SCHEDULE 13D


CUSIP No. Not Applicable		Page 8 of 12 Pages

Introductory Note

This Amendment No. 24 (this “Amendment”) is filed with respect to the issuer, Angeles Income Properties 6, LP, a Delaware limited partnership (the “Delaware Partnership”), successor by merger to Angeles Income Properties, Ltd. 6, a California limited partnership (the “California Partnership”), by AIMCO Properties, L.P. (“AIMCO Properties”), AIMCO-GP, Inc. (“AIMCO GP”), Apartment Investment and Management Company (“AIMCO”), AIMCO IPLP, L.P. (“AIMCO IPLP”), AIMCO/IPT, INC. (“AIMCO/IPT”) and Cooper River Properties, L.L.C. (“Cooper River” and, together with AIMCO Properties, AIMCO GP, AIMCO, AIMCO IPLP and AIMCO/IPT, the “Reporting Persons”). This Amendment No. 24 amends and supplements the statement on Schedule 13D, as amended and supplemented to date (the “Schedule 13D”), previously filed with the Securities and Exchange Commission with respect to the California Partnership by the Reporting Persons or certain of their affiliates.

The Schedule 13D is amended to make the following changes to Items 4 and 5:

Item 4.

Purpose of Transaction

Item 4 is hereby supplemented by the addition of the following information:

Merger Agreement

On November 15, 2011, the California Partnership entered into an Amended and Restated Agreement and Plan of Merger (the “Merger Agreement”) with the Delaware Partnership, AIMCO Properties and AIMCO AIP 6 Merger Sub LLC, a Delaware limited liability company of which AIMCO Properties is the sole member (the “Merger Subsidiary”). The Merger Agreement provides for (i) the merger of the California Partnership with and into the Delaware Partnership, with the Delaware Partnership as the surviving entity (the “First Merger”), and (ii) after the First Merger, the merger of the Merger Subsidiary with and into the Delaware Partnership, with the Delaware Partnership as the surviving entity (the “Second Merger”).

First Merger

Completion of the First Merger was subject to approval by a majority in interest of the limited partnership interests of the California Partnership. Immediately prior to consummation of the First Merger, AIMCO Properties and its affiliates owned 27,739 of the 47,280 issued and outstanding units of limited partnership interest (the “Units”) in the California Partnership (or approximately 58.67% of the number of units outstanding).

On January 23, 2012, AIMCO Properties and its affiliates took action by written consent to approve the Merger Agreement and the transactions contemplated thereby, including the First Merger and the Amendment (as defined below). AIMCO Properties and its affiliates voted all of their Units of limited partnership interest in the California Partnership in favor of the Merger Agreement and the transactions contemplated thereby, including the First Merger and the Amendment. As a result, the Merger Agreement and the transactions contemplated thereby, including the First Merger and the Amendment, were approved by a total of 27,739 Units in the California Partnership, or approximately 58.67% of the number of Units outstanding.

SCHEDULE 13D


CUSIP No. Not Applicable		Page 9 of 12 Pages

In the First Merger, each Unit of limited partnership interest in the California Partnership was converted into an identical unit of limited partnership interest in the Delaware Partnership, and each general partnership interest in the California Partnership held by a general partner was converted into an equivalent general partnership interest in the Delaware Partnership. All interests in the Delaware Partnership outstanding immediately prior to the First Merger were cancelled in the First Merger. The voting and other rights of the limited partners provided for in the Agreement of Limited Partnership of the California Partnership, dated June 1, 1987, and as further amended to date (the “Partnership Agreement”), were not changed as a result of the First Merger.

Upon completion of the First Merger, the certificate of limited partnership of the Delaware Partnership (the “Certificate of Limited Partnership”) became the certificate of limited partnership of the first surviving entity.

In connection with the First Merger, the partnership agreement of the California Partnership was adopted as the partnership agreement of the surviving entity, as modified by the Amendment to Agreement of Limited Partnership, dated as of January 23, 2012 by and among Angeles Realty Corporation II, a California corporation and the managing general partner of the California Partnership, and the each of the limited partners of the California Partnership (the “Amendment”). Pursuant to the Amendment: (i) references in the Partnership Agreement to the laws, statutes or regulations of the state of California, including the California Uniform Limited Partnership Act, were amended to refer to the laws statutes or regulations of the state of Delaware, including the Delaware Revised Uniform Limited Partnership Act; (ii) a description of the First Merger was added; and (iii) the name of the partnership was changed to “Angeles Income Properties 6, LP.”

Second Merger

Completion of the Second Merger was subject to approval by a majority in interest of the limited partnership interests of the Delaware Partnership. Immediately prior to the consummation of the Second Merger, AIMCO Properties and its affiliates owned 27,739 of the 47,280 issued and outstanding Units in the Delaware Partnership (or approximately 58.67% of the number of Units outstanding).

Immediately following consummation of the First Merger, on January 23, 2012, AIMCO Properties and its affiliates took action by written consent to approve the Merger Agreement and the transactions contemplated thereby, including the Second Merger. AIMCO Properties and its affiliates voted all of their Units of limited partnership interest in the Delaware Partnership in favor of the Merger Agreement and the transactions contemplated thereby, including the Second Merger. As a result, the Merger Agreement and the transactions contemplated thereby, including the Second Merger, were approved by a total of 27,739 Units in the Delaware Partnership, or approximately 58.67% of the number of Units outstanding.

SCHEDULE 13D


CUSIP No. Not Applicable		Page 10 of 12 Pages

In the Second Merger, each Unit in the Delaware Partnership outstanding immediately prior to the Second Merger and held by limited partners (other than Units as to which appraisal rights are elected) was converted into the right to receive, at the election of the limited partner, either (i) $268.04 in cash (the “Cash Consideration”) or (ii) 11.65 partnership common units of AIMCO Properties. Limited partners who are residents of the State of California, or who fail to make an election, will receive only the Cash Consideration.

AIMCO Properties’ interest in the Merger Subsidiary was converted into 100 units of limited partnership interest in the Delaware Partnership, and AIMCO Properties became the sole limited partner of the Delaware Partnership. Each general partnership interest in the Delaware Partnership outstanding immediately prior to the consummation of the Second Merger remained outstanding and unchanged after the Second Merger.

Upon completion of the Second Merger (i) the Certificate of Limited Partnership became the certificate of limited partnership of the surviving entity, and (ii) the Partnership Agreement, as modified by the Amendment, remained unchanged and became the partnership agreement of the surviving entity.
