DBRS Morningstar Assigns Ratings to GS Mortgage-Backed Securities Trust 2022-RPL3

DBRS, Inc. (DBRS Morningstar) assigned ratings to the Mortgaged-Backed Securities, Series 2022-RPL3 (the Notes) issued by GS Mortgage-Backed Securities Trust 2022-RPL3 (GSMBS 2022-RPL3 or the Trust), as follows:

-- $967.8 million Class A-1 at AAA (sf)
-- $37.3 million Class A-2 at AA (sf)
-- $1.0 billion Class A-3 at AA (sf)
-- $1.0 billion Class A-4 at A (sf)
-- $1.0 billion Class A-5 at BBB (sf)
-- $24.3 million Class M-1 at A (sf)
-- $15.1 million Class M-2 at BBB (sf)
-- $9.7 million Class B-1 at BB (sf)
-- $9.7 million Class B-2 at B (sf)

The Class A-3, A-4, and A-5 Notes are exchangeable. These classes can be exchanged for combinations of initial exchangeable notes as specified in the offering documents.

The AAA (sf) ratings on the Notes reflect 10.55% of credit enhancement provided by subordinated notes. The AA (sf), A (sf), BBB (sf), BB (sf), and B (sf) ratings reflect 7.10%, 4.85%, 3.45%, 2.55%, and 1.65% of credit enhancement, respectively.

Other than the specified classes 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, primarily first-lien residential mortgages funded by the issuance of mortgage-backed notes (the Notes). The Notes are backed by 7,143 loans with a total principal balance of $1,138,897,045 as of the Cut-Off Date (June 30, 2022).

The portfolio is approximately 192 months seasoned and contains 70.5% modified loans. The modifications happened more than two years ago for 67.1% of the modified loans. Within the pool, 1,545 mortgages have non-interest-bearing deferred amounts, which equate to approximately 2.0% of the total principal balance. There are no Government-Sponsored Enterprise (GSE) Home Affordable Modification Program (HAMP) and proprietary principal forgiveness amounts included in the deferred amounts.

As of the Cut-Off Date, 99.3% of the loans in the pool are current. Approximately 0.7% of the pool are 30 days delinquent and five loans are 60 days delinquent under the Mortgage Bankers Association (MBA) delinquency method. Approximately 0.1% are in bankruptcy. (All bankruptcy loans are performing.) Approximately 85.0% of the mortgage loans have been zero times 30 days delinquent (0 x 30) for at least the past 24 months under the MBA delinquency method.

The majority of the pool (99.6%) is exempt from the Consumer Financial Protection Bureau (CFPB) Ability-to-Repay (ATR)/Qualified Mortgage (QM) rules because the loans were originated prior to January 10, 2014, the date on which the rules became applicable. The loans subject to the ATR rules are designated as Non-QM (0.4%).

The Mortgage Loan Sellers, Goldman Sachs Mortgage Company (GSMC; 99.8%) and MCLP Asset Company, Inc. (MCLP; 0.2%), acquired the mortgage loans in various transactions prior to the Closing Date from various mortgage loan sellers or from an affiliate. GS Mortgage Securities Corp. (the Depositor) will contribute the loans to the Trust. These loans were originated and previously serviced by various entities through purchases in the secondary market.

The Sponsor, GSMC, or a majority-owned affiliate will retain an eligible vertical interest in the transaction consisting of an uncertificated interest (the Retained Interest) in the Trust representing the right to receive at least 5.0% of the amounts collected on the mortgage loans, net of the Trust's fees, expenses, and reimbursements and paid on the Notes (other than the Class R Notes) and the Retained Interest to satisfy the credit risk retention requirements under Section 15G of the Securities Exchange Act of 1934 and the regulations promulgated thereunder.

As of the servicing transfer date (August 1, 2022), the mortgage loans will be serviced by Select Portfolio Servicing, Inc. (SPS; 86.5%) and NewRez LLC d/b/a Shellpoint Mortgage Servicing (SMS; 13.5%).

Unlike previous transactions from the GSMBS RPL shelf, which have a fixed aggregate servicing fee rate percentage, the servicing fee payable for GSMBS 2022-RPL3 will be calculated using a dollar servicing fee construct. The monthly servicing fee charged per loan will be determined based on the delinquency status of each mortgage loan. In its analysis, DBRS Morningstar assumed an fixed aggregate servicing fee rate higher than suggested by the dollar servicing fee construct.

There will not be any advancing of delinquent principal or interest on any mortgages by the Servicers or any other party to the transaction; however, the Servicers are obligated to make advances with respect to the preservation, inspection, restoration, protection, and repair of a mortgaged property, which includes delinquent tax and insurance payments, the enforcement or judicial proceedings associated with a mortgage loan, and the management and liquidation of properties (to the extent that the Servicer deems such advances recoverable).

When the aggregate pool balance of the mortgage loans is reduced to less than 25% of the Cut-Off Date balance, the Controlling Noteholder will have the option to purchase all remaining loans and other property of the Issuer at a specified minimum price. The Controlling Noteholder will be the beneficial owner of more than 50% the Class B-5 Notes (if no longer outstanding the next most subordinate Class of Notes, other than Class X).

As a loss mitigation alternative, the Controlling Noteholder may direct the Servicers to sell mortgage loans that are in an early or advanced stage of default or for which foreclosure or default is imminent to unaffiliated third-party investors in the secondary whole loan market on arms-length terms and at fair market value to maximize proceeds on such loans on a net present value basis.

The transaction employs a sequential-pay cash flow structure. Principal proceeds and excess interest can be used to cover interest shortfalls on the Notes, but such shortfalls on the Class M-1 Notes and more subordinate bonds will not be paid from principal proceeds until the more senior classes are retired. Excess interest can be used to amortize the principal of the notes after paying transaction parties' fees, Net Weighted-Average Coupon (WAC) shortfalls, and making deposits on to the breach reserve account.
CORONAVIRUS DISEASE (COVID-19) IMPACT
The pandemic and the resulting isolation measures have caused an immediate economic contraction, leading to sharp increases in unemployment rates and income reductions for many consumers. Shortly after the onset of the pandemic, DBRS Morningstar saw an increase in delinquencies for many residential mortgage-backed securities (RMBS) asset classes.

Such mortgage delinquencies were mostly in the form of forbearances, which are generally short-term periods of payment relief that may perform very differently from traditional delinquencies. At the onset of the pandemic, the option to forbear mortgage payments was widely available, driving forbearances to an elevated level. When the dust settled, loans with coronavirus-induced forbearance in 2020 performed better than expected, thanks to government aid, low loan-to-value ratios (LTVs), and acceptable underwriting in the mortgage market in general. Across nearly all RMBS asset classes, delinquencies have been gradually trending downward, as forbearance periods come to an end for many borrowers.

As of the Cut-Off Date, there are 38 loans (0.6% of unpaid principal balance) that are subject to an active coronavirus-related forbearance plan with the servicers.
