Item 6.02. Change of Servicer or Trustee.

On January 30, 2007 (the “Closing Date”), RALI Series 2007-QO1 Trust (the “Issuing Entity”) issued and sold Mortgage Asset-Backed Pass-Through Certificates, Series 2007-QO1. As of the Closing Date, Homecomings Financial, LLC (“Homecomings”) and GMAC Mortgage, LLC (“GMACM”), each an affiliate of the master servicer, Residential Funding Company, LLC, and the depositor, Residential Accredit Loans, Inc., acted as subservicers of approximately 85.7% and 14.3%, respectively, by principal balance of the mortgage loans owned by the Issuing Entity.

Residential Capital, LLC (“ResCap”), which owns indirectly all of the equity of both Homecomings and GMACM, has restructured the operations of Homecomings and GMACM. As a result of such restructuring, on September 24, 2007, Homecomings transferred its servicing platform and certain employees responsible for the servicing function to its affiliate GMACM.

Subsequent to the transfer of the servicing platform and employees from Homecomings to GMACM, GMACM became the subservicer for all of the mortgage loans owned by the Issuing Entity, and Homecomings will no longer service any of the mortgage loans. In addition, GMACM will be servicing all of the GMACM and Homecomings servicing portfolios, which will consist of the aggregate of the amounts set forth below under the headings “GMAC Mortgage LLC Primary Servicing Portfolio” and “Homecomings Financial, LLC Servicing Portfolio.”

GMACM is a Delaware limited liability company and a wholly-owned subsidiary of GMAC Residential Holding Company, LLC, which is a wholly owned subsidiary of ResCap. ResCap is a Delaware limited liability company and a wholly-owned subsidiary of GMAC Mortgage Group, LLC, which is a wholly-owned subsidiary of GMAC LLC. On August 24, 2007, Fitch Ratings reduced GMACM’s residential primary subservicer rating and residential primary servicer rating for Alt-A product from RPS1 to RPS1- and placed the servicer ratings on Rating Watch Negative.

GMACM began acquiring, originating and servicing residential mortgage loans in 1985 through its acquisition of Colonial Mortgage Service Company, which was formed in 1926, and the loan administration, servicing operations and portfolio of Norwest Mortgage, which entered the residential mortgage loan business in 1906. These businesses formed the original basis of what is now GMACM.

GMACM maintains its executive and principal offices at 1100 Virginia Drive, Fort Washington, Pennsylvania 19034. Its telephone number is (215) 734-5000.

In addition, GMACM purchases mortgage loans originated by GMAC Bank, which is wholly-owned by IB Finance Holding Company, LLC, a subsidiary of ResCap and GMAC LLC, and which is an affiliate of GMACM. Formerly known as GMAC Automotive Bank, GMAC Bank, a Utah industrial bank was organized in 2001. As of November 22, 2006, GMAC Bank became the successor to substantially all of the assets and liabilities of GMAC Bank, a federal savings bank.

GMACM generally retains the servicing rights with respect to loans it sells or securitizes, and also occasionally purchases mortgage servicing rights from other servicers or acts as a subservicer of mortgage loans (and does not hold the corresponding mortgage servicing right asset).

As of the six months ended June 30, 2007, GMACM acted as primary servicer and owned the corresponding servicing rights on approximately 2,271,474 of residential mortgage loans having an aggregate unpaid principal balance of approximately $284 billion, and GMACM acted as subservicer (and did not own the corresponding servicing rights) on approximately 334,864 loans having an aggregate unpaid principal balance of over $70.5 billion.

The following tables set forth the dollar amount of mortgage loans serviced by GMACM for the periods indicated, and the number of such loans for the same period. GMACM was the servicer of a residential mortgage loan portfolio of approximately $153.6 billion, $13.9 billion, $17.6 billion and $7.0 billion during the year ended December 31, 2003 backed by prime conforming mortgage loans, prime non-conforming mortgage loans, government mortgage loans and second-lien mortgage loans, respectively. GMACM was the servicer of a residential mortgage loan portfolio of approximately $211.5 billion, $32.0 billion, $18.2 billion and $22.8 billion during the six months ended June 30, 2007 backed by prime conforming mortgage loans, prime non-conforming mortgage loans, government mortgage loans and second-lien mortgage loans, respectively. The percentages shown under “Percentage Change from Prior Year” represent the ratio of (a) the difference between the current and prior year volume over (b) the prior year volume.

Billing and Payment Procedures. As servicer, GMACM collects and remits mortgage loan payments, responds to borrower inquiries, accounts for principal and interest, holds custodial and escrow funds for payment of property taxes and insurance premiums, counsels or otherwise works with delinquent borrowers, supervises foreclosures and property dispositions and generally administers the loans. GMACM sends monthly invoices or annual coupon books to borrowers to prompt the collection of the outstanding payments. Borrowers may elect for monthly payments to be deducted automatically from bank accounts on the same day every month or may take advantage of on demand ACH payments made over the internet or via phone. GMACM may, from time to time, outsource certain of its servicing functions, such as contacting delinquent borrowers, property tax administration and hazard insurance administration, although any such outsourcing will not relieve GMACM of any of its responsibilities or liabilities as a servicer.
