The basic structure: smaller payments now, large payment later
A balloon payment mortgage lets you pay less each month than you would on a standard 30-year loan, because you agree to pay a large lump sum—the "balloon"—at the end of the loan term. That final payment is typically much larger than your monthly payments, sometimes tens of thousands of dollars.
Here's how the math works: the lender calculates your monthly payment based on a shorter amortization period than the actual loan term. For example, you might have a 7-year balloon mortgage where your monthly payments are calculated as if you were paying off the loan over 30 years, but the entire remaining balance comes due after 7 years. Those lower monthly payments make the loan cheaper to carry month-to-month, but they also mean you're building equity slowly and owe a large amount at the end.
The interest rate on a balloon mortgage is often lower than a traditional fixed-rate mortgage, which is part of why lenders offer them and why borrowers are attracted to them. But that lower rate comes with the trade-off of that final balloon payment hanging over your head.
Key Takeaways
- Your monthly payment is calculated based on a longer payoff period than your actual loan term, so you pay less each month but owe a large balance at the end.
- When the balloon payment comes due, you must either pay the full amount in cash, refinance the remaining balance into a new loan, or sell the property.
- If you cannot refinance or pay the balloon when it's due, you risk defaulting on the loan and losing the property to foreclosure.
- Balloon mortgages work best for borrowers who plan to sell the property or refinance before the balloon comes due, not for those who want to stay long-term.
- Interest rates on balloon mortgages are typically lower than fixed-rate mortgages, but the final payment risk offsets that savings for many borrowers.
What happens when the balloon payment comes due
When your loan term ends—say, after 7 years—the entire remaining balance becomes due when ready. At that point, you have three realistic options: pay it in full from savings or other funds, refinance the remaining balance into a new mortgage, or sell the property and use the proceeds to pay off the loan.
Most borrowers who take balloon mortgages plan to refinance. You would work with a lender to take out a new loan for the balloon amount, converting it into a traditional amortizing loan. However, refinancing is not may provide. Your credit score, income, and the property's current value all affect whether a lender will refinance you. If property values have fallen or your financial situation has weakened, refinancing may be difficult or expensive.
If you cannot refinance and do not have the cash to pay the balloon, you must sell the property. If the sale price is higher than what you owe, you keep the difference. If the sale price is lower than the balloon amount, you still owe the shortfall—the lender can pursue you for that debt even after the sale closes.
The risk if you cannot pay or refinance
The biggest danger of a balloon mortgage is being unable to pay the balloon or refinance when it comes due. If you miss the payment, the loan goes into default. The lender can then begin foreclosure proceedings, which means you lose the home and damage your credit severely.
This risk is not theoretical. Borrowers who took balloon mortgages during the 2000s housing boom often found themselves unable to refinance when the balloon came due in 2007 and 2008, because property values had fallen and credit markets had tightened. Many lost their homes.
Some balloon mortgages include a clause that allows you to extend the balloon payment for a set period—usually a few years—if you cannot refinance. This gives you breathing room, but it is not automatic. You must ask the lender about this option before you sign, and you should get it in writing.
Who balloon mortgages make sense for
Balloon mortgages work best for borrowers in specific situations. If you plan to sell the property within the balloon term—for example, you're buying a home you know you'll leave in 5 years for a job transfer—a balloon mortgage can save you money on interest and monthly payments. The lower monthly cost helps your cash flow while you own it, and you pay off the loan when you sell.
Balloon mortgages can also work for investors who buy properties to renovate and resell quickly. The lower monthly payment reduces carrying costs while the property is being improved, and the sale proceeds pay off the balloon.
Balloon mortgages do not work well for borrowers who want to stay in the home long-term or who are uncertain about their financial situation in 5 to 10 years. The uncertainty about whether you can refinance, combined with the risk of foreclosure if you cannot, makes them risky for people who need stability.
How balloon mortgages compare to fixed-rate and adjustable-rate loans
A standard 30-year fixed-rate mortgage has the same payment every month for 30 years, and you own the home free and clear at the end. You build equity steadily, and there's no surprise payment looming. The trade-off is a higher monthly payment and higher total interest paid over the life of the loan.
An adjustable-rate mortgage (ARM) has a lower initial rate that increases after a set period, usually 3, 5, 7, or 10 years. Your payment rises when the rate adjusts, but you're still paying off the loan gradually. You're not facing a single large balloon payment; instead, your monthly payment increases.
A balloon mortgage has the lowest monthly payment of the three, but it shifts the burden to the end of the loan term. You're betting that you'll either sell the property, refinance successfully, or have the cash to pay the balloon when it comes due. If any of those things don't happen, you're in trouble.
Questions to ask before signing a balloon mortgage
Before you commit to a balloon mortgage, get clear answers to these questions in writing:
- What is the exact balloon amount, and when is it due?
- Can the balloon payment be extended if you cannot refinance, and for how long?
- What is the interest rate, and is it fixed or adjustable during the loan term?
- Are there prepayment penalties if you pay off the loan early?
- What happens if property values fall and you owe more than the home is worth when the balloon comes due?
Do not rely on the assumption that you will be able to refinance. Ask the lender what their refinancing standards are, and whether they will refinance balloon mortgages at all. Some lenders do not offer refinancing to their own balloon borrowers, which means you would have to shop for a new lender when the balloon comes due—and that lender might have stricter requirements.
Frequently Asked Questions
Can I pay off a balloon mortgage early without a penalty?
Some balloon mortgages allow early payoff without penalty, but others charge a prepayment penalty if you pay off the loan before the balloon comes due. This penalty can be substantial—sometimes 3 to 5 percent of the loan amount. Always ask about prepayment penalties before you sign, and get the answer in writing.
What if I want to stay in the home after the balloon comes due?
You would need to refinance the balloon amount into a new loan. This is possible if your credit and income are still good and the property has held its value, but it's not may provide. If you think you might want to stay long-term, a balloon mortgage is risky because refinancing is not certain.
Do balloon mortgages have lower interest rates than fixed-rate mortgages?
Usually yes—balloon mortgages typically carry interest rates 0.5 to 1 percent lower than 30-year fixed-rate mortgages. However, the lower rate is offset by the risk and uncertainty of the balloon payment, so the total cost is not always lower.
What happens if the home is worth less than the balloon payment when it comes due?
If you sell and the sale price is less than what you owe, you still owe the difference. The lender can pursue you for that debt through a deficiency judgment. If you cannot refinance because the home is underwater, you may face foreclosure.
Are balloon mortgages still common?
Balloon mortgages are less common now than they were before 2008, but they still exist. They're most common in commercial real estate and among investors. Consumer balloon mortgages are available but less popular because of the risks they carry.
