(a) Following a competitive bidding process undertaken by the Audit Committee of the Board of Trustees of INREIT Real Estate Investment Trust (“INREIT”), the Audit Committee approved the selection of Baker Tilly Virchow Krause, LLP (“Baker Tilly”) to serve as INREIT’s independent registered public accounting firm for the fiscal year ending December 31, 2013. Widmer Roel, PC (“Widmer Roel”) was notified that its dismissal would become effective upon the filing of INREIT’s Annual Report on Form 10-K for the fiscal year ended December 31, 2012. INREIT filed such Annual Report on March 29, 2013, whereby Widmer Roel’s term as INREIT’s independent registered public accounting firm ended on March 29, 2013.

Widmer Roel’s reports on INREIT’s consolidated financial statements for each of the fiscal years ended December 31, 2012 and December 31, 2011 did not contain an adverse opinion or disclaimer of opinion, nor were they qualified or modified as to uncertainty, audit scope or accounting principles.

During the two fiscal years ended December 31, 2012 and December 31, 2011 and the subsequent interim period through the date of dismissal, there were (1) no disagreements between INREIT and Widmer Roel on any matter of accounting principles or practices, financial statement disclosure or auditing scope or procedure which, if not resolved to Widmer Roel’s satisfaction, would have caused Widmer Roel to make reference to the subject matter of the disagreement in connection with its report for such years; and (2) there were no reportable events as described in Item 304(a)(1)(v) of Regulation S-K.

INREIT provided Widmer Roel with a copy of the foregoing disclosures and requested Widmer Roel to furnish it with a letter addressed to the Securities and Exchange Commission stating whether it agrees with the above statements in compliance with Item 304(a)(3) of Regulation S-K. A copy of Widmer Roel’s letter dated March 26, 2013, stating its agreement with the above statements, is filed with this Current Report on Form 8-K as Exhibit 16.1.

(b) Effective March 29, 2013, Baker Tilly was engaged as INREIT’s independent registered public accounting firm for the fiscal year ending December 31, 2013. At no time during the two fiscal years ended December 31, 2012 and December 31, 2011 and the subsequent interim period through March 29, 2013 did INREIT (or anyone acting on its behalf) consult with Baker Tilly with respect to either (1) the application of accounting principles to a specified transaction, either completed or proposed, or the type of audit opinion that might be rendered on INREIT’s consolidated financial statements; or (2) any other matter that was either the subject of a disagreement, as defined in Item 304(a)(1)(iv) of Regulation S-K and the related instructions, or a reportable event as described in Item 304(a)(1)(v) of Regulation S-K.
