Item 4: Description of the due diligence performed

PRPM 2023-NQM1

(1) Type of assets that were reviewed.

Consolidated Analytics, Inc. (“Consolidated Analytics”) performed certain due diligence services (the “Review”) described below on 19 mortgage loans acquired by PRP-LB 2023-NQM1, LLC, through a bulk purchase. The Review was conducted from January 2022 through October 2022 on mortgage loans originated between November 2021 and October 2022.

(2) Sample size of the assets reviewed.

The Review consisted of a sample population of 19 loans with an aggregate principal balance of $7,172,200.50.

(3) Determination of the sample size and computation.

The sample population was determined and provided by Consolidated Analytics’ client (as identified by Item 2). The Review was conducted consistent with the criteria for the nationally recognized statistical rating organizations S&P and DBRS Morningstar, NRSRO(s), identified in Item 3 of the ABS Due Diligence-15E. Consolidated Analytics does not know the size of the overall securitization population and other third-party review (“TPR”) firms may have reviewed loans within the overall securitization population.

(4) Quality or integrity of information or data about the assets: review and methodology.

Consolidated Analytics compared data fields on the bid tape provided by the Client to the data found in the actual mortgage loan file as captured by Consolidated Analytics. This comparison, when data was available, included the following data fields:

Property Type	Origination Date	Original Appraised Value
Rate Lock Date	Original PI Payment	Borrower Last Name
Escrow Indicator	Loan Purpose	Loan Type
Maturity Date	Property Units	Occupancy
Orig Front End DTI	Original Note Rate	Original CLTV
Original LTV	Original Term	Sales Price
Orig Back End DTI	Property Address	Property City
Property State	Property Zip	UW FICO Utilized
AUS Type	Amortization Type	All Borrower Total Income
First Payment Date	Lien Position	Reserves
Original HOA Payment	Qualifying DSCR

(5) Origination of the assets and conformity to stated underwriting or credit extension guidelines, standards, criteria or other requirements: review and methodology.

Consolidated Analytics performed a “Credit Review” to verify compliance with guidelines in effect at the time of loan origination, or other guidelines provided by Client prior to review, and ensure the characteristics used by the underwriter are supported by the file documentation; and determine whether any loans outside of those guidelines contain legitimate and approved exceptions with compensating factors.

The Credit Review attempted to confirm the following:

(a) Credit Documentation: A review of the documentation underlying the credit decision was performed to determine sufficiency for consideration in the Credit Review. The Credit Documentation review consisted of the following:

o Loan Application: Complete loan application is present in the loan file for all borrowers/guarantors;

o Credit Report: Credit Report in file for all borrowers and meets guideline seasoning requirements and contains OFAC clearance;

o Income Documentation / Lease Agreements: Confirmation of the presence of income documentation in the loan file when required by lender or Client specified underwriting guidelines. For rental properties where existing leases are required to be verified, verify their presence and sufficiency for purpose based on underwriting guideline standards;

o Asset Documentation: Confirmation of presence of asset documentation requirements relative to loan type and guideline requirements for verification of closing funds and reserves;

o Borrower/Guarantor Identification: Verify that the file contains a copy of a government issued identification verification for each borrower (i.e. driver’s license, state ID, passport);

o Insurance Certificate: Verify that the loan file contains a copy of the hazard insurance certificate for the subject property and that flood insurance is also documented when required;

o Property Valuation: Confirm the presence of a complete appraisal report and supporting secondary independent estimate of value;

o Commercial Borrower Organizing Documentation: Confirm the presence an Operating Agreement, Bylaws, related amendments and filings or other organizing and operating documentation relative to the commercial borrower entity;

o Articles of Incorporation/Certificate of Formation: Confirm that each loan file contains a copy of the Articles of Incorporation establishing registration within the state of operation;

o Certificate of Good Standing: Confirm that each borrowing entity is active in the state of registration by confirming the presence of a web print out or certification of good standing for the state is in the file;

o Borrower Authority / Consent of Members: Confirm that the loan file contains evidence that the individual executing the loan agreements has been given signing authority on behalf of the borrowing entity.

(b) Legal Documentation: A review of the documentation required to secure the lender’s interest in the loan and the borrower(s)’ obligations thereunder was conducted with the purpose of validating their presence in the mortgage loan file and sufficiency of execution:

o Note/Loan Agreement/Security Instrument/Extension: Verification of the presence of the note, loan agreement or security instrument as applicable and that the agreement is properly executed by all parties. Confirm that all applicable allonges or addenda to the note are evidenced in the loan file and duly executed by all responsible parties. If the subject loan has reached or is nearing maturity confirm that an extension agreement is present and duly executed by all required parties;

o Mortgage/Deed of Trust/Assignment of Rents: Verify that a mortgage or deed of trust is in file and is duly executed and notarized and that it contains all applicable riders including an assignment of rents;

o Power of Attorney: If closing docs are executed by a POA confirm that the POA complies with all applicable underwriting and legal requirements including those for timing, form, authority and execution;

o Personal Guaranty: Verify that the requisite individual ownership percentage of a commercial entity borrower as stipulated within Client or lender underwriting guidelines has provided a personal guaranty for the loan;

o Affidavit of Commercial Purpose/Occupancy Certification: Verify that each file contains a borrower statement verifying that the loan is for commercial purpose and that the subject property will not be owner occupied;

o Title Policy: Confirmation that the file contains evidence of title insurance and that the title is free from material defects that could affect lien position;

o Deed for Conveyance of Title: Confirm that the applicable Grant or Warranty Deed is evidenced in the loan file and properly conveys interest in the subject property;

o Purchase Contract: If applicable, confirm the presence of a valid and executed Purchase and Sale Agreement along with any counter offers and modified terms of sale;

o Settlement Statement: As applicable based on loan type and origination date, confirm the presence of a final settlement statement in the mortgage loan file.

