DBRS Morningstar Assigns Provisional Ratings to Chase Home Lending Mortgage Trust 2023-RPL1

DBRS, Inc. (DBRS Morningstar) assigned the following provisional ratings to the Mortgage Certificates, Series 2023-RPL1 (the Certificates) to be issued by Chase Home Lending Mortgage Trust 2023-RPL1 (CHASE 2023-RPL1 or the Trust):

-- $400.1 million Class A-1-A at AAA (sf)
-- $20.5 million Class A-1-B at AAA (sf)
-- $420.6 million Class A-1 at AAA (sf)
-- $24.3 million Class A-2 at AA (high) (sf)
-- $15.5 million Class M-1 at A (high) (sf)
-- $11.0 million Class M-2 at BBB (high) (sf)
-- $7.8 million Class B-1 at BBB (low) (sf)
-- $5.0 million Class B-2 at BB (sf)

The AAA (sf) rating on the Class A-1-A, Class A-1-B, and Class A-1 Certificates reflects 15.90% of credit enhancement, provided by subordinated notes in the transaction. The AA (high) (sf), A (high) (sf), BBB (high) (sf), BBB (low) (sf), and BB (sf) ratings reflect 11.05%, 7.95%, 5.75%, 4.20%, and 3.20% of credit enhancement, respectively.

Other than the classes specified above, DBRS Morningstar does not rate any other classes in this transaction.

This transaction is a securitization of a portfolio of primarily seasoned performing and reperforming first-lien residential mortgages and funded by the issuance of mortgage certificates (the Certificates). The Certificates are backed by 2,565 loans with a total principal balance of $526,395,515 as of the Cut-Off Date (March 31, 2023).

J.P. Morgan Mortgage Acquisition Corp. will serve as the Sponsor and Mortgage Loan Seller of the transaction. JPMorgan Chase Bank, National Association (JPMCB) will act as the Representing Party, Servicer, and Custodian. DBRS Morningstar rates JPMCB's Long-Term Issuer and Long-Term Senior Debt at AA with a stable trend and its Short-Term Instruments at R-1 (high) with a stable trend.

The loans are approximately 202 months seasoned on average. As of the Cut-Off Date, 99.5% of the pool is current under the Mortgage Bankers Association (MBA) delinquency method, and 0.5% is in bankruptcy. All the bankruptcy loans are currently performing. Approximately 97.6% and 91.4% of the mortgage loans have been zero times (x) 30 days delinquent for the past 12 months and 24 months, respectively, under the MBA delinquency method.

Within the portfolio, 98.4% of the loans are modified. The modifications happened more than two years ago for 99.1% of the modified loans. Within the pool, 949 mortgages have non-interest-bearing deferred amounts, which equate to 9.4% of the total principal balance. Unless specified otherwise, all statistics on the mortgage loans in the related report are based on the current balance, including the applicable non-interest-bearing deferred amounts.

One of the Sponsor's majority-owned affiliates will acquire and retain a 5% vertical interest in the transaction, consisting of an uncertificated interest in the issuing entity, to satisfy the credit risk retention requirements. Such uncertificated interest represents the right to receive at least 5% of the amounts collected on the mortgage loans (net of fees, expenses, and reimbursements).

There will not be any advancing of delinquent principal or interest on any mortgage by the Servicer or any other party to the transaction; however, the Servicer is generally obligated to make advances in respect of taxes and insurance as well as reasonable costs and expenses incurred in the course of servicing and disposing properties.

For this transaction, the servicing fee payable for the mortgage loans is composed of three separate components: the base servicing fee, the delinquent servicing fee, and the additional servicing fee. These fees vary based on the delinquency status of the related loan and will be paid from interest collections before distribution to the securities.

On any Distribution Date when the aggregate unpaid principal balance (UPB) of the mortgage loans is less than 10% of the aggregate Cut-Off Date UPB, the Servicer (and it's successors and assigns) will have the option to purchase all of the mortgage loans at a purchase price equal to the sum of the unpaid principal balance of the mortgage loans, accrued interest, the appraised value of the real estate owned properties, and any unpaid expenses and reimbursement amounts.

The transaction employs a sequential-pay cash flow structure. Principal proceeds can be used to cover interest shortfalls on the Certificates, but such shortfalls on Class M-1 and more subordinate bonds will not be paid from principal proceeds until Class A-1-A, Class A-1-B, and Class A-2 are retired.

The ratings reflect transactional strengths that include the following:
-- Credit quality relative to reperforming pools,
-- Seasoning,
-- Current delinquency status,
-- Satisfactory third-party due-diligence review,
-- Structural features, and
-- Representations and warranties standard.

The transaction also includes the following challenges:
-- No servicer advances of delinquent principal and interest, and
-- Assignments and endorsements.

The full description of the strengths, challenges, and mitigating factors is detailed in the related presale report.
