REPORT OF INDEPENDENT CERTIFIED PUBLIC ACCOUNTANTS

Board of Directors

Independence Realty Trust, Inc.

We have audited the accompanying statements of revenue and certain expenses (the Historical Summary) of a property commonly referred to as Centrepoint Apartments (the Property) for the year ended December 31, 2010. This Historical Summary is the responsibility of the Property’s management. Our responsibility is to express an opinion on the Historical Summary based on our audit.

We conducted our audit in accordance with auditing standards generally accepted in the United States of America, as established by the American Institute of Certified Public Accountants. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the Historical Summary is free of material misstatement. An audit includes 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 Property’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 Historical Summary, assessing the accounting principles used, and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audit provides a reasonable basis for our opinion.

As described in Note 1 to the Historical Summary, the accompanying Historical Summary was prepared for the purpose of complying with the rules and regulations of the Securities and Exchange Commission and is not intended to be a complete presentation of the Property’s revenue and expenses.

In our opinion, the Historical Summary referred to above presents fairly, in all material respects, the revenue and certain expenses for the year ended December 31, 2010 of the Property on the basis of accounting described in Note 1 to the Historical Summary.

CENTREPOINT APARTMENTS

NOTES TO STATEMENTS OF REVENUE AND CERTAIN EXPENSES

For the Nine Month Periods Ended September 30, 2011 and 2010 and

for the Year Ended December 31, 2010

NOTE 1: ORGANIZATION AND BASIS OF PRESENTATION

The accompanying statements of revenue and certain expenses (the Historical Summary) include the revenue and certain expenses of the following property (hereinafter referred to as the Property):

On December 16, 2011 a definitive agreement was entered into for the contribution of the Property to Independence Realty Trust, Inc. (IRT) for a purchase price equal to $29.5 million.

The Historical Summary has been prepared for the purpose of complying with the provisions of Article 3-14 of Regulation S-X promulgated by the Securities and Exchange Commission (SEC), which requires certain information with respect to real estate operations to be included with certain filings with the SEC. The Historical Summary includes the historical revenue and certain operating expenses of the Property, exclusive of items which may not be comparable to the proposed future operations of the Property. Material amounts that would not be directly attributable to future operating results of the Property are excluded, and the Historical Summary is not intended to be a complete presentation of the Property’s revenue and expenses. Items excluded consist of interest on mortgages and depreciation for the property.

The Historical Summary presents the revenue and certain expenses of the Property during RAIT’s ownership period and may not be comparable to future periods. Management is not aware of any material factors relating to the Property other than those already described above that would cause the reported financial information not to be necessarily indicative of future operating results. In the opinion of Management, all adjustments, consisting only of normal recurring adjustments, necessary to present fairly the interim periods results of operations are included. The results of operations for the interim periods presented are not necessarily indicative of the results for the full year.

In the preparation of the accompanying Historical Summary, subsequent events were evaluated through January 4, 2012, the date the financial statements were available to be issued.

NOTE 2: SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Rental income attributable to residential leases is recorded when due from residents, generally upon the first day of the month. Leases are for periods of up to one year, with rental payments due monthly. Other income results from fees for late payments, cleaning, damages, storage, parking, and laundry facilities and is recorded when earned.

The Property is managed by Jupiter Communities LLC (the Management Company) during RAIT’s ownership period. The Management Company receives fees of 3% of the monthly gross receipts, or gross revenue as defined, of the Property. The Management Company also receives asset management fees in the amount of 5% of construction costs for projects in excess of certain thresholds. For the nine month periods ended September 30, 2011 and 2010, property and construction management fees were $64,554 and $57,954, respectively (unaudited). For the year ended December 31, 2010, property and construction management fees were $76,899.

The Property recognizes bad debt expense for uncollectible receivables. Management’s estimate of bad debt expense is based on expected and inherent risks of collectability for receivables from tenants. For the nine month periods ended September 30, 2011 and 2010, bad debt expenses were $(8,110) and $1,499, respectively (unaudited). For the year ended December 31, 2010, bad debt expenses were $2,611.

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

NOTE 3: MORTGAGE DEBT

The Property is encumbered by a first mortgage held by RAIT. A summary of the mortgage, as of September 30, 2011 and as of December 31, 2010, is as follows:

NOTE 4: COMMITMENTS AND CONTINGENCIES

Litigation

The Property may be subject to various claims and legal proceedings that arise in the ordinary course of its business activities. Management believes that any liability that may ultimately result from the resolution of these matters will not have a material adverse effect on the financial condition or results of operations of the Property.

PRO FORMA CONSOLIDATED FINANCIAL INFORMATION

AS OF SEPTEMBER 30, 2011

The following sets forth our unaudited pro forma consolidated balance sheet as of September 30, 2011 and our unaudited pro forma consolidated statements of income for the nine month period ended September 30, 2011 and for the year ended December 31, 2010. The unaudited pro forma consolidated balance sheet is presented as if we acquired Centrepoint Apartments (the Property) as of September 30, 2011 for balance sheet purposes and as of the beginning of the respective periods for income statement purposes.

Although pro forma financial information is not a measurement of performance, we believe that pro forma financial information is important because it gives effect to the acquisition of the Property as if it had become effective at the beginning of the period presented. The manner in which we calculate pro forma financial information may differ from similarly titled measures reported by other companies.

The unaudited pro forma consolidated financial statements included in this registration statement are presented for informational purposes only. This information includes various estimates and may not necessarily be indicative of the financial condition or results of operations that would have occurred if the acquisition of the Property had been completed on the date or at the beginning of the period indicated or which may be obtained in the future. The unaudited pro forma consolidated balance sheet and income statements and accompanying notes should be read in conjunction with our historical consolidated financial statements included in our registration statement on Form S-11, which was declared effective by the Securities and Exchange Commission (SEC) on June 10, 2011.

The statements contained in this filing may include forward-looking statements within the meaning of the U.S. federal securities laws. Although we believe that the expectations reflected in such forward-looking statements are based on reasonable assumptions, it can give no assurance that our expectations will be achieved. As forward-looking statements, these statements involve risks and uncertainties that could cause actual results to differ materially from the expected results. These risks and uncertainties include, but are not limited to, uncertainties affecting real estate businesses generally, risks relating to acquisition activities and risks relating to leasing and re-leasing activities.

NOTES TO UNAUDITED PRO FORMA FINANCIAL INFORMATION

(Dollars in thousands, except per share and unit data)

The following notes discuss the pro forma adjustments to our unaudited pro forma consolidated balance sheet as of September 30, 2011 associated with our acquisition of the Property.

The following table summarizes our sponsor’s historical cost of the Property as of September 30, 2011:

The issuance of limited partnership units will be treated as non-controlling interests in our consolidated financial statements equal to the value of the units issued. However, as the acquisition of the Property will be accounted for at our sponsor’s historical cost, the value of the 1,190,000 limited partnership units issued to our sponsor will be less than the value determined in the preceding table because the carrying amount of the Property by our sponsor is less than the contribution value indicated above.

The adjustment to our non-controlling interest as a result of the acquisition of the Property can be calculated as follows:

The following notes discuss the pro forma adjustments to our unaudited pro forma consolidated statements of income for the nine month period ended September 30, 2011 and for the year ended December 31, 2010 associated with our acquisition of the Property.
