Understanding Balloon Payments

A balloon payment is a large lump sum due at the end of a loan term. In interest-only loans, the balloon is typically the entire original loan amount, since no principal was repaid during the interest-only period.

Example: $300,000 IO Loan with Balloon

Loan: $300,000 at 7% for 5 years (IO)

Monthly payment: $1,750 (interest only)

Total interest paid: $105,000

Balloon due at month 60: $300,000

Common Balloon Loan Strategies

  • Refinance before maturity: Most borrowers refinance into a new loan before the balloon comes due
  • Sell the property: Investors often plan to sell before the balloon date
  • Pay off with savings: Some borrowers accumulate funds to pay the balloon in cash
  • Negotiate extension: Some lenders allow a modification or extension at maturity

⚠️ Balloon Risk

If you can't refinance, sell, or pay the balloon at maturity, you could face default. Always have an exit strategy before taking a balloon loan.
