulations or sale proceeds. No payments were made during the years ended December 31, 2010 and 2009. The accumulated fees owed to NHP by Hurbell IV Limited Partnership are approximately $110,000 and $103,000 at December 31, 2010 and 2009, respectively.

Distributions received in excess of investment in the Local Limited Partnership represent the Partnership's proportionate share of the excess cash available for distribution from the Local Limited Partnership. As a result of the use of the equity method of accounting for the Partnership's investment in the Local Limited Partnership, the investment carrying value for the Local Limited Partnership has been reduced to zero. Cash distributions received are recorded in revenues as distributions received in excess of investment in Local Limited Partnership. There were no distributions received from the Local Limited Partnership during the years ended December 31, 2010 and 2009. The receipt of distributions in future years is dependent on the operations of the underlying property of the Local Limited Partnership and the sale or refinancing of the underlying property. The receipt of which is unlikely as discussed above.

The Partnership made no distributions during the years ended December 31, 2010 and 2009.

As discussed in Note 3 to the financial statements included in “Item 8. Financial Statements and Supplementary Data”, Hurbell IV Limited Partnership executed certain notes payable as part of the acquisition of the property by the Local Limited Partnership. The notes are nonrecourse notes secured by both the Partnership's and NHP's interests in the Local Limited Partnership and are subordinated to the mortgage note on the property for as long as the mortgage note is insured by HUD. The notes were due November 9, 1999. The noteholders have not exercised any rights under the notes. The Local Limited Partnership has been advised by counsel that the notes are no longer enforceable due to the passage of the applicable statute of limitations. The Local Limited Partnership has also incurred recurring losses from operations and receives advances from its general partner to cover its operations. These conditions raise substantial doubt about the Local Limited Partnership’s and the Partnership’s ability to continue as a going concern. The financial statements do not include any adjustments to reflect the possible future effects of the recoverability and classification of assets or the amounts and classifications of liabilities that may result from the outcome of this uncertainty.

Results of Operations

At December 31, 2010 and 2009, the Partnership holds an interest in one Local Limited Partnership, which operates one rental housing property. Due to the use of the equity method of accounting as discussed in “Note 2 – Organization and Summary of Significant Accounting Policies” to the financial statements included in “Item 8. Financial Statements and Supplementary Data”, to the extent the Partnership still has a carrying basis in a Local Limited Partnership, results of operations will be impacted by the Partnership’s share of the profits or losses of the Local Limited Partnership. The investment balance in the Local Limited Partnership has been reduced to zero. As a result, the Partnership’s operations are no longer being affected by its share of the Local Limited Partnership’s operations.

The Partnership realized net losses of approximately$50,000 and $47,000 for the years ended December 31, 2010 and 2009, respectively. Net loss per Other Limited Partnership interest was $4.55 and $4.27 for the years ended December 31, 2010 and 2009, respectively.

The Partnership did not recognize approximately $100,000 and $162,000 of its allocated share of losses from Hurbell IV Limited Partnership for the years ended December 31, 2010 and 2009, respectively, as the Partnership's net carrying basis in this Local Limited Partnership had been reduced to zero. As of December 31, 2010 and 2009, the Partnership has not recognized approximately $2,132,000 and $2,032,000, respectively, of its allocated share of cumulative losses from Hurbell IV Limited Partnership in which its investment is zero.

Off-Balance Sheet Arrangements

The Partnership owns a limited partnership interest in an unconsolidated Local Limited Partnership, in which the Partnership’s ownership percentage is 99%. However, based on the provisions of the relevant partnership agreement, the Partnership, as a limited partner, does not have control or a contractual relationship with the Local Limited Partnership that would require or allow for consolidation under accounting principles generally accepted in the United States (see “Note 2 – Organization and Summary of Significant Accounting Policies” of the financial statements in “Item 8. Financial Statements and Supplementary Data”). There are no lines of credit, side agreements or any other derivative financial instruments between the Local Limited Partnership and the Partnership. Accordingly the Partnership’s maximum risk of loss related to this unconsolidated Local Limited Partnership is limited to the recorded investment in and receivables from the Local Limited Partnership. See “Note 3 – Investments In and Advances to Local Limited Partnership” of the financial statements in “Item 8. Financial Statements and Supplementary Data” for additional information about the Partnership’s investment in the unconsolidated Local Limited Partnership.

