The short answer: A performing matured balloon is a CMBS loan that reached its maturity date without being paid off while the borrower keeps paying interest. Trepp's headline CMBS delinquency rate leaves these loans out, but under the loan documents the loan is past maturity, and the servicer, not the borrower, controls the timeline from here. Treat the status as a short runway to a refinance or a sale, not a resting place. For context, Trepp's headline delinquency rate rose 17 basis points to 8.02% in September 2026, its highest level since November 2020 (Trepp, October 2, 2026), and that figure counts only the matured balloons that have stopped paying interest.
Performing vs non-performing matured balloon: what's the difference?
The difference is whether the borrower is still paying interest after missing the balloon: a performing matured balloon has failed to repay the balance at maturity but stays current on interest, while a non-performing matured balloon has failed to repay the balance and is not current on interest, which puts it in Trepp's headline delinquency count.
Trepp's guide to its delinquency report (June 29, 2023) defines the two statuses exactly that way, and explains why they exist. Almost all CMBS loans are balloon loans, meaning a lump sum is due on the final maturity date. Some CMBS loans have no amortization at all, so the balloon payment is the full original loan amount. Others amortize; Trepp's example is a 10-year loan amortized for the first 119 months on a 30-year schedule. Either way, the borrower has to refinance, sell or otherwise raise the remaining balance on one date.
When that date passes without a payoff, the loan has not paid off at its balloon date, and Trepp says it can be classified in one of two ways depending on whether the borrower keeps paying interest. That is the whole distinction. "Performing" describes the interest payments, not the loan.
The maturity calendar explains why more owners are asking about it. The Mortgage Bankers Association's 2025 survey of loan maturity volumes, released February 9, 2026, puts the scale in front of every borrower with a 2026 maturity:
Commercial mortgages scheduled to mature in 2026 (MBA, February 9, 2026): $875 billion, 17% of $5.0 trillion outstanding CMBS, CLO and other ABS balances maturing in 2026 (MBA, February 9, 2026): $200 billion, 25% of that group's outstanding balance Change from 2025 (MBA, February 9, 2026): a 9% decrease from the $957 billion scheduled to mature in 2025
MBA notes the dollar figures are unpaid balances as of December 31, 2025, and that balances at maturity will generally be lower because most loans pay down principal.
Does a matured balloon count as delinquent?
A matured balloon counts in Trepp's headline delinquency rate only when the borrower has stopped paying interest; a loan that missed its balloon but stays current on interest is excluded from the headline number, although Trepp reports the share that is past maturity and current on interest in its write-up and still counts maturity default as a special servicing trigger.
Trepp says its headline rate includes six statuses, in ascending severity: 30 days delinquent, 60 days delinquent, 90 days delinquent, non-performing matured balloon, foreclosure and REO. The rate is the delinquent balance divided by the total balance of loans outstanding, and the denominator includes defeased loans.
| Trepp status | In Trepp's headline delinquency rate? | What it means for the borrower |
|---|---|---|
| Trepp status 30 days delinquent | In Trepp's headline delinquency rate? Yes | What it means for the borrower The borrower missed the 30-day grace period after the payment was due |
| Trepp status 60 days delinquent | In Trepp's headline delinquency rate? Yes | What it means for the borrower Between 60 and 89 days past due; Trepp says most CMBS loans transfer to the special servicer at 60 days |
| Trepp status 90 days delinquent | In Trepp's headline delinquency rate? Yes | What it means for the borrower More than 90 days past due; resolution runs through the special servicer |
| Trepp status Performing matured balloon | In Trepp's headline delinquency rate? No | What it means for the borrower Balloon missed, interest current; past maturity, on the servicer's timeline |
| Trepp status Non-performing matured balloon | In Trepp's headline delinquency rate? Yes | What it means for the borrower Balloon missed and interest no longer current |
| Trepp status Foreclosure | In Trepp's headline delinquency rate? Yes | What it means for the borrower The lender or servicer is taking possession of the property |
| Trepp status REO | In Trepp's headline delinquency rate? Yes | What it means for the borrower Foreclosure is complete and the lender becomes the owner of the property |
Here is the September reading, with its definition attached: the share of CMBS balance in those six statuses.
CMBS delinquency rate, September 2026 (Trepp, October 2, 2026): 8.02%, up 17 basis points, highest since November 2020 Office (Trepp, September 2026): 12.16%, up 16 basis points Multifamily (Trepp, September 2026): 8.04%, up 35 basis points Lodging (Trepp, September 2026): 6.18%, up 34 basis points Retail (Trepp, September 2026): 6.58%, down 62 basis points on mall cures Industrial (Trepp, September 2026): 1.14%, unchanged
The headline does not show how many loans sit in performing matured balloon status this month. Trepp says it reveals the percentage past maturity and current on interest in its write-up; the September 2026 figure sits in the full report rather than the public excerpt, so it is not quoted here.
