The review began on April 1, 2021, and concluded in April 30, 2021.

Scope of Review

• Determine representative credit score from credit report

b. Validate loan-to-value (LTV) and combined loan-to-value

e. Confirm sufficient evidence in loan file, by reviewing the underwriter’s decision to approve the loan based upon the borrows income, debt, and credit history, to support borrower's willingness and ability to repay the debt

f. Confirm that Final 1003 is sufficiently completed

g. Provide Audit 1008 with accurate data based on file documentation

h. Confirm Loan Approval conditions were met

i. Review condominium questionnaire to verify all information is complete, prepared by an authorized representative, and address any red flags that may deem condominium project ineligible

Compliance Review

Consolidated Analytics performed a “Compliance Review” to determine, as applicable, to the extent possible and subject to the caveats below, whether the loan complies with applicable regulatory requirements as noted blow, each as amended, restated and/or replaced from time to time.  The Compliance Review included the following:

a. Recalculation of APR and Finance Charge

b. Testing of:

i. Federal High Cost Mortgage provisions

ii. Federal Higher Priced Mortgage Loans provisions

iii. Local and/or State Anti-predatory and High Cost provisions

c. Determine whether specified federal disclosures were provided timely based upon comparison of the application date to the dates on such disclosures:

i. Right to Receive Copy of Appraisal

d. National Flood Insurance Program (NFIP) Review:

i. Adherence to flood insurance coverage

ii. Identification of flood zones

iii. Evidence of adequate coverage amounts

e. Fair Credit Reporting Act (FCRA)

g. Confirm through NMLS the loan originator and originating firm's license status was active and properly disclosed on appropriate loan documents

h. Check the Loan participants against the exclusionary list provided by Client or by the purchaser of the Loan(s)

i. Review closing documents to ensure that the Mortgage Loan information is complete, accurate, and consistent with other documents; Confirm collateral documents have been recorded or sent for recording

The Compliance Review did not include any federal, state or local laws, constitutional provisions, regulations or ordinances that are not expressly enumerated above.  Furthermore, the findings reached by Consolidated Analytics are dependent upon its receiving complete and accurate data regarding the loans from loan originators and other third parties upon which Consolidated Analytics is relying in reaching such findings.

Valuation Review

 Consolidated Analytics performed a “Valuation Review,” which included the following:

a. Review original appraisal, determination that property is in "average" condition or better, or property requires cosmetic improvements (as defined by the appraiser) that do not affect habitability. Should an area of concern be identified with the condition of the property, Consolidated Analytics will alert Client.

b. Review appraisal, determination that property is completely constructed and appraisal is on an “as is basis,” or property is identified as not completely constructed by originating appraiser.

c. Review and determine if the appraisal report was performed on appropriate GSE forms and if the appraiser indicated in the body of the subject appraisal that the appraisal conforms to USPAP standards.

d. Review and determine the relevance of the comparable properties and ensure that a rational and reliable value was provided and supported as of the effective date of the Origination Appraisal.

e. Review adjustments (line item, net and gross adjustments) to ensure they are reasonable.

f. Ensure that the appraisal conforms to the guidelines provided from the Client.

g. Review appraisal to ensure all required documents were included.

h. Review location map provided within the appraisal for external obsolescence.

i. Ensure highest and best use and zoning complies with guidelines.

j. Confirm there are no marketability issues that affect the subject property.

k. Ensure subject property does not suffer any functional obsolescence.

l. Where applicable, determine if the file did not contain the appraisal or other valuation method and a review could not be performed.

m. For loans with a PIW present in the loan file, 303 loans in total, original appraised values were provided by the client. A retroactive 2055 or documentation to substantiate the origination values as provided by the client was not present at the time of the review.

Consolidated Analytics applied a cascade methodology to determine if the original appraised value was reasonably supported when compared to an independent third-party valuation product.

For loans reviewed in a post-close valuation review scenario (242 loans in total):

98 loans had an Automated Valuation model which was performed by Collateral Analytics. Consolidated Analytics has independent access to the Desktop Reviews ordered by the Aggregator.

103 loans had Desktop Reviews which were performed by Consolidated Analytics (103 CCAs).

If a loan with a Desktop Review fell outside of a -10% tolerance or was inconclusive, then a Field Review, a Broker Price Opinion (BPO) along with a Reconciliation of the values or a 2nd Appraisal was completed.

0 loans had a Field Review of which zero Field Reviews did not support the value.

Product totals may not sum due to multiple products for each loan.

Of the 95 mortgage loans reviewed, one unique mortgage loans (by loan count) had a total of one different tape discrepancies across one data fields (some mortgage loans may have had more than one). A blank or zero value on the data tape when an actual value was captured by Consolidated Analytics was not treated as a data variance.

Exception Category Summary

The table below summarizes the individual exceptions which carried an associated “A”, “B”, “C”, or “D” level exception grade. One loan may have carried more than one exception. In such cases, the exception with the lowest grade would drive the loan grade for that particular area of the review. The overall loan grade is the lowest grade for any one particular review scope (ex. a loan with a Compliance Grade of “B”, a Credit Grade of “A”, and a Property Grade of “A” would receive an overall Loan Grade of “B”).
