Page 1 of 11

conformity to the applicable underwriting guidelines and other regulatory requirements described below, including (if applicable) the Ability to Repay and Qualified Mortgage requirements. Review areas included, but are not limited to:

Credit Review and Methodology

Credit Report: Analyzed the Borrower’s credit report/credit history, confirming that credit scores, liabilities and public records met guideline requirements. Liabilities gathered from the credit report were included in the re-calculation of the debt-to-income ratio as appropriate. In addition the following data was also captured and reviewed to confirm compliance with guideline and ASF reporting requirements: (i) credit report date, (ii) bankruptcy date, (iii) bankruptcy discharge date, (iv) bankruptcy chapter, (v) foreclosure date, (vi) short sell date, (vii) longest trade line (active), (viii) longest trade line balance (active), (ix) months reviewed, (x) number of trade lines, (xi) credit scores, (xii) revolving debts and (xiii) installments debts.

Loan Application (1003): Reviewed the Borrower’s Loan Application including comparison of initial loan application against the final loan application, or other loan applications found in the file, to identify potential discrepancies. In addition the following data was also captured and reviewed to confirm compliance with guideline and ASF reporting requirements: (i) purpose, (ii) years in primary residence, (iii) number of mortgaged properties (as compared with the credit reports disclosed mortgages), (iv) application date, (v) borrower information (name, date of birth, social security number and number of family members), (vi) borrower’s address, (vii) borrower(s)’ employment information (including address, years at job, years in field), (vii) monthly income and (ix) citizenship.

Loan Approval/Exception Form (if applicable): Reviewed the Lender’s approval and Client’s exception approval documentation to confirm appropriate risk mitigating factors were present when granting exceptions.

Sales Contract (if applicable): Reviewed the sales contract to confirm buyer(s) and seller(s), sales price and property address matches other documents.

Title: Reviewed the title policy or commitment to identify possible judgments or other liens that may have existed at origination. In addition, proper vesting and parties (as disclosed on sales contract, note, and deed) were reflected accurately.

Hazard and Flood Insurance: Reviewed hazard and flood (if applicable) insurance to ensure policy met the minimum required amount of replacement coverage.

Employment and Income (DTI Loans): Reviewed borrower(s)’ employment and income documentation used for qualification purposes and as applicable, Appendix Q or Ability to Repay, including recalculation of debt-to-income ratio (DTI) to confirm compliance with underwriting guidelines. Items reviewed included: (i) verbal or written verifications of employment, (ii) pay stubs, (iii) W-2’s, (iv) federal tax returns, (v) bank statements, (vi) profit and loss statements, and (vii) IRS tax transcripts (when provided).

Leases and Market Rents (DSCR Loans): Reviewed lease agreements and third-party market rent documents to confirm compliance with Debt-Service-Coverage-Ratio requirements. Note, the documentation that can be used to establish market rents can vary from lender to lender. CRES reviews the market rent source, to ensure compliance with applicable guidelines. In some cases, lenders may not require proof of market rents, if a sourced payment history can be provided along with the lease agreement.

Assets: Reviewed (i) bank statements, (ii) verification-of-deposit (VOD) and (iii) stock or security account statements to ensure adequate assets were provided verifying down payment, closing costs and reserves required by the guidelines and as applicable Appendix Q or Ability to Repay.

Page 2 of 11

Guidelines: Confirmed compliance with applicable underwriting guidelines and determined the qualification of credit and income, assets, property type and usage, LTV/CLTV, and documentation requirements to applicable underwriting guidelines and loan program matrices. Items included, but not limited to: FICO, housing history, bankruptcy and foreclosure seasoning, occupancy, credit grade, loan amounts (minimum and maximum), maximum cash out amount, reserves, residual income, minimum trade lines, debt to income and debt service coverage ratio requirements.

Unless otherwise stated in the Lender’s or Client’s guidelines, Fannie Mae guidelines prevail.

Property Valuation Review and Methodology

CRES reviewed the Appraisal for completeness and conformance to industry standards, including requirements set forth in Title XI of FIRREA. The review included both data and description information provided by the appraiser. Review items included: (i) property address and borrower information matches the mortgage note and other critical origination documents, (ii) neighborhood characteristics and housing trends were acceptable and met applicable underwriting guidelines, (iii) site information for zoning compliance and possible adverse site notations reviewed for adverse conditions, FEMA Flood Zone designation matched the Flood Certification, (iv) property type and property description information met applicable underwriting guidelines, (v) comparable sales (sale dates, distance, gross and net adjustments, square footage, and value) met industry standards and were properly bracketed, (vi) comparable size, style, and location were similar to the subject address, (vii) condition of the property was average or better and notable repairs were addressed, (viii) appraisal was made on an “as is” basis or proper evidence of completion was obtained and clearly documented and addressed all “subject to” conditions noted, (ix) subject and comparable photos reviewed to ensure appraisal description information coincides with property pictures and that no visible adverse issues are present that the appraiser did not address, (x) appraisal was completed by a licensed appraiser and (xi) appraisal was completed within the required timing requirements, as disclosed in the applicable underwriting guidelines.

A secondary enhanced desk review product, (such as an ARR from ProTeck or CDA from Clear Capital), from an approved AMC was required on all transactions. In lieu of an enhanced desk review product, a field review or second appraisal from a client approved AMC is acceptable. The source of the Appraisal Review Product may not be the same AMC used for the appraisal. If the Appraisal Review Product value is more than 10% below the appraised value, a second field review or appraisal was required. In certain cases, sellers may include an enhanced desk review product from a Client approved AMC. All ARR or CDA documentation provided by a client approved AMC vendor was recorded by CRES, as an acceptable valuation support option as long as valuations were obtained in accordance with guidelines and through notable AMC vendors. Any loans that did not maintain an enhanced desk review or did not meet the Client’s vendor requirements were conditioned and communicated with the Client.

