Private-label CMBS structures have emerged as the principal source of delinquency within securitized multifamily financing, according to recent analysis from Trepp. As of August 2026, Trepp tracked a $635.82 billion universe of securitized multifamily loans, of which $11.6 billion was categorized as delinquent. Despite representing only a small portion of that overall market, private-label CMBS accounts for roughly half of the delinquent balance.
Trepp analyst Stephen Buschborn reported that private-label CMBS deals hold $75.48 billion of multifamily debt, equal to about 12% of the securitized multifamily pool. However, these transactions carry a 7.69% delinquency rate, translating to $5.8 billion of delinquent loans. That figure represents 50.2% of all delinquent securitized multifamily debt, indicating that distress is disproportionately concentrated in the private-label CMBS segment.
By contrast, Freddie Mac dominates the securitized multifamily landscape by outstanding balance but shows a markedly lower level of loan trouble. Freddie Mac was cited as holding $518.99 billion of multifamily debt, or roughly 82% of the total securitized universe that Trepp tracks. Its delinquency rate stands at 0.80%, which still equates to a sizable $4.2 billion of delinquent loans. Even at that lower rate, Freddie Mac-backed loans represent 35.9% of the aggregate delinquent multifamily balance.
Commercial real estate collateralized loan obligations (CRE CLOs) comprise a smaller but still meaningful share of securitized multifamily credit exposure. Buschborn noted that CRE CLOs, which primarily consist of floating-rate transitional loans, hold $41.3 billion of multifamily debt. Within this segment, the delinquency rate is 3.88%, corresponding to $1.6 billion of delinquent loans and 13.9% of total delinquent securitized multifamily debt.
Buschborn wrote that the composition of delinquent multifamily loans has shifted significantly over the past two years. At that earlier point, CRE CLOs accounted for the largest share of delinquent securitized multifamily loans, with about 40% of the total. Freddie Mac held approximately 32% of delinquent loans, while private-label CMBS represented the smallest share at 27%. That ranking has since inverted, with private-label CMBS now representing the largest slice of the delinquency pie.
One factor potentially influencing this trend is how CRE CLO managers actively manage their pools. Buschborn noted that managers may remove defaulted or otherwise credit-impaired loans from CLO transactions over time. As a result, the currently reported $1.6 billion of delinquent loans within the $41.3 billion CRE CLO universe may understate the real level of distress among loans that have migrated through those structures. This dynamic, combined with the higher delinquency levels observed in private-label CMBS, underscores how different securitization channels are absorbing credit stress within the multifamily sector.