Variable Interest Entities

The Partnership consolidates any variable interest entities in which the Partnership holds a variable interest and is the primary beneficiary.Generally, a variable interest entity, or VIE, is an entity with one or more of the following characteristics: (a) the total equity investment at risk is not sufficient to permit the entity to finance its activities without additional subordinated financial support; (b) as a group the holders of the equity investment at risk lack (i) the ability to make decisions about an entity’s activities through voting or similar rights, (ii) the obligation to absorb the expected losses of the entity, or (iii) the right to receive the expected residual returns of the entity; or (c) the equity investors have voting rights that are not proportional to their economic interests and substantially all of the entity’s activities either involve, or are conducted on behalf of, an investor that has disproportionately few voting rights. The primary beneficiary of a VIE is generally the entity that has (a) the power to direct the activities of the VIE that most significantly impact the VIE’s economic performance, and (b) the obligation to absorb losses or the right to receive benefits that could potentially be significant to the VIE.

In determining whether it is the primary beneficiary of a VIE, the Partnership considers qualitative and quantitative factors, including, but not limited to: which activities most significantly impact the VIE’s economic performance and which party controls such activities; the amount and characteristics of the Partnership’s investment; the obligation or likelihood for the Partnership or other investors to provide financial support; and the similarity with and significance to the business activities of the Partnership and the other investors. Significant judgments related to these determinations include estimates about the current and future fair values and performance of real estate held by these VIEs and general market conditions.

At December 31, 2010 and 2009, the Partnership holds a variable interest in one VIE for which the Partnership is not the primary beneficiary. The Partnership has concluded, based on its qualitative consideration of the partnership agreement, the partnership structure and the role of the general partner in the Local Limited Partnership, that the general partner of the Local Limited Partnership is the primary beneficiary of the respective Local Limited Partnership. In making this determination, the Partnership considered the following factors:

· the general partner conducts and manages the business of the Local Limited Partnership;

· the general partner has the responsibility for and sole discretion over selecting a property management agent for the Local Limited Partnership’s underlying real estate property;

· the general partner is responsible for approving operating and capital budgets for the property owned by the Local Limited Partnership;

· the general partner is obligated to fund any recourse obligations of the Local Limited Partnership;

· the general partner is authorized to borrow funds on behalf of the Local Limited Partnership; and

· the Partnership, as a limited partner in the Local Limited Partnership, does not have the ability to direct or otherwise significantly influence the activities of the Local Limited Partnership that most significantly impact such entity’s economic performance.

The one VIE consists of a Local Limited Partnership that is directly engaged in the ownership and management of one apartment property with a total of 100 units. The Partnership is involved with this VIE as a non-controlling limited partner equity holder. The Partnership’s maximum exposure to loss as a result of its involvement with the unconsolidated VIE is limited to the Partnership’s recorded investment in and receivables from this VIE, which were zero at both December 31, 2010 and 2009. The Partnership may be subject to additional losses to the extent of any financial support that the Partnership voluntarily provides in the future.

Report of Independent Registered Public Accounting Firm

The Partners

National Housing Partnership Realty Fund I

We have audited the accompanying balance sheets of National Housing Partnership Realty Fund I (the “Partnership”) as of December 31, 2010 and 2009, and the related statements of operations, changes in partners’(deficiency)capital, and cash flows for each of the two years in the period ended December 31, 2010. These financial statements are the responsibility of the Partnership’s management. Our responsibility is to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. We were not engaged to perform an audit of the Partnership’s internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Partnership’s internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the financial position of National Housing Partnership Realty Fund I at December 31, 2010 and 2009, and the results of its operations and its cash flows for each of the two years in the period ended December 31, 2010 in conformity with U.S. generally accepted accounting principles.

The accompanying financial statements have been prepared assuming that the Partnership will continue as a going concern. As more fully described in Note 1 to the financial statements, the due date of the Local Limited Partnership’s note payable has expired. Continuation of the Partnership’s operations in its present form is dependent on the Local Limited Partnership’s ability to extend the maturity date of the note or to repay or to refinance the note. These conditions raise substantial doubt about the Local Limited Partnership’s and the Partnership’s ability to continue as a going concern. The financial statements do not include any adjustments to reflect the possible future effects of the recoverability and classification of assets or the amounts and classification of liabilities that may result from the outcome of this uncertainty.

