A CMBS loan is a commercial mortgage that a lender makes and then transfers into a trust with other loans, where it backs bonds called commercial mortgage-backed securities (CMBS).
For you, that transfer decides who you deal with for the life of the loan, what it costs to leave early, and who controls your rents if the property hits trouble. Trouble is also rising. Trepp's CMBS delinquency rate rose to 8.02% in September 2026, its highest level since late 2020, according to Scotsman Guide's October 6, 2026 report.
Key points
- After closing, a trust holds your loan and servicers run it under the trust's rules. A special servicer steps in if the loan defaults.
- Terms are generally 5, 7 or 10 years with a balloon at maturity, generally non-recourse except for listed "bad boy" acts, and often costly to pay off early.
- It suits a stable property you plan to hold for the full term. Get the exit cost and the cash management triggers in writing before you sign.
What is a CMBS loan?
A CMBS loan is a commercial mortgage made to be securitized. After closing, the lender transfers it to a trust along with many other loans. The trust holds the mortgages and issues bonds backed by them, and investors buy those bonds. A master servicer collects your payments. If the loan defaults, a special servicer takes over.
The law firm Kohrman Jackson & Krantz (KJK) puts it in one line in its overview of CMBS loans: "Numerous loans are pooled and then transferred to a trust, the trust then issues a series of bonds." So your loan belongs to the trust, and your payments flow through it to bondholders you'll never meet.
Who do you deal with after a CMBS loan closes?
The master servicer handles the routine work. KJK lists collecting payments, reporting to investors, advancing funds on delinquent loans, reporting to the trustee, and transferring non-performing loans to the special servicer.
The special servicer handles loans in default. KJK says it can negotiate a workout, such as a loan modification, a negotiated payoff, a sale of the loan or a deed in lieu of foreclosure, or take the property through foreclosure.
KJK notes that CMBS requirements "allow less flexibility in servicing the loan than may otherwise be permitted," and that "it may be very difficult for a borrower to obtain financial assistance from the master servicer." Before you sign, ask which changes need servicer consent while your loan is current, so you know your room to move before you need it.
What terms come with a CMBS loan?
Your loan agreement controls, so treat each row below as a question for your attorney.
| Term | What KJK describes | What to check in your documents |
|---|---|---|
| Length | "Generally offered for a 5, 7 or 10 year term" | Your maturity date, and whether your plan for the property fits inside it |
| Payments | Amortized "generally 25 or 30 years"; some loans qualify for interest-only payments | How large the balloon will be (worked example below) |
| Recourse | "Generally structured as non-recourse," with full recourse for certain "bad boy" acts | Non-recourse means that in a default, the lender's recovery is generally limited to the property. The carve-outs list the acts that would make you personally liable for the debt. |
| Borrower | Single purpose entity requirements | What the borrowing entity may own and do |
| Other debt | Loans "often prohibit secondary or supplemental financing" | Whether a second loan for a renovation is allowed at all |
| Early payoff | Prepayment penalties, defeasance or yield maintenance, where prepayment is permitted | When prepayment is allowed and how the cost is calculated |
| Sale | May be assumable by a buyer for a fee, generally on the same terms | Whether assumption is allowed and what it costs |
| Cash flow | Subject to a cash management process; in a default, the special servicer controls cash flow | What events trigger cash management |
KJK's overview also lists upsides: "competitive, lower interest rates than traditional loans," a "higher loan-to-value ratio," and fees that "are often less than fees incurred with a traditional loan." That overview dates from 2020, so test those points against a current quote.
How big is the balloon on a CMBS loan?
KJK notes that CMBS terms "require the borrower to make a balloon payment at maturity." The size depends on how much principal you pay down along the way.
Hypothetical example: a $10,000,000 CMBS loan with a 10-year term at an illustrative 6% rate. The rate is not a market quote. It's there to show the shape of the trade.
| Payment structure | Monthly payment | Yearly payment | Owed at year 10 |
|---|---|---|---|
| Interest-only for the full term | $50,000 | $600,000 | $10,000,000 |
| 30-year amortization | about $59,955 | about $719,500 | about $8.37 million |
Interest-only lowers your payment by about $119,500 a year, or about $1,195,000 over the full term. But you would owe about $1,631,000 more at year 10, because none of the principal was paid down. The difference between those two figures, about $437,000, is the extra interest you pay for carrying the full $10,000,000 balance for the whole term.
Either way, year 10 needs a refinance or a sale that covers the balance. Our piece on planning for a maturing CMBS loan covers when to start that work.
What does it cost to leave a CMBS loan early?
KJK puts it plainly: "Where prepayment is permitted, achieving the payoff is often complicated and expensive." Depending on the documents, you may face prepayment penalties, defeasance (replacing the property with another form of collateral), or yield maintenance, which KJK ties to "the difference between their current interest rate and U.S. Treasury yields."
If there's a real chance you will sell or refinance before maturity, ask for the exit cost as a dollar estimate at a few points in the term before you sign, and weigh it against what the loan saves you. Our breakdown of what defeasance on a commercial mortgage costs works through that math.
How are CMBS loans performing in 2026?
Trepp and KBRA measure different pools, so read their figures separately. Trepp's delinquency rate was 8.02% in September 2026, up from 7.85% in August. By property type, office was 12.16% and multifamily was 8.04%. Trepp's report said five large single-asset, single-borrower loans drove much of the increase, and four of those went nonperforming or to foreclosure in September after missing maturity payoff dates earlier in the year.
KBRA covers a different set: its $344.4 billion rated universe of U.S. private label CMBS. Its September 2026 report, released September 30, 2026, put the delinquency rate at 7.7% and the distress rate at 10.3%. The distress rate counts delinquent loans plus current loans that are with a special servicer.
These figures describe pools of loans, not your property. They do show that missed balloons and special servicing are live issues, so read the default sections as closely as the rate.
Is a CMBS loan right for your property?
A CMBS loan tends to fit a stable, income-producing property you plan to hold through the full term. It fits poorly if you may sell or refinance early, will need a second loan for capital work, or want a lender you can call to change a term on a performing loan.
Settle three things before you sign:
- The exit cost. Get the prepayment, defeasance or yield maintenance cost in dollars, not just the clause.
- The cash management triggers. Know exactly which events let the servicer take control of your rents.
- The balloon plan. Run the year-10 balance and ask whether the property's income could support a refinance of that amount.

FAQ
Is a CMBS loan recourse or non-recourse?
KJK says CMBS loans are "generally structured as non-recourse loans," with full recourse for certain "bad boy" acts by the borrower. Your personal exposure depends on the exact carve-outs, so have your attorney read them before you sign.
Can a buyer assume a CMBS loan?
It may be possible. KJK says that "upon payment of a fee, the loan may be assumable by a purchaser," and the buyer is generally bound by the same terms as the original owner. Whether yours can be assumed, and on what conditions, depends on your loan documents.
What happens if you default on a CMBS loan?
The loan moves to the special servicer, which KJK says takes control of the property's cash flow during the default. KJK also warns of added costs such as default interest, special servicer fees and legal fees. If a CMBS loan payment or balloon is at risk, contact your servicer early.
