Graduated Payment Mortgages

A graduated payment mortgage is a home loan that starts with lower monthly payments, which gradually increase over a set period—typically 5 or 10 years. After that period, the payments become fixed for the remaining life of the loan.

This type of mortgage may help some borrowers qualify for a home loan by offering a lower initial payment, especially when interest rates are higher.

However, lower payments in the early years may not fully cover the interest charged on the loan. When this happens, the unpaid interest can be added to the loan balance, increasing the amount you owe over time. This is known as negative amortization.

Understanding how your payments may change and how they can affect your loan balance is important when deciding whether a graduated payment mortgage fits your financial goals.

Understanding Negative Amortization

Some graduated payment mortgages may involve negative amortization. Negative amortization happens when the monthly payment is not enough to cover all the interest due. When that happens, the unpaid interest may be added to the loan balance.

The CFPB explains that negative amortization means the amount owed can increase even when payments are made, because the payment is not enough to cover the interest.

Things to Consider

Graduated payment mortgages are less common than standard fixed-rate or adjustable-rate loans, and availability may vary by lender and program. Before considering this type of loan, borrowers should understand:

The scheduled payment increases
The highest expected payment
Whether the loan balance could increase
How long the lower-payment period lasts
The total cost over time
Whether future income is realistic and reliable

Who May Consider This Option?

A graduated payment mortgage may be considered by borrowers who expect income growth and want to understand lower initial payment structures. However, it should be reviewed carefully because future payment increases can affect long-term affordability.
