The affirmations include 82 classes from 11 FREMF multifamily mortgage pass-through certificates and 54 classes from 11 Freddie Mac structured pass-through certificates.

Of the affirmed classes, the Rating Outlooks on 10 classes of FREMF mortgage pass-through certificates were revised to Positive from Stable.

KEY RATING DRIVERS

Freddie Mac Guarantee, Credit Linked Notes: The multifamily mortgage pass-through certificates are guaranteed by Freddie Mac. On July 11, 2022, Fitch affirmed Freddie Mac's Long-Term Issuer Default Rating (IDR) at 'AAA' and revised the Rating Outlook to Stable from Negative. This action followed Fitch's affirmation of the U.S. sovereign's 'AAA' IDR with a Stable Outlook on July 8, 2022.

The affirmations of the long-term ratings are based on the generally stable to improving pool performance and loss expectations, and are supported by the guarantee. Although the interest-only classes are guaranteed, the long-term ratings are based on the pass-through to the referenced certificates. Although Freddie Mac does not guarantee the structured pass-through certificates, they benefit indirectly from the guarantee. The Freddie Mac SPC certificates represent a pass-through interest in the corresponding multifamily mortgage pass-through certificates.

Stable to Improved Loss Expectations: Fitch's unenhanced ratings are based on an analysis of the underlying collateral pools and do not give any credit to the Freddie Mac guarantee. Overall pool performance and loss expectations of the underlying collateral has been stable to improving since Fitch's last rating action.

Pool-level losses ranged from 2.0% to 7.0% of the current pool balance, with the highest in FREMF 2018-K78 (7.0%), FREMF 2018-K75 (6.2%) and FREMF 2018-K74 (6.0%). There are 43 loans on the servicer's watch lists (6.4% of the 2018 vintage), and one specially serviced loan (0.4% of pool balance of FREMF 2018-K74). Fitch has identified 60 loans as Fitch Loans of Concern (FLOCs) due to declining occupancy and cash flow, low DSCR and/or sponsor issues. The average FLOC concentration was 10.8% (ranging from 0.5% to 23.5%), with the highest concentrations in FREMF 2018-K78 (23.5%), FREMF 2018-K74 (21.2%) and FREMF 2018-K81 (19.2%).

Increased Credit Enhancement (CE); Increased Defeasance: The upgrades and Positive Outlooks are based on the increased credit enhancement and defeasance since Fitch's last rating action. As of the December 2022 remittance reporting, the pool balances have paid down by an average of 2.2% (ranging from 0.4% to 9.8%) since issuance. Additionally, 121 loans (14.9% of the 2018 vintage) are fully defeased, up from 3.7% of the vintage at the last rating action. Individual pool defeasance ranges from 5.5% to 38.0% of their respective pools.

FREMF 2018-K72: paydown of 2.2% since issuance (up from 1.5% at the last rating action); defeasance of 13.5% of current pool (up from 3.7% at the last rating action);

FREMF 2018-K73: paydown, 1.1% (0.7%); defeasance, 9.7% (0.0%);

FREMF 2018-K74: paydown, 4.5% (0.7%); defeasance, 11.3% (3.3%);

FREMF 2018-K75: paydown, 1.2% (0.7%); defeasance, 12.7% (0.4%);

FREMF 2018-K76: paydown, 0.8% (0.6%); defeasance, 17.7% (8.4%);

FREMF 2018-K77: paydown, 1.0% (0.7%); defeasance, 6.3% (1.9%);

FREMF 2018-K78: paydown, 1.0% (0.6%); defeasance, 5.5% (1.0%);

FREMF 2018-K81: paydown, 1.6% (1.2%); defeasance, 22.8% (8.6%);

FREMF 2018-K82: paydown, 0.6% (0.3%); defeasance, 14.5% (0.7%);

FREMF 2018-K83: paydown, 0.4% (0.2%); defeasance, 13.6% (1.2%);

FREMF 2018-K731: paydown, 9.8% (5.6%); defeasance, 38.0% (12.2%).

Additional Loss Considerations: To test the viability of the Positive Rating Outlooks, Fitch applied a stress scenario that assumed a higher cap rate and stress to the servicer-reported NOI, and considered paydown from the defeased loans.

Senior and Student Housing Exposure: Twenty loans (3.1% of the 2018 vintage) are secured by senior housing properties. Forty-four loans (8.4%) are secured by a student housing property or multifamily property with a high student concentration. Fitch's base case analysis applied higher cap rates to these multifamily sub-classifications as they are considered more volatile and/or may require more operational experience than traditional multifamily assets. These additional stresses supported the current ratings and Outlooks.

RATING SENSITIVITIES

Factors that could, individually or collectively, lead to negative rating action/downgrade:

Downgrades of the unenhanced ratings could occur with an increase in pool level expected losses from underperforming or specially serviced loans. While not expected, downgrades to classes B and C could occur if loss expectations for the pool increase significantly, performance of the FLOCs or properties vulnerable to the coronavirus do not stabilize to pre-pandemic levels and/or loans face difficulty refinancing at maturity.

The unenhanced ratings represent a detachment from the guarantee provided by Freddie Mac for their respective classes. Should the performance of the underlying collateral deteriorate enough to warrant a downgrade to any of the classes benefiting from the Freddie Mac guarantee, only the unenhanced ratings would be downgraded. The long-term ratings for those classes that benefit from a guarantee would be rated at the higher of Freddie Mac or the underlying rating without the guarantee.

Factors that could, individually or collectively, lead to positive rating action/upgrade:

Upgrades of classes B and C could occur if there is continued stable to improved asset performance coupled with additional paydown and/or defeasance. However, adverse selection, increased concentrations or the underperformance of particular loans could cause this trend to reverse.

Best/Worst Case Rating Scenario

International scale credit ratings of Structured Finance transactions have a best-case rating upgrade scenario (defined as the 99th percentile of rating transitions, measured in a positive direction) of seven notches over a three-year rating horizon; and a worst-case rating downgrade scenario (defined as the 99th percentile of rating transitions, measured in a negative direction) of seven notches over three years. The complete span of best- and worst-case scenario credit ratings for all rating categories ranges from 'AAAsf' to 'Dsf'. Best- and worst-case scenario credit ratings are based on historical performance.
