An interest-only mortgage is a home loan that allows borrowers to pay only the interest on the loan for a set period of time — typically 5 to 10 years, though some programs may extend longer.
After the interest-only period ends, the loan converts to a fully amortizing mortgage, and payments increase to include both principal and interest.
Interest-only loans are designed for financially strong borrowers who want short-term payment flexibility and long-term strategic options.
What Is an Interest-Only Mortgage?
An interest-only mortgage has two phases:
Phase 1: Interest-Only Period
-
Monthly payments cover interest only
-
Principal balance does not decrease
-
Payments are significantly lower than a fully amortized loan
Phase 2: Repayment Period
-
Loan converts to principal + interest payments
-
Monthly payments increase
-
Loan begins amortizing over the remaining term
Example:
On a $500,000 loan at 7%:
-
Interest-only payment ≈ $2,917/month
-
Fully amortized payment would be significantly higher
The interest-only structure reduces early cash flow obligations.

Interest-Only Mortgage vs Fixed-Rate Mortgage
| Feature | Interest-Only | Fixed-Rate Mortgage |
|---|---|---|
| Initial Payment | Lower | Higher |
| Principal Reduction | No (during IO period) | Yes |

Risks to Consider
While interest-only loans offer flexibility, borrowers should understand:
-
Payments increase after the interest-only period
-
No equity is built during the IO phase (unless property appreciates)
-
Market conditions may affect refinance options
Proper planning is essential before choosing this structure.

Tax returns (if self-employed)
