Explanatory Note

Pursuant to the requirements of the Securities Exchange Act of 1934, as amended, Landmark Apartment Trust of America, Inc. (the “Company”) hereby amends the Current Report on Form 8-K filed with the Securities and Exchange Commission on July 29, 2013 (the “July 29, 2013 Form 8-K”) to provide the required financial information relating to the completed acquisitions of the three multifamily apartment communities described in such report: the Brentwood Apartments property, the Tanglewood Apartments property, and the Gleneagles Apartments property. Additionally, as disclosed in the Current Report on Form 8-K filed on September 13, 2013, the Company completed the acquisition of the multifamily apartment communities known as Battleground Park Apartments and Briley Parkway Apartments, and the Company has provided herein the financial information relating to the completion of such properties. As disclosed in the Current Report on Form 8-K filed on July 8, 2013, the Company also completed the acquisition of the multifamily apartment community known as Barton Creek, and the Company has provided herein the financial information relating to the completion of the Barton Creek property. While the acquisition of any one of these six properties was individually insignificant for purposes of the reporting requirements of Form 8-K and Rule 3-14, and the acquisition of any one of the properties was not conditioned upon the acquisition of any of the other properties, the properties are related properties, which are significant in the aggregate.

A description of the properties is set forth below (dollars in thousands):

After a reasonable inquiry, the Company is not aware of any other material factors relating to these properties that would cause the reported financial information not to be necessarily indicative of future operating results. The Company and its operations are, however, subject to a number of risks and uncertainties. For a discussion of such risks, see the risks identified in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2012 under Item 1A Risk Factors and in the other reports filed by the Company with the SEC.

INDEPENDENT AUDITOR’S REPORT

To the Board of Directors and Stockholders of Landmark Apartment Trust of America, Inc.

We have audited the accompanying combined statements of revenues and certain expenses of Mission Barton Creek, DST, Mission Brentwood, DST, Mission Gleneagles, DST, Mission Tanglewood, DST, Mission Battleground Park, DST, and Mission Briley Parkway, DST (the “Properties”) for the year ended December 31, 2012.

Management’s Responsibility for the Statements of Revenue and Certain Expenses

Management is responsible for the preparation and fair presentation of the combined statements of revenue and certain expenses in accordance with accounting principles generally accepted in the United States of America; this includes the design, implementation, and maintenance of internal control relevant to the preparation and fair presentation of the combined statements of revenue and certain expenses that are free from material misstatement, whether due to fraud or error.

Auditor’s Responsibility

Our responsibility is to express an opinion on the combined statements of revenue and certain expenses based on our audits. We conducted our audits in accordance with auditing standards generally accepted in the United States of America. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the combined statements of revenue and certain expenses are free from material misstatement.

An audit involves performing procedures to obtain audit evidence about the amounts and disclosures in the combined statements of revenue and certain expenses. The procedures selected depend on our judgment, including the assessment of the risks of material misstatement of the combined statements of revenue and certain expenses, whether due to fraud or error. In making those risk assessments, we consider internal control relevant to the Properties’ preparation and fair presentation of the combined statements of revenue and certain expenses in order to design audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Properties’ internal control. Accordingly, we express no such opinion. An audit also includes evaluating the appropriateness of accounting policies used and the reasonableness of significant accounting estimates made by management, as well as evaluating the overall presentation of the combined statements of revenue and certain expenses. We believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis for our audit opinion.

Opinion

In our opinion, the combined statements of revenue and certain expenses referred to above present fairly, in all material respects, the revenue and certain expenses described in Note 1 of the Properties for the year ended December 31, 2012, in accordance with accounting principles generally accepted in the United States of America.

Emphasis of Matter

As discussed in Note 1, the accompanying combined statements of revenue and certain expenses were prepared for the purpose of complying with the rules and regulations of the Securities and Exchange Commission (for inclusion in the Form 8-K/A of Landmark Apartment Trust of America, Inc.) and are not intended to be a complete presentation of the Properties’ revenue and expenses. Our opinion is not modified with respect to this matter.
