Interest-Only Mortgage Explained

Overview

An interest-only mortgage is a type of home loan where, for a specified period, the borrower only pays the interest that has accrued on the loan balance. This means the principal loan amount remains unchanged during the interest-only term.

Key Concepts

Interest-Only Period

This is the initial phase of the loan, typically lasting 5 to 10 years, during which only interest payments are required. Your monthly payments are lower during this time.

Repayment Period

Following the interest-only period, the loan enters the repayment phase. During this time, your monthly payments will increase significantly as they must cover both the remaining principal and ongoing interest.

Deep Dive

Unlike traditional amortizing loans where each payment gradually reduces the principal, interest-only loans defer principal repayment. This can lead to lower initial cash outflows but requires careful planning for the higher payments later.

Amortization Schedule

At the end of the interest-only term, the loan typically converts to a standard amortizing loan. The remaining balance is then spread over the remaining loan term, resulting in substantially higher monthly payments.

Applications

Interest-only mortgages can be suitable for:

• Borrowers who expect their income to increase significantly in the future.
• Investors who use the property for rental income and want to maximize cash flow initially.
• Individuals who plan to sell the property before the interest-only period ends.

Challenges & Misconceptions

A common misconception is that payments remain low indefinitely. Borrowers must be prepared for the substantial increase in payments after the interest-only term expires. Failure to do so can lead to default.

FAQs

Is an interest-only mortgage right for me?

It depends on your financial situation, future income expectations, and investment strategy. It requires a strong understanding of the repayment phase and the ability to manage larger payments later.

What happens after the interest-only period?

Your loan will begin to amortize. This means your payments will increase to cover both the principal balance and the ongoing interest, calculated over the remaining loan term.