For loans that did not maintain an acceptable enhanced desk review product, CRES ordered an Appraisal Risk Review (ARR) or Collateral Desktop Analysis (CDA) from various Appraisal Management Companies for valuation support. All loans outside of a 10% variance from the original appraised value were identified and communicated to the Client.

If material origination valuation discrepancies could not be resolved an exception was created and the applicable NRSROs valuation grade was recorded.

Compliance Review Methodology (Consumer Loans )

CRES reviews on 16 consumer loans included comprehensive audit of fees and disclosed federal, state,

Page 3 of 11

municipal requirements along with timing of delivery requirements for TRID related Loan Estimates (LE’s) and the Initial Closing Disclosure (CD’s). The reviews track delivery and receipt requirements for all LE’s and CD’s, tracks fee changes and changed circumstances affecting fees, provides a fee tolerance comparison across all LE’s and CD’s.

In addition to the TRID specific items, the loans were also subject to the following Pre-TRID and Post- TRID compliance testing. Note that the pool of loans contains some assets that are classified as “business purpose”. In such cases certain compliance TILA and Regulation Z requirements were not tested, as the law’s provisions do not apply to an extension of credit if primarily for business or a commercial purpose (12 C.F.R. §1026.3(a); 15 U.S.C. § 1603).

CRES utilizes a third party compliance company’s software for certain compliance tests. The following Pre-TRID, TRID, Qualified Mortgage (QM), and High Costs related test were completed within the third party compliance software:

In addition to the checks disclosed above, various state license-based consumer lending and licensing laws and regulations tests were also completed using the third-party compliance software.

This pool contains 30 loans that are classified as “business purpose”. In such cases compliance TILA and Regulation Z requirements were not tested, as the law’s provisions do not apply to an extension of credit if primarily for business or a commercial purpose (12 C.F.R. §1026.3(a); 15 U.S.C. § 1603).

General Ability to Repay

CRES reviews all loan transactions that are covered by the Ability to Repay rule as set forth in Regulation Z- Truth in Lending Act (TILA) to determine whether the lender considered and evaluated the eight underwriting factors. The eight factors reviewed are: (i) Current or reasonably expected income or assets (other than the value of the property that secures the loan) that the consumer will rely on to repay the loan, (ii) Current employment status (if you rely on employment income when assessing the consumer’s ability to repay), (iii) Projected monthly mortgage payment for this loan (calculated using the introductory or fully- indexed rate, whichever is higher, and monthly, fully-amortizing payments that are substantially equal), (iv) Projected monthly payment on any simultaneous loans secured by the same property, (v) Monthly payments for property taxes and insurance that you require the consumer to buy, and certain other costs related to the property such as homeowners association fees or ground rent, (vi) Debts, alimony, and child- support obligations, (vii) Monthly debt-to-income ratio or residual income, calculated using the total of all of the mortgage and non-mortgage obligations listed above, as a ratio of gross monthly income, and (viii) Credit history.

Qualified Mortgage

When applicable, CRES assessed the borrower(s)’ QM classification and re-assigns a due diligence reviewed QM or Non-QM type for each loan. Loans are classified into one of the following five categories:

(i) QM/Non-Higher Priced Mortgage Loan (safe harbor): Loans that meet the rule's definition of a QM and are eligible for safe harbor protection, (ii) QM/High Priced Mortgage Loan (rebuttable presumption): Loans that meet the rule's definition of a QM and are eligible for rebuttable presumption protection, (iii) Non-QM Compliant: Loans that do not meet the QM definition but fully comply with the ATR rule, (iv) Non- QM/Non-Compliant: Loans that do not meet the QM definition and do not comply with the ATR rule, and (v) Not Covered/Exempt: Loans that are not covered by the rule.

Note that CRES determines the mortgage loan’s status under the ATR or QM rule requirements and assigns a proper due diligence mortgage loan designation that is solely based on the documentation available at the time of the review. Classifications of QM and Non-QM are based on multiple factors including, but not limited to, requirements as set forth in Appendix Q to Part 1026.

The table below contains the TRID eligible breakdown for the loan population:

	Count	Percentage of Population
Investment/Business Purpose Loans	30	65.22%
Initial Application Date prior to October 3, 2015	0	0.00%

Tape Data Compare

CRES compared data fields on the data tape provided by the Client to the data points disclosed on the actual mortgage loan file documents, as captured by CRES. When data was available, the following data elements were compared:

Appraised Value	First Payment Date	Occupancy	Property Zip
CLTV	Interest Rate	Orig Term	Purpose
Doc Level	Lien Position	Original Balance	QM Type
DSCR	LTV	P&I Payment
DTI	Note Date	Property City
FICO	Note Type	Property State

The seller provided CRES with loan level data regarding the mortgage loans for the data integrity check. CRES received the data directly from the seller through a loan registrations system or via a data tape.

Of the 46 mortgage loans reviewed, twenty unique mortgage loans had at least one tape discrepancy across 21 data fields (some mortgage loans had more than one data discrepancy). The following table discloses the number of data discrepancies noted by field name. Note, data was not provided on certain field compare values. The fields in which tape data was not available is noted below; however, a data discrepancy was not counted if the seller failed to provide a compare value.

DTI Variance Threshold Applied: 3%

DTI variances are the difference on the percentage of income dedicated toward making debt payments. These variances occur frequently due to differences in calculating incomes. Total Debt Ratio variances that were less than or equal to 3% of the tape value are not included in the data discrepancies reflected.
