TL;DR
CRED iQ reported on September 24 that the special servicing rate on office loans in CMBS (commercial mortgage-backed securities) reached 15.7 percent in August 2026, the highest since at least 2019, across about $189.6 billion of office debt. About 71 percent of distressed office balance reflects failed or imminent refinancing, not missed payments. Over the past year, 51 percent of office loans that moved to special servicing were still current when they transferred, a median of about 11 months before maturity, and most early transfers in a tracked group later went seriously delinquent. Rebuild the debt risk from coverage, rollover, and the refinance path, not from a current flag or headline occupancy.

Special servicing and missed payments are not the same thing, and the difference now sits at the center of the office credit file. On September 24, 2026, CRED iQ's Liam Mulcahy reported that office loans in commercial mortgage-backed securities, or CMBS (bonds backed by commercial mortgages), reached a 15.7 percent special servicing rate in August, the highest since at least 2019. CRE Daily summarized the report on September 27. In CRED iQ's data, office delinquency was 13.2 percent, or 9.8 percent excluding matured loans that are still performing, about 1.6 times the 8.2 percent rate across all property types. Among deals that had reported so far in September, CRED iQ added, office delinquency was running above 14 percent and special servicing above 16 percent.

The data covers about $189.6 billion of office debt across conduit pools, single-asset single-borrower deals, or SASB (one property, one borrower), and CRE CLOs. Conduit office loans ran hotter, at 14.4 percent delinquent and 18.5 percent in special servicing, while SASB sat at 10.7 percent and 11.5 percent. Office special servicing was 14.9 percent a year earlier and 10.6 percent in July 2024. For your memo, the harder question is what special servicing and current actually measure when most of the distress is about refinancing, not bounced checks.

What 15.7 percent special servicing actually means

Special servicing is the workout desk that takes over a CMBS loan when it is in trouble or headed there: a default, a maturity default, an imminent default, or a borrower's request for relief. Delinquency is the payment clock. The two overlap, but they are not the same. CRED iQ's point is that about 71 percent of distressed office balance reflects failed or imminent refinancing rather than missed monthly payments. Much of the book moved to the workout desk because the maturity and the refinance path broke, not because the borrower stopped paying.

That is why a loan can be current and in special servicing at the same time and still leave your investment committee, or IC, with a problem. A transfer while current usually means someone already saw the wall: a weak debt service coverage ratio, or DSCR (net operating income divided by debt service), a lease rollover, or a takeout lender that will not refinance at today's rates and proceeds. Treat special servicing as a workout flag and delinquency as payment status, then underwrite the refinance path either way.

Current at transfer is not a clean bill of health

CRED iQ found that 51 percent of office transfers over the past twelve months were still current when they moved, up from 42 percent the year before, with a median of about eleven months left before maturity. One SoHo Square, backed by roughly $469 million of CMBS, transferred in late August while current, nearly two years before its 2028 maturity.

The follow-through is worse. CRED iQ tracked 93 office loans that transferred while current ahead of maturity between August 2024 and August 2025. By August 2026, 72 percent had gone 60 or more days delinquent or matured without paying off at some point, 43 percent were still in that state, and only 15 percent were back with the master servicer and current. Loans that were already delinquent when they transferred reached serious delinquency 92 percent of the time. Among loans of $100 million or more, 63 percent later defaulted and about a third returned to the master servicer; below $100 million, 74 percent defaulted and only 11 percent came back. Willis Tower and 1211 Avenue of the Americas transferred while current and have since returned, which shows recovery is possible without making current at transfer a clean bill of health.

CRED iQ also notes that 2015 and 2016 ten-year office loans paid off at maturity at only 47 percent and 44 percent by balance, compared with 79 percent and 76 percent for other property types. A maturity does not wait for a 60-day late notice.