Excluded from the headline does not mean safe. Trepp lists maturity defaults among the reasons a loan enters special servicing, alongside payment defaults, imminent defaults and borrower requests for modifications, and its September 2026 special servicing report says the largest new transfer moved for imminent balloon or maturity default. A loan can be in special servicing without being delinquent.
What happens to a CMBS loan after it becomes a performing matured balloon?
After a CMBS loan becomes a performing matured balloon, it can be transferred to the special servicer, which may extend or modify the loan, grant forbearance, negotiate a payoff or sale, or move toward foreclosure, and because the loan is past maturity, the servicer rather than the borrower decides how long the interest-only runway lasts.
Trepp's Special Servicing 101 guide lists the tools: loan modification, including extending the maturity date, reducing the interest rate or altering the payment schedule; forbearance agreements that temporarily delay or reduce payments; property sale; foreclosure; receivership; deed-in-lieu; and discounted payoff. Trepp describes the special servicer's job as bringing the loan to resolution to maximize recovery for investors, which is the lens your request will be judged through.
Three practical consequences follow.
Get the terms in writing. Continuing to pay interest is not the same as having an agreed extension. Ask the servicer whether it will document a forbearance or extension, with milestones such as a refinance commitment date and a closing date.
Know what is accruing. Default interest, late charges and fees are set by your loan documents and vary from loan to loan, so read the note and ask the servicer for an itemized payoff statement. Have counsel review what the documents allow the servicer to charge and do.
Expect a trial period if the loan is modified. Trepp says a delinquent loan that is modified and becomes current again stays with the special servicer for a modification trial period, typically three months, before it returns to the master servicer.
What will your next lender ask about it?
Your next lender will ask why the loan matured unpaid, what the servicer has agreed to in writing, what the payoff will be on the closing date including any default interest and fees, and whether the property's current cash flow and value support a new loan at today's rates, because those answers set the loan size and the deadline.
The maturity default itself is a fact the new lender will want explained and documented. A record of interest paid on time after maturity is worth showing, because it tells the lender the property still carries its interest. Expect these requests:
- The servicer's payoff statement, with per diem interest and any default interest, late charges and fees itemized
- Any forbearance, extension or modification agreement, and the milestones in it
- Payment history since maturity, showing interest kept current
- The trailing 12-month operating statement, current rent roll and lease rollover schedule
- A current appraisal or broker opinion of value
- Sources and uses: new loan, payoff, closing costs, reserves and any new equity
- A one-page explanation of why the loan did not refinance at maturity
The new loan is sized on today's numbers. A rate and term refinance lender tests coverage and leverage on current income and current rates. If the proceeds fall short of the payoff, the gap has to come from new equity, preferred equity or a bridge loan that buys time to lift income, or from a negotiated payoff with the servicer.
How do you get a refinance placed before the servicer's runway ends?
You get a refinance placed before the servicer's runway ends by packaging the payoff statement, the servicer's written terms, the operating history and a current valuation once, then sending the same file to every lender with a firm closing date; the first option to weigh is a commercial mortgage brokerage that runs the search and the negotiation together.
Option 1, our pick as the publisher of this guide: an AI-native commercial mortgage brokerage. YieldStack is an AI-native commercial mortgage brokerage that arranges financing for commercial real estate investors. Our reasons for listing it first: software matches the deal against 20,000+ loan programs and compares the options, and human brokers structure the refinance, negotiate on the borrower's side and carry the deal toward closing on the servicer's timeline. YieldStack reports a median first offer in under an hour, from an institutional lender. It costs Zero upfront to submit a deal and review offers; YieldStack's broker fee is 0.50–1.00% of the loan amount and is paid only at closing. Every credit decision is made by the lender; YieldStack arranges the introductions and negotiates on the borrower's side, and no loan, rate, or closing is guaranteed.
Option 2: go direct to a bank or life company you already know. This works when the relationship is strong and the property fits its box, and when you can run the negotiation with the servicer at the same time.
Option 3: sell the property. Trepp lists a property sale among the servicer's tools. If the refinance math does not work, a sale that clears the payoff may keep the resolution on your terms; confirm the payoff figure with the servicer before you list.
When the file is ready, send the refinance for review.
The bottom line
A performing matured balloon means you missed the balloon but kept paying interest. Trepp's headline delinquency rate excludes it, yet the loan is past maturity and the servicer controls the clock. Use the time you are given: get the servicer's terms in writing, build the refinance file and run the lender search now, before the runway ends.