NOTES TO FINANCIAL STATEMENTS

1. GOING CONCERN

The accompanying financial statements have been prepared assuming National Housing Partnership Realty Fund I (the “Partnership” or the “Registrant”) will continue as a going concern. As discussed in Note 3, Hurbell IV Limited Partnership (the “Local Limited Partnership”) previously executed certain notes payable which were due November 9, 1999, however, the Local Limited Partnership has been advised by counsel that these notes are no longer enforceable due to passage of the applicable statute of limitations.

The Local Limited Partnership has also incurred recurring losses from operations and receives advances from its general partner to cover its operations. These conditions raise substantial doubt about the Local Limited Partnership’s and the Partnership’s ability to continue as a going concern. The financial statements do not include any adjustments to reflect the possible future effects on the recoverability and classification of assets or the amounts and classification of liabilities that may result from the outcome of this uncertainty.

2. ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Organization

National Housing Partnership Realty Fund I is a limited partnership organized under the laws of the State of Maryland under the Maryland Revised Uniform Limited Partnership Act on October 21, 1983. The Partnership was formed for the purpose of raising capital by offering and selling limited partnership interests and then investing in limited partnerships ("Local Limited Partnerships"), each of which owns and operates an existing rental housing project which is financed and/or operated with one or more forms of rental assistance or financial assistance from the U.S. Department of Housing and Urban Development ("HUD").

The National Housing Partnership, a District of Columbia limited partnership ("NHP" or the "General Partner"), raised capital for the Partnership by offering and selling to additional limited partners 11,519 investment units at a price of $1,000 per unit. Apartment Investment and Management Company ("AIMCO"), a publicly traded real estate investment trust, and its affiliates ultimately control the General Partner. The Original Limited Partner of the Partnership is 1133 Fifteenth Street Associates, whose limited partners were key employees of the general partner of NHP at the time the Partnership was formed. The general partner of 1133 Fifteenth Street Associates is NHP.

Subsequent Events

The Partnership’s management evaluated subsequent events through the time this Annual Report on Form 10-K was filed.

Significant Accounting Policies

The financial statements of the Partnership are prepared on the accrual basis of accounting. Direct costs of acquisition, including acquisition fees and reimbursable acquisition expenses paid to the General Partner, have been capitalized as an investment in the Local Limited Partnership. Other fees and expenditures of the Partnership are recognized as expenses in the period the related services are performed.

The Partnership’s investment in the Local Limited Partnership is accounted for using the equity method and thus is carried at cost plus the Partnership’s share of the Local Limited Partnership’s profits less the Partnership’s share of the Local Limited Partnership’s losses and distributions (see Note 3). An investment account is maintained for the limited partnership investment and losses are not recognized once an investment account has decreased to zero. Cash distributions are limited by the Regulatory Agreement between the Local Limited Partnership and HUD to the extent of surplus cash as defined by HUD. Undistributed amounts are cumulative and may be distributed in subsequent years if future operations provide surplus cash in excess of current requirements. Distributions received from the Local Limited Partnership in which the Partnership’s investment account has decreased to zero are recorded as revenue in the year they are received. Advances to the Local Limited Partnership are included with the investment in the Local Limited Partnership to the extent that the advances are not temporary advances of working capital.

The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts of assets andliabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

For purposes of the Statements of Cash Flows, the Partnership considers all highly liquid debt instruments purchased with original maturities of three months or less to be cash equivalents.

Fair Value of Financial Instruments

Financial Accounting Standards Board Accounting Standards Codification (“ASC”) Topic 825, “Financial Instruments”, requires disclosure of fair value information about financial instruments, whether or not recognized in the balance sheet, for which it is practible to estimate fair value. Fair value is defined as the amount at which the instruments could be exchanged in a current transaction between willing parties, other than in a forced or liquidation sale. At December 31, 2010 the Partnership believes that the carrying amount of other assets and liabilities reported on the balance sheet that require such disclosure approximated their fair value due to the short-term maturity of these instruments.

Segment Reporting

ASC Topic 280-10, “Segment Reporting”,established standards for the way that public business enterprises report information about operating segments in annual financial statements and requires that those enterprises report selected information about operating segments in interim financial reports. ASC Topic 280-10 also established standards for related disclosures about products and services, geographic areas, and major customers. As defined in ASC Topic 280-10, the Partnership has only one reportable segment.