Full occupancy does not clear refinance risk

Headline occupancy can mislead the same way a current flag can. Crossroads III in Sunnyvale, a $209 million loan, was 100 percent leased with Apple as the largest tenant. It was extended once, moved to special servicing in August, and received a notice of default on September 1. The $138 million GSK R&D Centre loan in Rockville transferred ahead of its 2027 maturity as its only tenant moved out, even though the property still reports full occupancy. A fully leased line on a servicer report is not a path to takeout.

When the offering memorandum, or OM (the broker's marketing package for a sale) leads with fully leased or still current, ask what net operating income, or NOI (income after operating expenses, before debt service) supports after the next rollover, what DSCR clears at today's debt cost, and whether a refinancing or sale at a believable exit cap rate (the rate the next buyer will use to value the property when you sell) actually pays off the loan. Occupancy is an input, not the refinancing.

Looking ahead, roughly $39 billion of office CMBS matures in the next twelve months. About $13.9 billion of it is not yet distressed but already shows warning signs: DSCR below 1.25x, occupancy down ten or more points since securitization, or a recent watchlist flag. The largest include 3 Bryant Park ($1.13 billion, watchlisted in May) and 280 Park Avenue ($1.08 billion, with debt service coverage of 0.72x).

Rebuild the debt risk from DSCR and maturity

When a file leans on current, not delinquent, or fully leased as proof the debt is fine, put three columns on one page: payment and servicer status; DSCR, lease rollover, and months to maturity; and what a realistic refinancing or sale clears at today's rates and proceeds. Special servicing at 15.7 percent and a 71 percent refinance-driven share of distress already live in the last two columns. Your memo should too.

Rebuild from the T-12 (the trailing twelve months of a property's actual income and expenses), the rent roll, and the debt schedule. Check whether in-place NOI still covers debt service after known vacancies, expense growth, and free rent, and whether a refinancing clears the balance if the largest tenant does not renew on the seller's terms.

AcquiOS helps without pretending to decide whether the next office OM fits your buy box (the screens that decide which deals you pursue). It moves the OM, T-12, rent roll, and exhibits into your team's existing Excel template with source citations, so analysts test DSCR, rollover, and the refinance path instead of retyping pages. AcquiScore can mark Proceed, Caution, or Pass against your written screens once the file is built. It does not decide refinance risk for your IC.

What to do this week

Take one office or office-adjacent OM that leans on current, performing, or headline occupancy as comfort on the debt. Add a one-page check with payment and servicer status, DSCR with lease rollover and months to maturity, and what a realistic refinancing or sale clears after costs.

If the thesis only works when you treat a current flag or full occupancy as proof that a refinancing will clear, say so in the memo and size the bid accordingly.

Frequently Asked Questions

Is special servicing the same as delinquency?

No. Delinquency tracks late payments. Special servicing is the workout process for loans in trouble or headed there, including maturity and refinance stress. CRED iQ reports that about 71 percent of distressed office balance reflects failed or imminent refinancing rather than missed payments, which is why current loans still transfer.

Why did so many current office loans transfer?

CRED iQ found 51 percent of office transfers in the past year were current when they moved, a median of about eleven months before maturity, as servicers and borrowers acted on refinance risk before a payment was missed. In a tracked group of 93 early current transfers, 72 percent later went 60 or more days delinquent or matured without paying off.

Does full occupancy mean the refinancing will clear?

No. Crossroads III in Sunnyvale was 100 percent leased with Apple as the largest tenant and still moved to special servicing, then received a default notice after an extension. The GSK R&D Centre loan in Rockville transferred ahead of maturity as its only tenant left, while the property still reported full occupancy. Rebuild from DSCR, rollover, and takeout, not the occupancy line.

How does AcquiOS help when a file leans on current or full occupancy?

AcquiOS moves the OM, T-12, rent roll, and exhibits into your team's existing Excel template with citations, so your team can test DSCR, lease rollover, and the refinance path without treating a current flag or a fully leased line as proof that maturity risk is cleared. It supports judgment. It does not replace it.
