                       Report of Independent Auditors


To the Board of Directors and Shareholder
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 with 90  calendar  days of original  identification.  The
Company  remediated  the issues  related to the  preparation  of custodial  bank
accounts  reconciliations  within 45 calendar  days 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 I.

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.

                                                                Exhibit I


                  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  conversation,  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  with 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 the 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.
