DBRS Morningstar Assigns Rating to Citigroup Mortgage Loan Trust 2023-RP1

DBRS, Inc. (DBRS Morningstar) assigned a rating to the following Mortgage-Backed Notes, Series 2023-RP1 (the Notes) issued by Citigroup Mortgage Loan Trust 2023-RP1 (the Trust):

-- $974.7 million Class A-1 at AAA (sf)

The AAA (sf) rating on the Class A-1 Notes reflects 26.00% of credit enhancement provided by subordinated Notes.

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

This transaction is a securitization of a portfolio of seasoned performing and reperforming first-lien residential mortgages funded by the issuance of the Notes.

The Notes are backed by 6,826 loans with a total principal balance of $1,317,131,204 as of the Cut-Off Date (January 31, 2023).

The mortgage loans are approximately 144 months seasoned. As of the Cut-Off Date, 97.1% of the loans are current (including 0.8% bankruptcy-performing loans) and 2.9% of the loans are 30 days delinquent under the Mortgage Bankers Association (MBA) delinquency method. Under the MBA delinquency method, 19.3% and 60.8% of the mortgage loans have been zero times 30 days delinquent for the past 24 months and 12 months, respectively.

The portfolio contains 96.5% modified loans as determined by the Issuer. For purposes of this report, DBRS Morningstar did not consider deferrals or forbearance because of a Coronavirus Disease (COVID-19) pandemic-related hardship as modifications. As such, DBRS Morningstar considered 88.5% of the pool to have been modified. The modifications happened more than two years ago for 29.7% of the loans that DBRS Morningstar classified as modified. Within the pool, 2,205 mortgages have an aggregate non-interest-bearing deferred amount of $84,823,685, which comprises 6.4% of the total principal balance.

The Seller, Citigroup Global Markets Realty Corp. (CGMRC), acquired the mortgage loans through bulk whole loan acquisitions. The Seller will then contribute the loans to the Trust through an affiliate, Citigroup Mortgage Loan Trust Inc. (the Depositor). As the Sponsor, CGMRC or one of its majority-owned affiliates will acquire and retain a 5% eligible vertical interest in each class of Notes (other than the Class R Notes) to satisfy the credit risk retention requirements. The loans were originated and previously serviced by various entities.

Newrez LLC doing business as Shellpoint Mortgage Servicing will be the Servicer of the loans. There will not be any advancing of delinquent principal and interest (P&I) on any mortgages by the Servicer or any other party to the transaction; however, the Servicer is obligated to make advances in respect of homeowner's association fees in super lien states and, in certain cases, taxes and insurance as well as reasonable costs and expenses incurred in the course of servicing and disposing of properties.

When the aggregate pool balance is reduced to less than 25% of the balance as of the Cut-Off Date, the directing noteholder may purchase all of the mortgage loans and real estate owned properties from the Issuer, as long as the aggregate proceeds meet a minimum price that meets or exceeds par plus interest.

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

The transaction assumptions consider DBRS Morningstar’s baseline macroeconomic scenarios for rated sovereign economies, available in its commentary, “Baseline Macroeconomic Scenarios for Rated Sovereigns: December 2022 Update,” published December 21, 2022. These baseline macroeconomic scenarios replace DBRS Morningstar’s moderate and adverse coronavirus pandemic scenarios, which were first published in April 2020.

The ratings reflect transactional strengths that include the following:
-- Loan-to-value ratios;
-- Satisfactory third-party due-diligence review;
-- Representations and warranties provider;
-- Seasoning; and
-- Structural features.

The transaction also includes the following challenges:
-- Representations and warranties standard;
-- No servicer advances of delinquent P&I;
-- Assignments and endorsements; and
-- Borrowers on forbearance plans.

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