All trends are Stable.

The rating confirmations reflect the overall stable performance of the transaction since the last rating action in November 2022. There are increased risks for a few loans, including one loan, representing 1.1% of the pool balance, that recently transferred to special servicing; however, servicer-reported performance metrics for the majority of the pool have been strong, evidenced by the pool’s healthy weighted average (WA) debt service coverage ratio (DSCR) of 1.97 times (x). In addition, the increased risk profile for the loans of concern is mitigated by the majority of the loans being secured by lodging and retail property types, which account for more than half of the pool balance, that have reported improved performance metrics over the last several months, demonstrating continued improvement and stabilization since the onset of the Coronavirus Disease (COVID-19) pandemic.

The pool is concentrated by property type, with hotel, retail, and office representing 30.1%, 30.3%, and 22.0% of the pool balance, respectively. While DBRS Morningstar anticipates upward pressure on vacancy rates in the broader office market, the majority of the loans secured by office properties have reported healthy performance metrics, demonstrated by the WA DSCR of 2.64x as of YE2022. In the analysis for this review, DBRS Morningstar identified nine loans representing 14.8% of the pool as exhibiting declines in performance and/or demonstrating increased risks from issuance. These loans were analyzed with stressed loan-to-value ratios or increased probability of default assumptions to increase the expected losses as applicable. The primary drivers behind DBRS Morningstar’s expected losses for the pool are cash flow declines for both retail and hospitality properties, generally related to the effects of the pandemic.

As of August 2023 remittance, all of the original 47 fixed-rate loans secured by 96 commercial and multifamily properties remain in the pool with a trust balance of $772.6 million, representing a collateral reduction of approximately 1.9% since issuance as a result of scheduled loan amortization. Two loans, representing 1.5% of the pool balance, are secured by defeased collateral. Two loans, representing 5.5% of the trust balance, are in special servicing, and an additional 13 loans, representing 34.0% of the trust balance, on the servicer’s watchlist.

The largest specially serviced loan, Santa Fe Portfolio (Prospectus ID#6; 4.4% of the pool), is secured by an 11-property mixed-use portfolio totaling approximately 218,000 square feet, located primarily in downtown Santa Fe, New Mexico. The portfolio has a high concentration of art gallery tenants, many of which are affiliates of the sponsor. The loan transferred to special servicing in August 2022 after becoming delinquent. The loan had previously transferred to special servicing in June 2020, also for payment default, and was modified in June 2021. The portfolio was performing below issuance expectations prior to the onset of the pandemic, compounding the risks of an extended delinquency. An updated December 2022 appraisal valued the property at $43.4 million, reflecting a slight value decline from the August 2020 appraisal of $44.5 million, and a variance of -17.5% from the issuance figure. While the loan is full recourse to the guarantor, the servicer commentary indicates the sponsor has not been in compliance with the modification agreement. However, the most recent value suggests a loss in the event of a liquidation would be relatively small.

At issuance, DBRS Morningstar shadow-rated two loans, 3 Columbus Circle (Prospectus ID#1; 6.5% of the pool) and 787 Eleventh Avenue (Prospectus ID#9; 3.9% of the pool), investment grade, supported by their strong credit metrics, strong sponsorship strength, and historically stable collateral performance. With this review, DBRS Morningstar confirms that the characteristics of these loans remain consistent with the investment-grade shadow rating.
