Re:

Sample Mortgage Loan Agreed-Upon Procedures


We have performed the procedures enumerated in Attachment A, which were agreed to and acknowledged as appropriate by Double Diamond, Inc. (“Double Diamond”) and the Issuer (together, the “Specified Parties”), for the intended purpose of assisting the Specified Parties in evaluating the accuracy of certain information with respect to a pool of mortgage loans contributed and sold to the Issuer which represent monies borrowed by persons to purchase underdeveloped lots of certain real estate developments (the “Mortgage Loans”) relating to the Issuer’s securitization transaction.  This report may not be suitable for any other purpose.  The procedures performed may not address all of the items of interest to a user of the report and may not meet the needs of all users of the report and, as such, users are responsible for determining whether the procedures performed are appropriate for their purposes.  The appropriateness of these procedures is solely the responsibility of the Specified Parties identified in this report.  No other party acknowledged the appropriateness of the procedures.  Consequently, we make no representation regarding the appropriateness of the procedures described in Attachment A, either for the purpose for which this report has been requested or for any other purpose.

The procedures performed and our associated findings are included in Attachment A.

The procedures included in Attachment A were limited to comparing or recalculating certain information that is further described in Attachment A.  The Issuer is responsible for the Subject Matter, Provided Data Files, Source Documents, Sample Characteristics and the determination of the instructions, assumptions and methodologies that are described herein.  We were not requested to perform, and we have not performed, any procedures other than those listed in Attachment A.  We have not verified, and we make no representation as to, the accuracy, completeness or reasonableness of the Provided Data Files, Source Documents or any other information provided to us, or that we were instructed to obtain, as applicable, by Double Diamond, on behalf of the Issuer, upon which we relied in forming our findings.  Accordingly, we make no representation and express no opinion or conclusion as to (a) the existence of the Mortgage Loans, (b) questions of legal or tax interpretation or (c) the appropriateness, accuracy, completeness or reasonableness of any instructions, assumptions and methodologies provided to us by Double Diamond, on behalf of the Issuer, that are described in this report.  We undertake no responsibility to update this report for events and circumstances occurring after the date hereof.

This agreed-upon procedures engagement was conducted in accordance with attestation standards established by the American Institute of Certified Public Accountants (the “AICPA”).  An agreed-upon procedures engagement involves the practitioner performing specific procedures that the Specified Parties have agreed to and acknowledged to be appropriate for the purpose of the engagement and reporting on findings based on the procedures performed.  We were not engaged to, and did not, conduct an examination to express an opinion or a review to express a conclusion in accordance with attestation standards established by the AICPA on any of the items referred to herein.  Accordingly, we do not express such an opinion or conclusion.  Had we performed additional procedures, other matters might have come to our attention that would have been reported to you.

The agreed-upon procedures described in this report were not performed for the purpose of:
a.
Satisfying any criteria for due diligence published by a nationally recognized statistical rating organization (a “rating agency”) or
b.
Making any findings with respect to:

iii.
Whether the originator(s) of the Mortgage Loans complied with federal, state or local laws or regulations or

Procedures performed and our associated findings

1.
As instructed by Double Diamond, on behalf of the Issuer, we randomly selected a sample of 75 Mortgage Loans from the Initial Data File (the “Sample Mortgage Loans”).  For the purpose of this procedure, Double Diamond, on behalf of the Issuer, did not inform us as to the basis for how they determined the number of Sample Mortgage Loans or the methodology they instructed us to use to select the Sample Mortgage Loans from the Initial Data File.

For the purpose of the procedures described in this report, the 75 Sample Mortgage Loans are referred to as Sample Mortgage Loan Numbers 1 through 75.

2.
For each Mortgage Loan on the Initial Data File and the Preliminary Data File, we compared the Account Number, as shown on the Initial Data File to the corresponding Account Number, as shown on the Initial Data File, and noted that:

a.
All of the Mortgage Loans included on the Initial Data File were included on the Preliminary Data File and

b.
There were no Mortgage Loans included on Preliminary Data File the were not included on the Initial Data File.

3.
As instructed by Double Diamond, on behalf of the Issuer, we appended the information for each Mortgage Loan on the Preliminary Data File with the corresponding Loan to Value information, as shown on the Updated Preliminary Data File.  The Preliminary Data File, as adjusted, is hereinafter referred to as the “Data File.”

4.
For each Sample Mortgage Loan, we compared the Sample Characteristics listed on Exhibit 1 to Attachment A, as shown on the Data File, to the corresponding information located in, or to the corresponding information we recalculated using information located in, the Source Documents or Data File, as applicable, subject to the instructions, assumptions and methodologies provided by Double Diamond, on behalf of the Issuer, described in the notes to Exhibit 1 to Attachment A.  The Source Document(s) that we were instructed by Double Diamond, on behalf of the Issuer, to use for each Sample Characteristic are shown on Exhibit 1 to Attachment A.  Except for the information shown on Exhibit 2 to Attachment A, all such compared information was found to be in agreement.

iv.
For the purpose of comparing the current rate Sample Characteristic for each Sample Mortgage Loan (except for the Sample Mortgage Loans described in the succeeding paragraph(s) of this note), Double Diamond, on behalf of the Issuer, instructed us to use the initial rate, as shown in the Contract.

For the purpose of comparing the current rate Sample Characteristic for each Sample Mortgage Loan with a step up date on or prior to the Cut-Off Date, as shown in the Contract, Double Diamond, on behalf of the Issuer, instructed us to use the step up rate, as shown in the Contract.

vi.
For the purpose of comparing the total number of payments Sample Characteristic for each Sample Mortgage Loan (except for the Sample Mortgage Loans described in the succeeding paragraph(s) of this note), Double Diamond, on behalf of the Issuer, instructed us to use the total number of payments, as shown in the Contract.

For the purpose of comparing the total number of payments Sample Characteristic for each Sample Mortgage Loan with a step up rate, as shown in the Contract, Double Diamond, on behalf of the Issuer, instructed us to recalculate the total number of payments as the sum of the:

a.
Number of payments at the initial rate and

b.
Number of payments at the step up rate,
both as shown in the Contract.

vii.
Double Diamond, on behalf of the Issuer, indicated that certain of the System Screen Shots contained account activity that occurred after the Cut-Off Date.  For the purpose of comparing the indicated Sample Characteristics for each Sample Mortgage Loan, Double Diamond, on behalf of the Issuer, instructed us to only consider account activity shown in the System Screen Shots that occurred on or prior to the Cut-Off Date.

For the purpose of comparing the original loan-to-value ratio Sample Characteristic for each Sample Mortgage Loan, Double Diamond, on behalf of the Issuer, instructed us to recalculate the original loan-to-value ratio by:

b.
Subtracting the down payment, as shown on the Data File, from the result obtained in a. above,

c.
Dividing the result obtained in b. above by the sum of the purchase price and sales tax, both as shown on the Data File, and

Rounding the result obtained in c. above to the second decimal (XX.XX%).

ix.
For the purpose of comparing the maturity date Sample Characteristic for each Sample Mortgage Loan, Double Diamond, on behalf of the Issuer, instructed us to recalculate the maturity date by:

a.
Adding the total number of payments, as shown in the Contract, to the prior extensions, as shown on the Data File,

Subtracting one from the result obtained in a. above and

c.
Adding the result obtained in b. above (in months) to the first payment date, as shown in the Contract.

x.
For the purpose of comparing the remaining term Sample Characteristic for each Sample Mortgage Loan, Double Diamond, on behalf of the Issuer, instructed us to recalculate the remaining term by subtracting the:

(and in accordance with any other applicable note(s)).
