The Board of Directors
First Horizon Home Loan Corporation and Subsidiaries:

We have examined managements assertion, included in the accompanying
management assertion letter, that First Horizon Home Loan Corporation
and its wholly owned subsidiary, First Tennessee Mortgage Services, Inc.,
which includes a consolidated investment in FH-FF Mortgage Services, L.P.
(the Company), complied with the minimum servicing standards set forth 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, 2004.  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 conducted in accordance with the 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 specified above
and performing such other procedures as we considered necessary in the
circumstances.  We believe that our exmanination 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, 2004, is fairly stated, in all material respects.

        This includes both flood and hazard insurance.

4.	For those loans being escrowed for the payment of taxes and
        insurance, sufficient amounts are being collected monthly to
        provide for payment of future items.

5.	Property inspections have been completed according to the
        provisions of our servicing agreement, if applicable.

6.	All other provisions of the servicing agreements have been
