Report of Independent Accountants




To the Board of Directors and Stockholder
of GMAC Mortgage Corporation:

We have examined management's assertion about GMAC Mortgage Corporation and its
subsidiaries (the "Company") compliance with the minimum servicing standards
identified in the Mortgage Bankers Association of America's Uniform Single
Attestation Program for Mortgage Bankers ("USAP") as of and for the year ended
December 31, 2005 included in the accompanying management assertion (see Exhibit
I).  Management is responsible for the Company's compliance with those minimum
servicing standards.  Our responsibility is to express an opinion on
management's assertion about the Company's compliance based on our examination.

Our examination was performed in accordance with attestation standards
established by the American Institute of Certified Public Accountants and,
accordingly, included examining, on a test basis, evidence about the Company's
compliance with the minimum servicing standards and performing such other
procedures as we considered necessary in the circumstances.  We believe that our
examination provides a reasonable basis for our opinion.  Our examination does
not provide a legal determination on the Company's compliance with the minimum
servicing standards.

In our opinion, management's assertion that the Company complied with the
aforementioned minimum servicing standards as of and for the year ended December
31, 2005 is fairly stated, in all material respects.
