Enter Loan Details
Principal, rate, and amortization term determine the monthly payment. A 30-year amortization at 7% on $180K = $1,197/mo P&I.
2
Set the Balloon Date
The balloon date is when the remaining balance is due in full. In seller finance and creative deals, 3-7 years is typical. At that point, the buyer refinances conventionally.
3
Add Extra Payments
Extra monthly payments reduce the balloon balance. Even $200/mo extra on a 5-year balloon saves ~$12K in the amount owed at balloon.
4
See the Balloon Balance
Most early-year balloon payments are very close to the original principal because early amortization is mostly interest. Year 5 of a 30-yr loan: only ~5% of principal paid down.
5
Check the Refi Payment
At balloon, the buyer must refinance the remaining balance. The calculator shows the new payment assuming current rates at balloon date.

Compare Balloon Dates
The pro forma shows how much lower the balance (and refi payment) is with a 2-year extension. Negotiating a longer balloon can significantly improve buyer qualification odds.
A balloon payment is a lump-sum payment of the remaining loan balance due at the end of a specified period (the balloon date). Balloon mortgages are common in seller financing, hard money loans, and commercial lending.
The key insight: because loans amortize over 30 years, very little principal is paid down in the early years. A 5-year balloon on a 30-year amortization schedule still has 95%+ of the original balance remaining. The buyer's plan for paying off the balloon must be realistic -- typically a conventional refinance.
Balloon risks for buyers: if the property hasn't appreciated enough or credit hasn't improved, the buyer may not qualify for a refinance and could lose the property. Structure balloon terms with a realistic exit strategy.
