A balloon payment is the outstanding principal balance that comes due in a lump sum at maturity because the payment schedule was built to retire the loan over a longer period than the loan’s term. The balloon equals the original principal less the principal repaid through scheduled amortization, and the borrower repays it by refinancing or selling.
Why do CRE loans balloon?
Commercial real estate loans balloon because the amortization schedule and the loan term are set independently. The schedule sizes the monthly payment as if the loan will be repaid over a long period; the term ends the loan well before that period runs out. At the maturity date the schedule is unfinished, and the unfinished portion is the balloon.
Lenders accept the structure because the property, not the payment schedule, is the source of repayment. A stabilized property is expected to support a new loan at maturity, and the balloon is retired with the proceeds of that new loan or with sale proceeds. Borrowers accept it because a long schedule lowers debt service, which raises coverage and cash flow during the term.
Fully amortizing loans, where the term and the schedule end on the same date, exist in CRE but are the exception. Most permanent, CMBS and agency loans balloon, and every bridge loan and construction loan balloons at the full amount.
How is the balloon payment calculated?
Balloon payment = original principal minus cumulative scheduled principal paid through the maturity date.
Each monthly payment on an amortizing loan is split between interest and principal. Early payments are mostly interest, so principal reduction is slow at first and accelerates late in the schedule. A loan that matures early in its schedule has repaid a small share of the principal, and the balloon is most of the original balance.
Illustrative example:
| Input | Amortizing loan | Interest-only loan |
|---|---|---|
| Original principal | $10,000,000 | $10,000,000 |
| Fixed rate | 6.00% | 6.00% |
| Amortization schedule | 30 years | None |
| Loan term | 10 years | 10 years |
| Monthly payment | About $59,955 | $50,000 |
| Principal repaid during term | About $1,631,000 | $0 |
| Balloon at maturity | About $8,369,000 | $10,000,000 |
The amortizing loan repays a modest share of the balance over ten years, and the rest comes due as a balloon. The interest-only loan repays nothing, so the balloon is the full original principal.
How do interest-only loans balloon?
An interest-only loan has no scheduled principal payments, so the balloon equals the amount borrowed. A partial interest-only loan amortizes only after the IO period ends, and the balloon is larger than it would be under a schedule that started at closing, because fewer amortizing payments were made before maturity.
How does a borrower repay a balloon?
There are two routes. A refinance replaces the maturing loan with a new one sized on the property’s current net operating income, the prevailing rate and the new lender’s loan-to-value and coverage limits. A sale retires the balloon from the purchase price, and the equity after payoff is the seller’s proceeds.
Both routes depend on conditions at maturity, which is why the balloon is a planning event and not an accounting entry. If the property’s income has fallen or rates have risen since closing, the new loan may be smaller than the balloon, and the borrower funds the gap with equity, a mezzanine loan or preferred equity. Extension options, where the loan documents grant them, buy time but are conditioned on tests the property must pass.
Maturity planning starts well before the date. The prepayment window, the expiry of any rate cap or swap, the lender’s extension notice deadline and the takeout lender’s own closing timeline all sit around the balloon date, and a portfolio with many loans has many of these dates in motion at once. A construction-to-permanent loan is one structure built to remove the first balloon by converting to permanent debt without a second closing.
How balloon payments show up in LoanBoss
LoanBoss models each amortization type, including interest-only periods, partial IO, agency floater re-amortization and fully custom schedules, so the balance projected at maturity follows the loan’s actual schedule inside the cashflows. IO ending dates and extension notices are among the critical dates the platform tracks, and hedge expiries carry live mark-to-market and replacement cap costs.
Frequently Asked Questions
Is a balloon payment the same as the maturity date payoff?
The balloon is the principal portion of the payoff. The full payoff at maturity also includes accrued interest through the payoff date and any fees the loan documents charge at repayment.
Does every commercial real estate loan have a balloon payment?
No. A fully amortizing loan retires the balance with its final scheduled payment. Fully amortizing structures are uncommon in CRE, and most permanent, bridge and construction loans balloon.
How large is the balloon on an interest-only loan?
The full original principal. With no scheduled principal payments, the balance at maturity equals the amount borrowed.
What happens if the borrower cannot pay the balloon?
The loan is in maturity default. The borrower’s options are an extension if the documents allow one, a modification or forbearance negotiated with the lender, a sale, or new capital to close the gap.
Does a shorter amortization schedule reduce the balloon?
Yes. A shorter schedule directs more of each payment to principal, so more of the balance is repaid before maturity and the balloon is smaller. The trade is higher debt service during the term.
