These classes can be exchanged for combinations of initial exchangeable certificates as specified in the offering documents.

Classes A-1, A-2, A-3, A-4, A-5, A-6, A-7, A-8, A-9, A-10, A-11, A-12, A-13, A-14, A-15, A-16, A-17, A-18, A-19, A-20, A-21, A-22, A-23, A-24, A-25, A-26, A-27, A-28, A-29, and A-30 certificates are super-senior certificates. These classes benefit from additional protection from the senior support certificates (Classes A-31, A-32, and A-33) with respect to loss allocation.

The AAA (sf) ratings on the Certificates reflect 5.05% of credit enhancement provided by subordinated certificates. The AA (sf), A (sf), BBB (sf), BB (sf), and B (sf) ratings reflect 3.30%, 2.05%, 1.00%, 0.60%, and 0.40% of credit enhancement, respectively.

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

This deal is a securitization of a portfolio of first-lien, fixed-rate prime residential mortgages funded by the issuance of the Certificates. The Certificates are backed by 469 loans with a total principal balance of $430,638,910 as of the Cut-Off Date (November 1, 2021).

Guaranteed Rate, Inc. (Guaranteed Rate), as the Sponsor, began issuing prime jumbo securitizations from its RATE shelf in early 2021 and this transaction represents the fourth prime jumbo RATE deal. The pool consists of fully amortizing fixed-rate mortgages with original terms to maturity of primarily 30 years and a weighted-average loan age of two months. Approximately 83.8% of the pool are traditional, nonagency, prime jumbo mortgage loans, which includes loans that were underwritten using an automated underwriting system (AUS) designated by Fannie Mae (56.3%) but may be ineligible for purchase by such agencies because of loan size. The remaining 16.2% of the pool are conforming mortgage loans that were underwritten using an agency AUS and were eligible for purchase by such agencies. Details on the underwriting of conforming loans can be found in the Key Probability of Default Drivers section of the related presale report.

All of the mortgage loans were originated by Guaranteed Rate. Guaranteed Rate is also the Servicing Administrator and Sponsor of the transaction. The loans will be serviced by ServiceMac, LLC. Wells Fargo Bank, N.A. (rated AA with a Negative trend by DBRS Morningstar) will act as the Master Servicer, Securities Administrator, and Certificate Registrar. Deutsche Bank National Trust Company will act as the Custodian. Wilmington Savings Fund Society, FSB will serve as Trustee.

Similar to the prior RATE securitizations, the Servicing Administrator will fund advances of delinquent principal and interest (P&I) on any mortgage until such loan becomes 120 days delinquent or such P&I advances are deemed to be unrecoverable by the Servicer or the Master Servicer (Stop-Advance Loan). The Servicing Administrator will also fund advances in respect of taxes, insurance premiums, and reasonable costs incurred in the course of servicing and disposing properties.

The interest entitlements for each class in this transaction are reduced reverse sequentially by the delinquent interest that would have accrued on the Stop-Advance Loans. In other words, investors are not entitled to any interest on such severely delinquent mortgages, unless such interest amounts are recovered. The delinquent interest recovery amounts, if any, will be distributed sequentially to the P&I certificates.

The transaction employs a senior-subordinate, shifting-interest cash flow structure that is enhanced from a pre-crisis structure.

The Sponsor will have the option, but not the obligation, to repurchase any mortgage loan that becomes 90 to 120 days delinquent under the Mortgage Bankers Association method at a price equal to par plus interest and unreimbursed servicing advance amounts, provided that such repurchases in aggregate do not exceed 10% of the total principal balance as of the Cut-Off Date.

CORONAVIRUS PANDEMIC IMPACT
The Coronavirus Disease (COVID-19) 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. DBRS Morningstar saw increases in delinquencies for many residential mortgage-backed securities (RMBS) asset classes, shortly after the onset of coronavirus.

Such mortgage delinquencies were mostly in the form of forbearance, which are generally short-term payment reliefs that may perform very differently from traditional delinquencies. At the onset of coronavirus, because the option to forbear mortgage payments was so widely available, it drove forbearance to a very high level. When the dust settled, coronavirus-induced forbearance in 2020 performed better than expected, thanks to government aid, low loan-to-value ratios, and good underwriting in the mortgage market in general. Across nearly all RMBS asset classes, delinquencies have been gradually trending down in recent months as forbearance periods come to an end for many borrowers.

As of the Cut-Off Date, there are no loans that are subject to an active coronavirus-related forbearance plan with the Servicer. For loans that enter into a coronavirus-related forbearance plan after the Cut-Off Date and prior to or on the Closing Date, the Sponsor will remove such loans from the mortgage pool and remit the aggregate stated principal balance plus one month of accrued net interest for such loans. Loans that enter into a coronavirus-related forbearance plan after the Closing Date will remain in the pool.

The ratings reflect transactional strengths that include high-quality credit attributes, well-qualified borrowers, structural enhancements, a satisfactory third-party due-diligence review, and 100% current loans.

The ratings reflect transactional challenges that include the representations and warranties framework, limited advances of delinquent P&I, and the Servicing Administrator’s financial capability.

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