What Is a Balloon Mortgage?
A balloon mortgage is a financing arrangement in which the borrower makes relatively small periodic payments for a set initial period, followed by a single large lump-sum payment — the “balloon” — that covers the remaining principal balance. Unlike a standard fixed-rate or adjustable-rate mortgage, the scheduled payments during the loan term do not fully amortize the debt. The borrower must either pay off the balloon amount in cash, refinance into a new loan, or sell the property before the balloon date arrives.
Typical Balloon Mortgage Structures
Balloon mortgages are most commonly structured as 5/25 or 7/23 loans. In a 5/25 balloon, the borrower makes payments for five years based on a 30-year amortization schedule, with the entire remaining balance due at the end of year five. A 7/23 balloon operates identically but extends the initial payment period to seven years. Some balloon products use interest-only payment structures during the initial term, which results in an even larger lump sum at maturity since no principal reduction occurs. Commercial balloon loans may feature terms of 3, 5, 10, or 15 years with amortization periods of 20 to 30 years.
How Balloon Payments Are Calculated
In the most common configuration, monthly payments are calculated as though the loan will be repaid over 30 years using a standard amortization formula. However, the loan matures well before the 30-year mark. At maturity, the borrower owes whatever principal remains on the original amortization schedule. For example, on a $300,000 balloon mortgage at 6.5% with a 7-year term amortized over 30 years, the monthly payment would be approximately $1,896. After seven years of payments, the remaining principal balance — the balloon payment — would still be roughly $279,000. Borrowers should understand that the vast majority of early mortgage payments go toward interest rather than principal, which is why the balloon amount remains so large relative to the original loan.
Reset, Refinance, and Exit Options
Some balloon mortgage contracts include a conditional reset clause that allows the borrower to convert the remaining balance into a fully amortizing loan at a prevailing market rate, provided certain conditions are met. These conditions typically include being current on all payments, occupying the property as a primary residence, and having no subordinate liens that exceed a specified threshold. Absent a reset clause, borrowers must arrange alternative financing — either through a standard conventional refinance, an FHA loan, or another product — before the balloon date. Selling the property before maturity is also a common exit strategy, particularly for investors and borrowers who purchased with a short holding period in mind.
Risks and Regulatory Considerations
Balloon mortgages carry significant refinancing risk. If property values decline, interest rates rise, or the borrowers creditworthiness deteriorates before the balloon date, securing replacement financing may be difficult or impossible. This dynamic contributed to widespread defaults during the 2007-2009 housing crisis. As a result, the Consumer Financial Protection Bureaus Qualified Mortgage (QM) rule generally excludes balloon-payment features from QM designation, with narrow exceptions for small creditors operating in rural or underserved areas. Loans that fall outside QM standards do not receive the legal safe harbor protections that shield lenders from ability-to-repay litigation. Borrowers considering a balloon mortgage should review this in the context of non-QM loan requirements and evaluate whether the short-term payment savings justify the maturity risk.
Who Uses Balloon Mortgages and Current Market Availability
Balloon mortgages are most commonly used by commercial real estate borrowers, property investors with defined exit timelines, and individuals who expect to relocate or sell within the initial payment period. In the residential market, balloon products have become far less prevalent since the post-crisis regulatory reforms. Most mainstream residential lenders no longer offer balloon mortgages to consumer borrowers. Where they do exist, they are typically portfolio loans held by community banks or credit unions. Commercial balloon loans remain standard in multifamily and commercial lending. Compared to adjustable-rate mortgages (ARMs), which adjust periodically but continue to full term, and interest-only loans, which defer principal but eventually convert to amortizing payments, balloon mortgages present a harder deadline with fewer built-in protections. Borrowers who need lower initial payments but want to avoid balloon risk may find that choosing an ARM or interest-only ARM provides more flexibility.