Abandonment of Limited Partnership Units

During the years ended December 31, 2010 and 2009, the number of Limited Partnership Units decreased by 17 and 25 units, respectively, due to limited partners abandoning their units. In abandoning his or her Limited Partnership Unit(s), a limited partner relinquishes all right, title, and interest in the Partnership as of the date of abandonment. However, the limited partner is allocated his or her share of net income or loss for that year. The loss per Other Limited Partnership interest on the accompanying statements of operations is calculated based on the number of units outstanding at the beginning of the year. The number of units outstanding was 10,980 and 11,005 at January 1, 2010 and 2009, respectively.

Variable Interest Entities

· the general partner conducts and manages the business of the Local Limited Partnership;

· the general partner has the responsibility for and sole discretion over selecting a property management agent for the Local Limited Partnership’s underlying real estate property;

· the general partner is responsible for approving operating and capital budgets for the property owned by the Local Limited Partnership;

· the general partner is obligated to fund any recourse obligations of the Local Limited Partnership;

· the general partner is authorized to borrow funds on behalf of the Local Limited Partnership; and

Recent Accounting Pronouncement

In December 2009, the Financial Accounting Standards Board issued Accounting Standards Update 2009-17, Improvements to Financial Reporting by Enterprises Involved with Variable Interest Entities, or ASU 2009-17, which is effective for fiscal years beginning after November 15, 2009. ASU 2009-17, which modifies the guidance in ASC Topic 810, “Consolidation”, introduces a more qualitative approach to evaluating VIEs for consolidation and requires a company to perform an analysis to determine whether its variable interests give it a controlling financial interest in a VIE. This analysis identifies the primary beneficiary of a VIE as the entity that has (a) the power to direct the activities of the VIE that most significantly impact the VIE’s economic performance, and (b) the obligation to absorb losses or the right to receive benefits that could potentially be significant to the VIE. In determining whether it has the power to direct the activities of the VIE that most significantly affect the VIE’s performance, ASU 2009-17 requires a company to assess whether it has an implicit financial responsibility to ensure that a VIE operates as designed, requires continuous reassessment of primary beneficiary status rather than periodic, event-driven assessments as previously required, and incorporates expanded disclosure requirements. The Partnership adopted ASU 2009-17 effective January 1, 2010. The adoption of ASU 2009-17 did not have a significant effect on the Partnership’s financial statements.

3. INVESTMENTS IN AND ADVANCES TO LOCAL LIMITED PARTNERSHIP

The Partnership owns a 99% limited partnership interest in one Local Limited Partnership: Hurbell IV Limited Partnership.

The Partnership, as a limited partner, does not have a contractual relationship with the Local Limited Partnership or exercise control over the activities and operations, including refinancing or selling decisions, of the Local Limited Partnership that would require or allow for consolidation. Accordingly, the Partnership accounts for its investment in the Local Limited Partnership using the equity method. Thus, the investment is carried at cost plus the Partnership’s share of the Local Limited Partnership’s profits less the Partnership’s share of the Local Limited Partnership’s losses and distributions. However, since the Partnership is not legally liable for the obligations of the Local Limited Partnership, or is not otherwise committed to provide additional support to it, it does not recognize losses once its investment in the individual Local Limited Partnership, increased for its share of profits, reduced for its share of losses and cash distributions, reaches zero. As of December 31, 2010 and 2009, the investment in the Local Limited Partnership had been reduced to zero.

The Partnership did not recognize approximately $100,000 and $162,000 of its allocated share of losses from Hurbell IV Limited Partnership for the years ended December 31, 2010 and 2009, respectively, as the Partnership’s net carrying basis in this Local Limited Partnership had been reduced to zero. As of December 31, 2010 and 2009, the Partnership has not recognized approximately $2,132,000 and $2,032,000, respectively, of its allocated share of cumulative losses from Hurbell IV Limited Partnership in which its investment is zero.

Hurbell IV Limited Partnership executed certain notes payable as part of the acquisition of the property by the Local Limited Partnership. The notes are nonrecourse notes secured by both the Partnership's and NHP's interests in the Local Limited Partnership and are subordinated to the mortgage note on the property for as long as the mortgage note is insured by HUD. The notes were due November 9, 1999. The noteholders have not exercised any rights under the notes. The Local Limited Partnership has been advised by counsel that the notes are no longer enforceable due to the passage of the applicable statute of limitations. The Local Limited Partnership has also incurred recurring losses from operations and receives advances from its general partner to cover its operations. These conditions raise substantial doubt about the Local Limited Partnership’s and the Partnership’s ability to continue as a going concern. The financial statements do not include any adjustments to reflect the possible future effects of the recoverability and classification of assets or the amounts and classifications of liabilities that may result from the outcome of this uncertainty.

