A commercial mortgage that amortises over twenty-five years but matures in seven does not pay itself off. It leaves a balance — the balloon — that comes due in a single payment on a date fixed at closing, and the borrower's job for the entire loan term is to arrange the money that retires it. Most borrowers know this in the abstract. What surprises them is how early the work has to start, and how completely the options narrow once the maturity date is inside ninety days.
There are four ways a balloon gets paid: refinance it, sell the property, extend the existing loan, or pay it from other capital. This guide covers what each one requires, how long each takes, what lenders actually do when a maturity arrives unresolved, and the calendar a borrower should be working backward from.
What is a commercial balloon payment?
A commercial balloon payment is the remaining loan balance that becomes due in full at maturity, because the loan's amortisation schedule is longer than its term. A loan written on a thirty-year amortisation with a ten-year term pays down as though it had thirty years to run, then demands everything still outstanding on the tenth anniversary — typically the large majority of the original principal.
This structure is deliberate on the lender's side. Long amortisation keeps the borrower's monthly payment affordable and the coverage ratio healthy, while the short term lets the lender re-underwrite the credit, reset the rate, or exit the relationship at a date it chooses. The balloon payment is the price of that arrangement, and it is not a flaw in the loan — it is the loan.
How much will the balloon actually be?
The balloon equals the scheduled outstanding balance on the maturity date, which on a typical commercial structure is most of what you borrowed. On a twenty-five or thirty-year amortisation, the early years of every payment are overwhelmingly interest, so a five-, seven-, or ten-year term retires far less principal than borrowers intuitively expect.
Interest-only periods make this sharper. A loan with two or three years of interest-only at the front pays down nothing during that window, so the balloon at maturity is closer still to the original principal. That is a reasonable trade when it buys cash flow during a lease-up or renovation, but it should be entered with the maturity number calculated rather than assumed.
Ask your servicer for the amortisation schedule and read the balance on the maturity line. That single number is the whole planning problem, and it should be in your model from the day the loan closes rather than discovered in year six.
What are your four options when the balloon comes due?
There are four exits — refinance, sale, extension, or payoff from other capital — and they differ mainly in how much lead time each requires. The table below sets them against the two things that decide which is available to you: how long the process takes, and what has to be true about the property or the borrower for it to work at all.
| Option | What it requires | Realistic lead time |
|---|---|---|
| Refinance | Property clears a new lender's coverage and leverage tests at current rates | Start with a year to run |
| Sale | A buyer, a price above the balance plus costs, and a full marketing process | Longer than a refinance |
| Extension | A contractual option with satisfied conditions, or a willing lender | Depends entirely on the loan documents |
| Payoff from other capital | Liquidity you already have, or a capital call your partners will fund | As long as your investors need |
Refinancing is the default path and the one most exposed to conditions outside your control. The property has to clear a new lender's tests at the rate available on the day you apply, not the rate you originally borrowed at. The Federal Reserve Bank of St. Louis records the 10-Year Treasury Constant Maturity Rate at 4.78% on September 4, 2026, and the Secured Overnight Financing Rate at 3.65% on the same date — a borrower whose loan was underwritten against a materially different curve is refinancing into a different world, and the proceeds may not cover the balance.
What do lenders actually do when a maturity arrives unresolved?
A lender facing an unpaid balloon has a spectrum of responses, and where it lands depends far more on the property's performance and the borrower's communication than on the documents. A performing property with a temporary timing problem and a sponsor who called six months early is a very different file from a struggling property whose borrower went quiet.
The common outcomes, roughly in order of preference from the lender's side, are a short extension for a fee, a formal modification that resets terms, a forbearance agreement while a sale or refinance completes, and finally enforcement. Lenders generally prefer any of the first three to the last, because taking a property back converts a performing-ish loan into an owned asset with management obligations and a capital charge.
What moves a file toward the good end of that spectrum is early, documented contact. A borrower who arrives at maturity with a signed term sheet from a refinancing lender and a two-month gap is asking for something specific and temporary. A borrower who arrives with nothing is asking the lender to solve the problem, and the lender's cheapest solution is not necessarily the borrower's preferred one.
What is the right calendar to work backward from?
Work backward from maturity by roughly twelve months for a refinance and longer for a sale, because every step in both processes takes more calendar than a first-time borrower expects. The mistake is treating the maturity date as a deadline for the payoff rather than as the end of a process that has to start much earlier.
A workable sequence looks like this. Twelve months out, pull the amortisation schedule and confirm the exact balloon, then run the property's trailing numbers against current lending terms to see whether a refinance clears. Nine months out, engage lenders and get real quotes rather than indications. Six months out, either have an application in process or have made the decision to sell or extend. Three months out, be executing, not exploring.
Interest-rate timing sits underneath all of it, and the calendar is public. The Federal Reserve's published 2026 schedule puts the remaining Federal Open Market Committee meetings on September 15–16, October 27–28, and December 8–9, with the September meeting carrying a Summary of Economic Projections. A borrower deciding whether to lock a refinance quote or wait can at least schedule that decision around known dates rather than guesswork.
How do you avoid the same problem on the next loan?
Structure the next loan so that its maturity is a choice rather than an emergency, which mostly means paying attention to term length, extension options, and prepayment terms at closing rather than at renewal. Borrowers negotiate hard on rate and then accept the maturity architecture as boilerplate, which is exactly backwards for an asset they intend to hold a long time.
Three provisions are worth real negotiation. Extension options with objective, achievable conditions convert a future crisis into a fee. Prepayment terms that step down rather than lock you in let you refinance early if the market turns favourable. And a term long enough to outlast your business plan means the balloon arrives after the property has stabilised rather than during the work. Borrowers comparing structures should read our guide to bridge financing against permanent debt before choosing a term.
The bottom line
The balloon is not a surprise; it is a date you agreed to at closing, and the only real variable is how much runway you give yourself. Pull the amortisation schedule and know the exact number. Start the refinance conversation about a year out and a sale process earlier still. Call the lender before you have a problem rather than after, because the range of outcomes available to a borrower who is early is much wider than the range available to one who is late.
If your maturity is inside the next eighteen months, see what lenders would quote on the property today — the gap between that number and your balloon is the whole planning problem, and it is better measured now than discovered later.
