DBRS Morningstar Assigns Provisional Ratings to MFA 2023-INV1 Trust

February 07, 2023

DBRS, Inc. (DBRS Morningstar) assigned provisional ratings to the following Mortgage Pass-Through Certificates, Series 2023-INV1 (the Certificates) to be issued by MFA 2023-INV1 Trust (MFA 2023-INV1):

-- $108.9 million Class A-1 at AAA (sf)
-- $21.9 million Class A-2 at AA (high) (sf)
-- $23.2 million Class A-3 at A (high) (sf)
-- $14.3 million Class M-1 at BBB (high) (sf)
-- $12.2 million Class B-1 at BB (high) (sf)
-- $9.0 million Class B-2 at B (high) (sf)

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

The AAA (sf) rating on the Class A-1 certificates reflects 46.60% of credit enhancement provided by subordinate certificates. The AA (high) (sf), A (high) (sf), BBB (high) (sf), BB (high) (sf), and B (high) (sf) ratings reflect 35.85%, 24.45%, 17.40%, 11.40%, and 7.00% of credit enhancement, respectively.

This is a securitization of a portfolio of fixed- and adjustable-rate (including loans with initial Interest-Only (IO) period) investor debt service coverage ratio (DSCR), first-lien residential mortgages funded by the issuance of the Certificates. The Certificates are backed by 788 mortgage loans with a total principal balance of $203,853,952 as of the Cut-Off Date (December 31, 2022).

The originator of the loans in the mortgage pool is Lima One Capital, LLC (Lima One; 100.0%). Lima One will service the loans within the pool as of the Closing Date. MFA Financial, Inc. (MFA) is the Sponsor and the Servicing Administrator of the transaction.

The mortgage loans were underwritten to program guidelines for business-purpose loans that are designed to rely on property value, the mortgagor’s credit profile, and the DSCR, where applicable. Since the loans were made to investors for business purposes, they are exempt from the Consumer Financial Protection Bureau’s Ability-to-Repay rules and the TILA/RESPA Integrated Disclosure rule.

The Sponsor and Servicing Administrator are the same entity, and the Depositor is its affiliate. The initial Controlling Holder is expected to be the Depositor. The Depositor will retain an eligible horizontal interest consisting of a portion of Class B-2, and all of Class B-3 and XS Certificates representing at least 5% of the aggregate fair value of the Certificates to satisfy the credit risk-retention requirements under Section 15G of the Securities Exchange Act of 1934 and the regulations promulgated thereunder. Such retention aligns Sponsor and investor interest in the capital structure. Additionally, the Depositor will initially own the Class M-1, Class B-1, and the portion of the Class B-2 not required to be held as noted above.

Computershare Trust Company, N.A. (Computershare; rated BBB with a Stable trend by DBRS Morningstar) will act as the Securities Administrator and Certificate Registrar. Computershare, Deutsche Bank National Trust Company, and Wilmington Trust, National Association will act as the Custodians.

On or after the earlier of (1) the third anniversary of the Closing Date or (2) the date when the aggregate unpaid principal balance (UPB) of the mortgage loans is reduced to 30% of the Cut-Off Date balance, the Depositor, at its option, may redeem all of the outstanding Certificates at a price equal to the class balances of the related Certificates plus accrued and unpaid interest, including any Cap Carryover Amounts, and any non-interest bearing deferred amounts due to the Class XS Certificates (optional redemption). After such purchase, the Depositor may complete a qualified liquidation, which requires (1) a complete liquidation of assets within the trust and (2) proceeds to be distributed to the appropriate holders of regular or residual interests.

On any date following the date on which the aggregate UPB of the mortgage loans is less than or equal to 10% of the Cut-Off Date balance, the Servicing Administrator will have the option to terminate the transaction by purchasing all of the mortgage loans and any real estate owned (REO) property from the Issuer at a price equal to the sum of the aggregate UPB of the mortgage loans (other than any REO property) plus accrued interest thereon, the lesser of the fair market value of any REO property and the stated principal balance of the related loan, and any outstanding and unreimbursed servicing advances, accrued and unpaid fees, any non-interest bearing deferred amounts, and expenses that are payable or reimbursable to the transaction parties (optional termination). An optional termination is conducted as a qualified liquidation.

For this transaction, the Servicer or any other transaction party will not fund advances on delinquent principal and interest (P&I) on any mortgage. However, the Servicer is obligated to make advances in respect of taxes, insurance premiums, and reasonable costs incurred in the course of servicing and disposing of properties (servicing advances).

The transaction employs a sequential-pay cash flow structure with a pro rata principal distribution among the Class A-1, A-2, and A-3 Certificates (Senior Classes) subject to certain performance triggers related to cumulative losses or delinquencies exceeding a specified threshold (Trigger Event). Principal proceeds can be used to cover interest shortfalls on the Class A-1 and Class A-2 Certificates (IIPP) before being applied sequentially to amortize the balances of the senior and subordinated bonds after a Trigger Event has occurred. For the Class A-3 Certificates (only after a Trigger Event) and for the mezzanine and subordinate classes of Certificates (both before and after a Trigger Event), principal proceeds will be available to cover interest shortfalls only after the more senior classes have been paid off in full. Also, excess spread if available can be used to cover (1) realized losses and (2) cumulative applied realized loss amounts preceding the allocation of funds to unpaid Cap Carryover Amounts due to Class A-1 down to Class M-1.

Of note, the Class A-1, A-2, and A-3 Certificates' coupon rates step up by 100 basis points on and after the payment date in February 2027. Of note, interest and principal otherwise available to pay the Class B-3 interest and principal may be used to pay the Cap Carryover Amounts.

The transaction assumptions consider DBRS Morningstar's baseline macroeconomic scenarios for rated sovereign economics, available in its commentary “Baseline Macroeconomic Scenarios for Rated Sovereigns: December 2022 Update,” dated December 21, 2022. These baseline macroeconomic scenarios replace DBRS Morningstar's moderate and adverse Coronavirus Disease (COVID-19) pandemic scenarios, which were first published in April 2020.

The ratings reflect transactional strengths that include the following:

-- Improved underwriting standards,

-- Satisfactory third-party due-diligence review, and