Advances made by the Partnership to the individual Local Limited Partnership are considered part of the Partnership’s investment in the Local Limited Partnership. When advances are made, they are charged to operations as a loss on investment in the Local Limited Partnership using previously unrecognized cumulative losses. To the extent these advances are repaid by the Local Limited Partnership in the future, the repayments will be credited as distributions and repayments received in excess of investment in Local Limited Partnership. As discussed above, due to the cumulative losses incurred by the Local Limited Partnership, the aggregate balance of investment in and advances to the Local Limited Partnership has been reduced to zero at December 31, 2010. During the years ended December 31, 2010 and 2009, the Partnership made no advances to the Local Limited Partnership. There were no amounts owed to the Partnership for working capital advances to the Local Limited Partnership at December 31, 2010 or 2009.

A summary of the unaudited balance sheets of the aforementioned Local Limited Partnership as of December 31, 2010 and 2009, and the unaudited results of operations for each of the two years in the period ended December 31, 2010, are as follows.

The financial statements of Hurbell IV Limited Partnership are prepared on the accrual basis of accounting. The Local Limited Partnership was formed during 1984 for the purpose of acquiring and operating a rental housing project originally organized under Section 236 of the National Housing Act. During the years ended December 31, 2010 and 2009 the project received a total of approximately $475,000 and $426,000, respectively, of rental assistance from HUD.

In 1997 and again in 1999, Congress enacted new ways to determine rent levels for properties receiving HUD’s rental assistance under Section 8 of the United States Housing Act of 1937, as amended, (“Section 8”) after the expiration of their original Section 8 contracts. This legislation affects 100 units, or 100% of the units in which the Partnership has invested at December 31, 2010 and 2009. On October 27, 1997, the President signed into law the Multifamily Assisted Housing Reform and Affordability Act of 1997 (the “1997 Housing Act”). Under the 1997 Housing Act, certain properties assisted under expiring Section 8 contracts and which have been receiving rents deemed to be above comparable market levels for unassisted properties, and financed with HUD-insured mortgage loans, will have, upon the renewal or extension of Section 8 contracts, rents marked to market. This will be accomplished in various ways, the goal being to reduce Section 8 rents to comparable market levels, thereby reducing the Federal Section 8 subsidy obligation, and (ideally) by simultaneously lowering, or eliminating, required debt service costs (and decreasing operating costs) as needed to ensure financial viability at the reduced rent levels. The program also incorporates a requirement to perform any repair or rehabilitation deemed necessary by depositing funds to cover the first twelve month’s work, and making sufficient monthly reserve deposits to ensure work required in succeeding years. In 1999, Congress enacted legislation (the “1999 Housing Act”) that expanded on and clarified the provisions of the 1997 Housing Act, including permitting properties whose Section 8 rents were below comparable market rents to increase their Section 8 rents to market.

The following table indicates the year within which the Section 8 rent subsidy contract expires:

		Subsidized Units	Subsidized Units
		Expiring as a	Expiring as a
	Number of	Percentage of Total	Percentage of
	Units	Subsidized Units	Total Units

2011	100	100%	100%

All of the units (100 in total) receiving rent subsidies from Section 8 have their contracts expiring during the year ending December 31, 2011.The Housing Acts provide for several options under which a Local Limited Partnership may elect, as appropriate, to renew its Section 8 contracts: (1) marking rents up to the comparable market rent, if current rents are below market; (2) renewing rents at the current level, if the level does not exceed comparable market rents, and receiving an operating cost adjustment factor (an “OCAF”) or a budget based rent increase, as long as the rents do not exceed comparable market rents; (3) marking rents down to comparable market rents; (4) marking their rents down to an “exception rent” level, when comparable market rents would be too low to permit continued operation of the property under the Section 8 program, even with full debt restructuring; or (5) opting out of the Section 8 program. For properties assisted by Section 8, but not subject to these provisions (including, but not limited to, properties which do not have underlying HUD insured mortgages, or which have been financed through certain state housing finance agency or bond-financed mortgage programs), rents will be continued at current levels, plus an OCAF or (in some instances) a budget based rent increase. In addition, properties can opt out of the Section 8 program only if very strict notice requirements have been met, including a requirement that HUD, the tenants, and the local governing body, be given twelve months notice of a Local Limited Partnership’s intention to opt out of the program prior to contract termination.

