Report of Independent Auditors


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 ("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, 2004 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 entity's compliance based on our examination.


Our examination was made in accordance with 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 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
standards.


Our examination identified certain instances of non compliance with USAP
as it relates to Section I - Custodial Bank Accounts. Specifically, there
were bank accounts over the course of several months where the Company was
not in full compliance with USAP requirements as it related to the
preparation of custodial bank reconciliations within 45 calendar days of
cutoff as well as the resolution of reconciling items within 90 calendar
days of original identification. The Company remediated the issues related
to the preparation of custodial bank accounts reconciliations within 45
calendar days as of December 31, 2004. These instances of non compliance
as well as management's remediation status are more fully described in
management's assertion, which is set forth in Exhibit 1.



In our opinion, management's assertion that the Company complied with the
aforementioned standards except for the instances of non compliance related
to Section I - Custodial Bank Accounts as of and for the year ended
December 31, 2004 is fairly stated, in all material respects.

Assertion, that GreenPoint Mortgage Funding, Inc., a wholly owned subsidiary of

December 31, 2004. Management is responsible for GreenPoint Mortgage Funding,

servicing standards over mortgage payments as of and for the year ended

Lines of Credit were not adjusted at the appropriate date in accordance with
the mortgagor's loan documents. This resulted in the mortgagor being
overcharged for the period from the interest rate change until the correct
effective date, which was the first day of the following month.

In our opinion, except for the material noncompliance described in the third
paragraph, management's assertion that GreenPoint Mortgage Funding, Inc.

Exhibit 1


Management's Assertion Concerning Compliance
with USAP Minimum Servicing Standards


March 18, 2005

As of and for the year ended December 31, 2004, GMAC Mortgage Corporation
and its subsidiaries (the "Company") have complied in all material
respects with the minimum servicing standards (the "Standards") set forth
in the Mortgage Bankers Association of America's Uniform Single
Attestation Program for Mortgage Bankers ("USAP" except as follows:
Section I - Custodial Bank Accounts requires that reconciliations be
prepared on a monthly basis for all custodial bank accounts and related
bank clearing accounts. These reconciliations shall be prepared within
forty-five (45) calendar days after the cutoff date and reconciling items
resolved within ninety (90) calendar days of their original
identification.


Subsequent to the Company's servicing platform conversion that took place
in January of 2004, and as a result of temporary reporting challenges
resulting from this conversion, there were bank accounts over the course
of several months where the Company was not in full compliance with USAP
requirements as it related to the preparation of custodial bank
reconciliations within 45 calendar days of cutoff as well as the
resolution of reconciling items within 90 calendar days of original
identification.


The Company remediated the issues related to the preparation of custodial
bank accounts reconciliations within 45 calendar days as of December 31,
2004. The Company has subsequently, in 2005, remediated the resolution of
reconciling items within 90 calendar days of original identification.


As of and for this same period, the Company had in effect fidelity bond
and errors and omissions policies in the amounts of $300,000,000 and
$100,000,000, respectively.

Uniform Single Attestation Program for Mortgage Bankers, except for the
following:

  * In certain circumstances, the mortgage interest rate changes on certain Home
    Equity Lines of Credit were not adjusted at the appropriate date in
    accordance with the mortgagor's loan documents. This resulted in the
    mortgagor being overcharged for the period from the interest rate change
    until the correct effective date, which was the first day of the following
    month. This error was identified by Management and the systemic issue that
    caused the incorrect calculation of interest was resolved prior to the
    issuance of this letter.

As of and for the year ended December 31, 2004, the Company had in effect a
fidelity bond in the amount of $25,000,000 for a single loss limit and an
aggregate limit of liability of $50,000,000 and an errors and omissions policy
in the amount of $25,000,000 for a single loss limit and no aggregate limit of
liability.

Very truly yours,
