Graduated Payment Mortgages

What Is a Graduated Payment Mortgage?

A graduated payment mortgage (GPM) is a loan that starts with lower payments that increase gradually over time.

It is designed for borrowers expecting rising income.

Initial payments may not fully cover interest, which can lead to negative amortization.

Why It Matters in a Mortgage

GPMs may:

  • Improve short-term affordability
  • Increase long-term cost
  • Require careful income planning

These loans are less common today but may appear in specialized programs.

How It Works

Payments increase on a predetermined schedule.

Early payments may not fully reduce principal.

GPM vs. Standard Amortization

GPM → Rising payments
Standard → Stable payments
