On a Tuesday in May 2026, Trepp released its 2025 CMBS Reappraisal Report. The headline: $23 billion of collateral reappraised at a median 53% discount to origination. Office alone accounted for more than half the balance.
Reappraisals are not a market-wide signal. They are a distress tape. A servicer only orders a new appraisal after credit deterioration has become impossible to ignore—maturity default, delinquency, special servicing transfer, or workout trigger. The 2025 cohort is a filtered sample of the worst credits in the CMBS universe.
That filter makes the data more useful, not less. It shows where valuation impairment has become structural rather than cyclical. And it reveals which vintages and property types will define workout economics over the next 18 to 24 months.
The 2017–2018 office vintage is the most impaired cohort in the dataset. Median declines of 71% and 67% respectively. These loans were underwritten at peak-cycle leverage and cap rates, then hit by post-COVID demand destruction. The math is brutal: a loan originated at 65% LTV on a property now worth one-third of its original value has no equity cushion and negative debt service coverage.
Urban office reappraised at a median 64% discount. Suburban office: 52%. The gap is 12 percentage points. That spread confirms the office problem is increasingly a concentrated urban central business district problem, not a uniform sector-wide one. Commuter-dependent towers in gateway cities are impaired at a rate that suburban flex and low-rise assets are not.
At valuation declines above 60%, workout math changes materially. Extensions become uneconomic. The borrower has no equity to contribute, and the lender faces a negative carry trade that only worsens with time. Resolutions shift toward note sales, discounted payoffs, and Real Estate Owned (REO) dispositions. The 2025 cohort includes a meaningful number of loans in that territory.
Enclosed malls are the other deep distress category. The cohort shows median reappraisal declines in line with urban office. The structural headwind is the same: a property type that depended on foot traffic and anchor tenants now faces permanent demand compression. Retail reappraisals in 2025 were not a surprise, but the depth of the discount confirms that many mall loans originated between 2014 and 2019 will not refinance at any price.
The 2026 pipeline will be larger. Loans originated in 2018 and 2019 are approaching maturity with no refinancing path at current values. Trepp data suggests the next wave of reappraisals will include a higher share of suburban office and multifamily, where rent growth has stalled and operating expenses have risen. The 2025 cohort is a preview, not the peak.
For institutional investors, the reappraisal data provides a pricing floor. Note buyers can model recovery rates based on actual servicer valuations, not broker opinions. The 53% median discount implies that distressed CMBS bonds backed by office and retail collateral are trading at prices that assume recovery in the 40–50 cent range. That may be optimistic for urban office loans from 2017–2018.
For lenders, the implication is clear: the extension-and-pretend era is over. Servicers are ordering reappraisals and taking impairment. Special servicers are moving toward disposition. The 2025 cohort shows that the market has accepted a new valuation baseline. The question is whether that baseline holds or erodes further as 2026 reappraisals come in.
The 2017–2018 office vintage will define workout economics over the next two years. Median declines of 71% and 67% mean that most of those loans will not be refinanced. They will be resolved through note sales, discounted payoffs, or REO. The recovery rate for those bonds will depend on how quickly the market clears and at what price.
The 2025 reappraisal cohort is a distress tape, not a market forecast. But it is the best data we have on where the bottom might be. For urban office and enclosed malls, the bottom is lower than most models assumed. For the 2017–2018 vintage, the bottom may not have been reached yet.
