A Balloon Mortgage is a loan where the borrower makes regular payments for a set period but does not fully repay the loan through those payments.
Instead, a large remaining balance becomes due at the end. This final amount is called the balloon payment.
For example, a borrower may make monthly payments as if the loan were being repaid over 30 years, but the actual loan may mature after only 5 or 7 years.
At that point, the borrower must usually:
- Pay the remaining balance in full
- Refinance the loan
- Sell the property and use the proceeds to repay it
Balloon mortgages can offer lower initial monthly payments than a fully amortising loan.
However, they carry significant risk because the borrower may face a very large payment later. If refinancing is unavailable or property prices have fallen, repayment can become difficult.
