What it means
The mechanics are simple once you separate two ideas: the amortisation period used to calculate payments, and the actual term of the loan. A lender might size payments on a 30-year schedule but only commit funds for seven years, which is why so little principal has been repaid when the term expires.
The appeal for a borrower is cash flow. Lower monthly payments free up money for renovations, business expansion or simply surviving the early years of an investment property before rents have caught up with costs.
The appeal for the lender is that it limits how long it is exposed to one borrower and one interest rate. At the balloon date the lender can walk away, reprice the loan, or ask for a fresh valuation and tighter terms.
The risk sits almost entirely with the borrower. If property values have fallen or the borrower's income has weakened, refinancing may not be possible at the balloon date, and the choice becomes a forced sale or a default.
There are common variations worth knowing about. Some balloon mortgages include a conversion option that lets the borrower switch to a fully amortising loan at the balloon date, and others allow an extension if the borrower has met every payment on time and the property still meets the lender's loan-to-value test.
In practice
Real-world examples.
Example
An investor buys a small apartment block with a five-year balloon mortgage, planning to raise rents and refurbish the units. She sells the building in year four at a higher valuation, settling the balloon from the sale proceeds and pocketing the difference.
Example
A dentist buys a practice premises using a balloon structure because the monthly saving of around $900 lets him hire a second hygienist immediately. He refinances into a fully amortising loan at the balloon date once the practice income has grown.
Example
A couple take a seven-year balloon mortgage expecting to move well before it matures. A slower housing market means they are still there at year seven, and they have to accept a refinancing rate two percentage points higher than their original deal.
Formula
Calculation
Monthly payment is calculated on the long amortisation schedule, and the balloon payment is the loan balance remaining at the end of the shorter term.
A landlord borrows $300,000 at a fixed 6% annual interest rate. Payments are calculated on a 30-year amortisation schedule, but the loan matures after 7 years.
Using the standard mortgage payment formula on $300,000 at 0.5% a month for 360 months, the monthly payment is $1,798.65.
Total paid over 7 years (84 payments) = 84 x $1,798.65 = $151,087
Of that total, only a small portion has gone to principal, because early payments on a 30-year schedule are dominated by interest.
Principal repaid over 7 years = $31,082
Interest paid over 7 years = $151,087 - $31,082 = $120,005
Balloon payment due at the end of year 7 = $300,000 - $31,082 = $268,918
So after seven years and more than $151,000 in payments, the landlord still owes $268,918 in one lump. That figure is roughly 150 times the monthly payment, which is the number any borrower should look at before signing.Case study
Seen in the real world.
Ridgeway Property Partners is an invented small landlord business used here as an illustrative example. It financed four terraced rentals with balloon mortgages, all arranged in the same quarter and all maturing in the same year, because the rates on offer at the time were attractive.
When the balloon year arrived, values in that particular town had drifted down about 8% and lenders had tightened their loan-to-value limits, so the partners could refinance only three of the four properties. They sold the fourth at a modest loss to settle its balloon, which cost them roughly two years of the rental profit the portfolio had generated.
The illustrative lesson is about concentration as much as about balloons. Staggering the maturities across four different years would have exposed only one property to any single moment in the market.
Watch out
Common mistakes.
- Reading the low monthly payment as evidence the loan is cheap, when total interest over the term is high precisely because so little principal is repaid.
- Assuming the property will definitely be worth more at the balloon date, which removes the safety margin if values stall or fall.
- Arranging several balloon mortgages that mature in the same year, concentrating refinancing risk into one moment.
Questions
People also ask.
How is a balloon mortgage different from an interest-only mortgage?
An interest-only loan repays no principal at all during the term, while a balloon mortgage repays a little through payments sized on a longer amortisation schedule.
What happens if I cannot refinance at the balloon date?
The lender can demand repayment and ultimately repossess, so most borrowers negotiate an extension, sell the property, or line up alternative finance well in advance.
Are balloon mortgages common for ordinary home buyers?
They are far more usual in commercial and investment property lending, and many residential markets restrict them because of the repayment risk they place on the borrower.
