Understanding Balloon Loans

What Is a Balloon Loan?

A balloon loan is a short-term loan where payments are calculated on a longer amortization schedule — giving you lower monthly payments — but the entire remaining balance comes due as a lump sum at the end of a shorter balloon term. Think of it as borrowing on a 25-year payment plan but being required to pay off everything owed after 5 or 7 years.

The term "balloon" refers to the large lump sum payment that "balloons" at the end of the loan term — often representing 70–85% of the original loan amount.

Who Uses Balloon Loans?

  • Commercial Real Estate Investors: 5/25 and 7/25 structures are extremely common in commercial real estate. The investor plans to sell or refinance before the balloon comes due, using the lower payments to maximize cash flow.
  • Land Loans: Banks are reluctant to amortize land over 30 years (no depreciating asset to foreclose on). A 5 or 7-year balloon forces a check-in point.
  • Business Equipment Financing: When a business needs lower payments now but expects revenue growth or asset sale before the balloon.
  • Bridge Loans: Short-term acquisition financing while waiting for long-term financing to close. Often 1–3 year balloons.

Typical Balloon Structures

7/30Commercial mortgagesSimilar to residential 30-yr but shorter call
10/20Stable assets, owner-occupied CRELess refinance risk than 5/25
3/15Bridge loans, landShort-term; expect to refinance quickly

The Balloon Risk: What Happens If You Can't Refinance?

This is the central risk of balloon loans. If rates have risen significantly, if your property value has declined, if your business creditworthiness has worsened, or if credit markets have tightened (as in 2008–2009), you may find it impossible or very expensive to refinance when the balloon comes due.

In a worst case, the lender could foreclose if you can't pay the balloon and can't refinance. This is why balloon loans require a concrete exit strategy — not just "I'll refinance later."

Plan for the balloon from day one:

  • • Model refinance scenarios at rates 2–3% higher than today
  • • Ensure the property/asset generates enough income to support refinance at higher rates
  • • Start the refinance process 12–18 months before the balloon is due
  • • Maintain strong credit and clean financials throughout the balloon period

How to Plan for Your Balloon Payment

The most common exit strategies: refinance (get a new loan, hopefully with more equity and a better rate), sell the asset (use sale proceeds to pay off the balloon), or pay it off in cash (rare, but possible if you've been aggressively saving). Some lenders also offer balloon extensions or modifications, though this is at their discretion and may come with fee increases.