The Local Limited Partnership recorded approximately $475,000 of its revenues during 2010 from HUD under the terms of one or more HAP contracts which provide for rental assistance to the Local Limited Partnership on behalf of low-income tenants who meet certain qualifications. The Local Limited Partnership’s future intentions and potential future changes in HUD regulations and the appropriations of related funds are uncertain, and accordingly, it is not possible to determine the ultimate impact on the operations of the Local Limited Partnership. The current contract expires on February 28, 2011 and subsequent to December 31, 2010 was renewed for an additional year beginning on March 1, 2011.

Fixed assets are recorded on the basis of cost. Depreciation of the buildings and improvements and equipment is computed generally by the straight-line method over the estimated lives of the related assets.

The mortgage note payable is insured by the Federal Housing Administration (FHA) and collateralized by first deeds of trust on the rental property. The note bears interest at 7% per annum. However, FHA makes subsidy payments directly to the mortgage lender reducing the monthly principal and interest payments of the project owner to an effective interest rate of 1% over the forty-year term of the note. The liability of the Local Limited Partnership under the mortgage note is limited to the underlying value of the real estate collateral plus other amounts deposited with the lenders.

A note payable was executed by Hurbell IV Limited Partnership with the former owner as part of the acquisition of the property by the Local Limited Partnership. This note bears simple interest at 9% per annum. The note is a nonrecourse note secured by a security interest in all partnership interests in the Local Limited Partnership and is subordinated to the mortgage note for as long as the mortgage note is insured by HUD. Any payments due from project income are payable from the Local Limited Partnership’s surplus cash, as defined by the HUD Regulatory Agreement. The note may be prepaid in whole or in part at any time without penalty. Neither the Local Limited Partnership nor any partner thereof, present or future, assumes any personal liability for the payment of the note.

The note matured as follows:

Local Partnership	Due Date	Note Amount	Accrued Interest
		(in thousands)
Hurbell IV Limited Partnership	11/9/99	$ 648	$ 1,527

4. TRANSACTIONS WITH AFFILIATED PARTIES

The Partnership accrued administrative and reporting fees payable to the General Partner of approximately $5,000 for both the years ended December 31, 2010 and 2009. As of December 31, 2010 and 2009, the Partnership owed approximately $23,000 and $18,000, respectively, to the General Partner for accrued administrative and reporting fees. As disclosed in Note 3, the property held by the Partnership’s remaining investment in a Local Limited Partnership is under contract to sell during May 2011. The Partnership does not anticipate that it will receive any funds from the sale. Accordingly, the Partnership does not anticipate that it will be able to pay the accrued administrative and reporting fees or the advances it owes at December 31, 2010 to its General Partner and affiliates.

The Local Limited Partnership accrued annual partnership administration fees payable to the General Partner of approximately $7,000 for each of the years ended December 31, 2010 and 2009. Payments of these fees are made to the General Partner from surplus cash available for distribution to partners pursuant to HUD regulations. No payments were made during the years ended December 31, 2010 and 2009. The accumulated fees owed to NHP by Hurbell IV Limited Partnership are approximately $110,000 and $103,000 at December 31, 2010 and 2009, respectively.

5. INCOME TAXES

The Partnership is not taxed on its income. The partners are taxed in their individual capacities based upon their distributive share of the Partnership’s taxable income or loss and are allowed the benefits to be derived from off-setting their distributive share of the tax losses against taxable income from other sources subject to passive loss limitations. The taxable income or loss differs from amounts included in the statements of operations because different methods are used in determining the losses of the Local Limited Partnership as discussed below. The tax loss is allocated to the partner groups in accordance with Section 704(b) of the Internal Revenue Code and therefore is not necessarily proportionate to the interest percentage owned.

6. ALLOCATION OF RESULTS OF OPERATIONS, CASH DISTRIBUTIONS AND GAINS AND LOSSES

FROM SALE OR REFINANCING

Cash received by the Partnership from the sale or refinancing of the underlying property of the Local Limited Partnership, after payment of the applicable mortgage debt and the payment of all expenses related to the transaction is to be distributed in the following manner in accordance with Realty Fund I’s Partnership Agreement.

First, to the General Partner for any unrepaid loans to the Partnership and any unpaid fees (other than disposition and refinancing fees);

Second, to the establishment of any reserves which the General Partner deems reasonably necessary for contingent, unmatured or unforeseen liabilities or obligations of the Partnership.

