Item 8.01 .                       Other Events

On August 26, 2008, RMR F.I.R.E. Fund (“RFR”) and two other publicly traded closed end funds, all of which are managed by RMR Advisors, Inc. (the “Advisor”), announced that their Boards of Trustees had approved proposed mergers of their respective funds and that a registration statement on Form N-14, including a preliminary Joint Proxy Statement/Prospectus, was filed with the U.S. Securities and Exchange Commission (the “SEC”) in connection with those mergers, which are referred to in the Form N-14 as “reorganizations.”  Those other two funds affected are RMR Real Estate Fund (“RMR”) and RMR Hospitality and Real Estate Fund (“RHR”).  If the mergers proceed, each fund will become part of RMR Real Estate Income Fund, a newly formed Delaware statutory trust (“RIR”), which is also managed by the Advisor.  A copy of the press release is attached as Exhibit 99.1 to this Current Report on 8-K.

This communication is being made in respect of the proposed reorganizations of RHR, RFR and RMR into RIR.  In connection with the proposed reorganizations, RIR has filed with the SEC a Registration Statement on Form N-14 containing a preliminary Joint Proxy Statement/Prospectus, which includes proxy statement disclosure of RHR and RFR.  Each fund plans to file with the SEC other documents related to the proposed Reorganizations.  RIR, RMR, RHR and RFR and their respective trustees, officers and employees and the Advisor and its shareholders, officers and employees and other persons may be deemed to be participants in the solicitation of proxies with respect to the proposed reorganizations.  Investors and shareholders may obtain more detailed information regarding the direct and indirect interests of RIR’s, RMR’s, RHR’s and RFR’s respective trustees, officers and employees and the Advisor’s shareholders, officers and employees and other persons by reading the preliminary and definitive Joint Proxy Statements/Prospectuses regarding the reorganizations, filed with the SEC, when they become available.  The registration statement has not yet become effective, and the information contained in that filing, including the preliminary Joint Proxy Statements/Prospectus, is not complete and is subject to change.  This communication is not intended to, and shall not, constitute an offer to purchase or sell shares of any of the affected funds; nor is the press release intended to solicit a proxy from any shareholder of any of the affected funds.  The solicitation of the purchase or sale of securities or of proxies to effect the reorganizations may only be made by a final, effective registration statement, which includes a Joint Proxy Statements/Prospectus, after it is declared effective by the SEC.  INVESTORS AND SECURITY HOLDERS OF THE FUNDS ARE URGED TO READ THE JOINT PROXY STATEMENT/ PROSPECTUS AND OTHER DOCUMENTS FILED WITH THE SEC CAREFULLY IN THEIR ENTIRETY WHEN THEY BECOME AVAILABLE BECAUSE THEY WILL CONTAIN IMPORTANT INFORMATION ABOUT THE PROPOSED REORGANIZATIONS.

Investors may obtain free copies of the Registration Statement and the Joint Proxy Statement/Prospectus and other documents (when they become available) filed with the SEC at the SEC’s web site at www.sec.gov.  In addition, free copies of the Joint Proxy Statement/Prospectus and other documents filed with the SEC may also be obtained after the Registration Statement becomes effective by directing a request to: RMR Advisors, Inc., 400 Centre Street, Newton, MA, 02458 or by calling the toll-free number: (866) 790-8165.
