This Amendment No. 1 (this “Amendment”) to Schedule 13D amends the Schedule 13D (the “Schedule 13D”) filed by the reporting person, dated December 9, 1993, and amends the following Items of the Schedule 13D:

Item 1. Security and Issuer. This statement relates to the common stock of Security Land and Development Corporation, a Georgia corporation, whose principal executive office is located at 2816 Washington Road, #103, Augusta, Georgia 30909.

Item 2. Identity and Background.

(a) The name of the reporting person is Robert M. Flanagin.

(b) Mr. Flanagin’s home address is 2002 Wrightsboro Road, Apt. B, Augusta, Georgia 30904.

(c) Mr. Flanagin works as a realtor and developer from his home office located at 2002 Wrightsboro Road, Apt. B., Augusta, Georgia 30904.

(d) During the last five years, the reporting person has not been convicted in a criminal proceeding (excluding traffic violations or similar misdemeanors).

(e) During the last five years, the reporting person was not a party to a civil proceeding of a judicial or administrative body of competent jurisdiction and as a result of such proceeding was or is subject to a judgment, decree or final order enjoining future violations of, or prohibiting or mandating activities subject to, federal or state securities laws or finding any violation with respect to such laws.

Item 3. Source and Amount of Funds or Other Consideration.

Mr. Flanagin did not acquire or dispose any common stock of the Issuer in 2016 or to date in 2017. The reporting person has paid for all stock purchases with personal funds, except for shares received by gift or devise.

Item 4. Purpose of Transaction.

All of the shares of Common Stock beneficially owned by Mr. Flanagin are held for investment. Mr. Flanagin may, from time to time, depending upon market conditions, liquidity needs and other investment considerations, purchase additional shares of common stock for investment or dispose of shares of Common Stock. As a director of the Issuer, Mr. Flanagin expects to regularly explore potential actions and transactions which may be advantageous to the Issuer, including, but not limited to, possible acquisitions, dispositions, reorganizations, mergers, or other material changes in the business, corporate structure, management, policies, governing instruments, capitalization, securities or regulatory or reporting obligations of the Issuer.

As a director of the Issuer, Mr. Flanagin approved a tender offer by the Issuer of 48.2% (subsequently reduced to 38.1%) of the common stock of the Issuer. Mr. Flanagin and certain members of his family (the “Flanagin Family”) collectively own 44.7% of the Issuer’s common stock, which could allow them to collectively exercise control over the Issuer. Mr. Flanagin and the other members of the Flanagin Family are filing persons with respect to a Schedule 13E-3 as amended regarding the Company’s tender offer to purchase up to 2,000,000 shares of its common stock, par value $0.10 per share, at a revised purchase price of $1.75 per share. Such tender offer could result in:

(e) a material change in the capitalization of the Issuer, and

(i) the common stock of the Issuer becoming eligible for termination of registration pursuant to section 12(g)(4) of the Act.

Except as noted above, Mr. Flanagin has no plans or proposals which would relate to or result in any of the matters referred to in paragraphs (a) through (j) of the instructions to Item 4 of Schedule 13D.

Item 5. Interest in Securities of the Issuer.

(a) Mr. Flanagin beneficially owns an aggregate of 523,147 shares of the Issuer's common stock, constituting almost 10.0% of the number of shares of such common stock outstanding on the date hereof. Since the date of the Schedule 13D, the beneficial ownership by Mr. Flanagin has been reflected on the Issuer’s annual reports on Form 10-K, the disclosures of which on such annual reports are incorporated herein by reference.

(b) With respect to the 523,147 shares of common stock beneficially owned by Mr. Flanagin, he has the sole power to vote or to direct the vote and the sole power to dispose or to direct the disposition.

(d) Not applicable.

(e) Not applicable

Item 6. Contracts, Arrangements, Understandings or Relationships With Respect to Securities of the Issuer.

Not applicable.

Item 7. Material to be Filed as Exhibits.