(c) Guidelines: The underwriting guidelines as specified by Client served as the criteria under which each loan qualification review took place. Qualification criteria includes:

o Borrower/Guarantor Eligibility: Review each borrower to ensure that they meet eligibility requirements of underwriting guidelines;

o Assets: Validate that the mortgage loan file contains adequately qualified verification of assets to meet underwriting standards;

o Debt-Service Coverage Ratios “DSCR”: Calculate the debt-service coverage ratio to ensure it meets minimum guideline standards;

o Credit History: Review the borrower credit reports and any supplemental credit history documentation to verify whether the borrower met guideline requirements;

o Credit Scores: Review each borrower/guarantor credit report to validate that the credit score used in qualification is accurate and whether it meets minimum loan qualification and underwriting standards as specified in the underwriting guidelines;

o Occupancy: Confirm that the occupancy of the subject property used for qualification of the loan is accurate and compliant with guideline requirements. Confirm that the borrower has executed an affidavit of commercial/business purpose and that no other documentation that shows the subject property might be a primary residence;

o Loan-to-Value Ratios: Recalculate the Loan-to-Value Ratio utilizing the Purchase Contract, Property Valuations and/or Loan Agreements to determine whether initial, as-is and as-repaired LTV and CLTV meet loan qualification and underwriting guideline standards based on the calculation methods set forth in underwriting guidelines;

o Insurance: Confirm the adequacy of hazard insurance coverage and that premiums are included in PITI calculations. If required based on flood zone, confirm the presence and adequacy of flood insurance coverage and that premiums are included in PITI calculations;

o Compensating Factors: Review and validate any compensating factors used in the qualification of the loan and in consideration of loan level underwriting guideline exceptions;

o Letters of Explanation: Confirm the presence of Letters of Explanation (LOX) where required per underwriting guidelines and that each such LOX adequately addresses the eligibility scenario under question;

o Exception Approvals: Confirm that any exceptions to underwriting guidelines and/or investor guideline overlays were fully documented, properly approved, and supported;

o Misrepresentation / Fraud Review: Validate that an independent third-party fraud report was obtained for each guarantor when required by underwriting guidelines and that red flags on third party fraud reports have been reviewed.

(6) Value of collateral securing the assets: review and methodology.

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

1.	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
2.	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.
3.	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.
4.	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.
5.	Review adjustments (line item, net and gross adjustments) to ensure they are reasonable.
6.	Review appraisal to ensure all required documents were included.
7.	Review location map provided within the appraisal for external obsolescence.
8.	Ensure highest and best use and zoning complies with guidelines.
9.	Confirm there are no marketability issues that affect the subject property.
10.	Ensure subject property does not suffer any functional obsolescence.
11.	Where applicable, determine if the file did not contain the appraisal or other valuation method and a review could not be performed.
12.	Additional valuation products were not required when the CU score provided was 2.5 or below. In the event the CU score was greater than 2.5, an additional valuation product was obtained to confirm value was supported within 10% tolerance. In some instances, CDA’s were ordered on loans that had an acceptable CU score based on guidance from the seller.

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 (19 loans in total):

One (1) loan had a Secondary Appraisal, zero (0) loans had AVMs, and eleven (11) loans had Desktop Reviews. Consolidated Analytics has independent access to the Desktop Reviews ordered by the Aggregator.

If a loan with an AVM or Desktop Review fell outside of a -10% tolerance, was inconclusive, or a PIW was present, then a Field Review, a Broker Price Opinion (BPO) along with a Reconciliation of the values or a 2nd Appraisal was completed. There was one (1) occurrence of this.

Zero (0) loans had a Field Review or BPO, and zero (0) loans had an Exterior Only Appraisal Review.

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

(7) Compliance of the originator of the assets with federal, state and local laws and regulations: review and methodology.

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 below, each as amended, restated and/or replaced from time to time. In relation to cash out refinances of investment property loans, documentation provided in the loan file will be reviewed only to validate the use of cash out proceeds for business purposes at the origination/consummation of the loan. In the event use of proceeds cannot be validated, or are deemed to be utilized for consumer purposes, the loan would then be subject to a “Compliance Review” of applicable regulatory requirements as noted below, each as amended, restated and/or replaced from time to time. The Compliance Review included the following:

a. Test Loan Estimate(s) for accuracy and completeness as well as timing requirements as required by TRID Regulations

b. Test Closing Disclosure(s) for accuracy and completeness as well as timing requirements as required by TRID Regulations

c. Tolerance Testing

i. Compare Loan Estimate and Closing Disclosures

ii. Identify Tolerance Violations and applicable cost to cure

d. Comprehensive review of Closing Disclosure to determine transaction accuracy

e. Recalculation of APR and Finance Charge

f. 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

iv. HOEPA Points and Fees

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

i. Service Provider List

ii. Home Ownership Counselling Disclosure

iii. ARM Disclosure

h. Compliance with QM as it relates to:

i. APR Test

ii. Points & Fees Test

iii. Prepayment Penalty Test

iv. Product Eligibility Testing

i. Notice of Right to Cancel (Rescission) Review

i. Confirm transaction date, expiration date, and disbursement date

ii. Confirm document is properly executed by all required parties to the transaction

iii. Confirm the correct Right of Rescission document was executed for the transaction type

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

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

l. 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.

(8) Other: review and methodology.
