Interest-Only Mortgage

What Is an Interest-Only Mortgage?

An interest-only mortgage allows borrowers to pay only interest for a set period before principal payments begin.

After the interest-only period ends, payments increase to cover both principal and interest.

Why It Matters in a Mortgage

Interest-only loans:

  • Lower initial monthly payments
  • Increase payment risk later
  • Delay equity building

They may appeal to borrowers expecting future income growth or short-term ownership.

However, once principal payments begin, monthly obligations can rise significantly.

How It Works

Loan term: 30 years
First 5–10 years: Interest-only payments
Remaining years: Fully amortized payments

Total interest paid over time is often higher.

Interest-Only vs. Fully Amortized Mortgage

Interest-Only → Delayed principal repayment
Fully Amortized → Principal reduced from first payment

Equity accumulation differs. Lower payments today may mean higher payments tomorrow.