Third, to the Limited Partners until the Limited Partners have received a return of their capital contributions, after deduction for prior cash distributions from sales or refinancing, but without deduction for prior cash distributions from operations;

Fourth, to the Limited Partners, until each Limited Partner has received an amount equal to a cumulative noncompounded 6% annual return on its capital contribution, after deduction of (a) an amount equal to 50% of the tax losses allocated to the Limited Partner and (b) prior cash distributions from operations and prior cash distributions from sales or refinancing;

Fifth, to the General Partner until the General Partner has received a return of its capital contribution, after deduction for prior cash distributions from sales or refinancing, but without deduction for prior cash distributions from operations;

Sixth, to the General Partner for disposition and refinancing fees, including prior disposition and refinancing fees which have been accrued but are unpaid;

Seventh, to the partners with positive capital accounts to bring such accounts to zero; and

Finally, 85% of the remaining sales proceeds to the Limited Partners and 15% to the General Partner.

Net income or loss from operations of the Partnership is allocated 98% to the Limited Partners, 1% to the General Partner and 1% to the Original Limited Partner.

Third, to the Limited Partners up to the aggregate amount of capital contributions of the Limited Partners, after deduction for prior cash distributions from sales or refinancing, but without deduction for prior cash distributions from operations, in the same proportion that each Limited Partner’s capital contribution bears to the aggregate of all Limited Partners’ capital contributions;

Fourth, to the Limited Partners, until each Limited Partner has been allocated an amount equal to a cumulative noncompounded 6% annual return on its capital contribution, after deduction of (a) an amount equal to 50% of the tax losses allocated to the Limited Partner and (b) prior cash distributions from operations and prior cash distributions from sales or refinancing;

Fifth, to the General Partner up to the aggregate amount of capital contributions made by the General Partner, after deduction for prior cash distributions from sales or refinancing, but without deduction for prior cash distributions from operations; and

Finally, 85% of the remaining gain to the Limited Partners and 15% to the General Partner.

Losses for federal income tax purposes realized in the event of dissolution of the Partnership or upon sale of interests in a Local Limited Partnership or underlying property will be allocated 85% to the Limited Partners and 15% to the General Partner.

Item 9A. Controls and Procedures.

(a) Disclosure Controls and Procedures

The Partnership’s management, with the participation of the principal executive officer and principal financial officer of the General Partner, who are the equivalent of the Partnership’s principal executive officer and principal financial officer, respectively, has evaluated the effectiveness of the Partnership’s disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) as of the end of the period covered by this report. Based on such evaluation, the principal executive officer and principal financial officer of the General Partner, who are the equivalent of the Partnership’s principal executive officer and principal financial officer, respectively, have concluded that, as of the end of such period, the Partnership’s disclosure controls and procedures are effective.

Management’s Report on Internal Control Over Financial Reporting

The Partnership’s management is responsible for establishing and maintaining adequate internal control over financial reporting. Internal control over financial reporting is defined in Rule 13a-15(f) and 15d-15(f) under the Exchange Act as a process designed by, or under the supervision of, the principal executive and principal financial officers of the General Partner, who are the equivalent of the Partnership’s principal executive officer and principal financial officer, respectively, and effected by the Partnership’s management and other personnel to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles and includes those policies and procedures that:

· pertain to the maintenance of records that in reasonable detail accurately and fairly reflect the transactions and dispositions of assets;

· provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures are being made only in accordance with authorizations of the Partnership’s management; and

· provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Projections of any evaluation of effectiveness to future periods are subject to the risks that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

The Partnership’s management assessed the effectiveness of the Partnership’s internal control over financial reporting as of December 31, 2010. In making this assessment, the Partnership’s management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) in Internal Control-Integrated Framework.

Based on their assessment, the Partnership’s management concluded that, as of December 31, 2010, the Partnership’s internal control over financial reporting is effective.

This annual report does not include an attestation report of the Partnership’s registered public accounting firm regarding internal control over financial reporting. Management’s report was not subject to attestation by the Partnership’s registered public accounting firm pursuant to rules of the Securities and Exchange Commission that permit the Partnership to provide only management’s report in this annual report.

(b) Changes in Internal Control Over Financial Reporting.

There has been no change in the Partnership’s internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) during the fourth quarter of 2010 that has materially affected, or is reasonably likely to materially affect, the Partnership’s internal control over financial reporting.

Item 9B. Other Information.

None.
