Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the Statement is free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the Statement. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the Statement. We believe that our audit of the Statement provides a reasonable basis for our opinion.

As described in Note 1 to the Statement, the accompanying Statement was prepared for the purpose of complying with the provisions of Article 3-14 of Regulation S-X promulgated by the U.S. Securities and Exchange Commission (for inclusion in Form 8-K of Resource Real Estate Opportunity REIT, Inc.) and is not intended to be a complete presentation of the Property’s revenues and expenses.

NOTE 1. Basis of Presentation

On March 27, 2012, Resource Real Estate Opportunity REIT, Inc. (the “Company”) acquired an 856-unit garden apartment complex located in Houston, Texas (“Bristol Apartments” or the “Property”).

The statements of revenues and certain operating expenses (the “Statements”) have been prepared for the purpose of complying with the provision of Article 3-14 of Regulation S-X promulgated by the U.S. Securities and Exchange Commission (the “SEC”), which required certain information with respect to real estate operations to be included with certain filings with the SEC. The Statements include the historical revenues and certain operating expenses of Bristol Apartments, exclusive of interest income and interest expense, early termination fees, asset management fees, depreciation and amortization, and corporate expenses. Amounts included in property management fees include routine compensation paid to a third party managing property operations. The apartment complex was purchased for $11.4 million. The aggregate purchase price, which included acquisition and financing costs, escrowed funds and advances and other assets and liabilities assumed, was approximately $11.9 million and was funded entirely with capital from the Company.

In the opinion of the Company’s management, all adjustments necessary for a fair presentation of the Statements for the period from January 1, 2012 to March 27, 2012 (unaudited) and for the year ended December 31, 2011 have been included. Such adjustments consisted of normal recurring items. Interim results are not necessarily indicative of results for a year.

NOTE 2. Summary of Significant Accounting Policies

Revenue Recognition: Revenue is derived from the rental of residential housing units with lease agreement terms of generally one year or less. Bristol Apartments recognizes rent as income on a straight line basis over the term of the related lease. Included within rental income is tenant reimbursement income consisting of charges billed to tenants for trash removal and utilities, and other income amounts such as administrative, application and late fees, all of which are recognized in income as earned.

Use of Estimates: The preparation of the statements of revenues and certain operating expenses, in conformity with accounting principles generally accepted in the United States of America, requires management to make estimates and assumptions that affect the reported amounts of revenues and certain operating expenses during the reporting period. Actual results could differ from those estimates.

NOTE 3. Subsequent Events

The Property’s management evaluated all events and transactions that occurred after December 31, 2011 through June 12, 2012, the date the statements of revenues and certain operating expenses were available to be issued. During this period, the Property did not have any material subsequent events other than as disclosed in Note 1.
