Report of Independent Auditors


To the Board of Directors and Stockholder
of Chase Home Finance LLC:


We have examined management's assertion about Chase Home Finance LLC's (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 made 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.
