What You Need to Know About 10-Year Interest-Only Loans

In a major shift, lenders are now offering interest-only (IO) loans of up to 10 years for owner-occupiers. This is a significant extension from the previous standard of five years, and it’s raising questions across the industry and among homeowners alike. Is this a smart financial tool or a long-term trap?

Let’s explore what a 10-year IO loan really means – and whether it could be a friend or foe to your finances.

What is an Interest-Only Loan?

An interest-only loan allows you to pay only the interest component of your mortgage for a set period (in this case, up to 10 years). During this time, your loan balance doesn’t reduce, but your monthly repayments are significantly lower than a principal and interest (P&I) loan.

After the IO period ends, repayments increase as you begin paying down the loan principal over the remaining term.

AMP Bank’s New Offering

Recently, AMP Bank introduced a 10-year interest-only loan for owner-occupiers, a move that’s sparked interest and debate in equal measure. It’s one of the few lenders willing to stretch the interest-only period to a full decade—giving borrowers extended cash flow flexibility.

But does longer flexibility mean more financial freedom or more risk?

The Pros and Cons of 10-Year IO Loans

Benefits

• Improved Cash Flow: Lower repayments free up funds for other financial goals.
• Offset Account Advantage: With an offset account (e.g., $100,000), you can reduce interest payable while retaining access to your cash.
• Strategic Flexibility: Useful for those with irregular income, in transition periods, or planning to sell before the IO term ends.

Drawbacks

• Higher Long-Term Cost: You’re not paying down the loan, so you’ll pay more interest over time.
• Sudden Repayment Increase: After 10 years, P&I repayments can jump significantly.
• Reduced Equity Growth: Without principal repayments, equity builds solely from property appreciation—not from reducing your debt.
• Stricter Lending Conditions: APRA requires lenders to assess your ability to repay the loan under P&I terms at higher buffer rates, so qualifying isn’t easy.

Recent APRA Statistics

According to APRA (Australian Prudential Regulation Authority), interest-only loans are slowly regaining popularity but still remain tightly regulated due to their higher risk profile. This makes proper planning even more important if you’re considering one.

Case Study: Retirees Using IO for Flexibility

Meet John and Linda

John and Linda, both in their early 60s, recently downsized and purchased a $750,000 apartment. With a $100,000 offset account, they chose a 10-year IO loan to keep their repayments low while maintaining flexibility with their retirement savings.

Outcome

This strategy allows them to:

• Preserve liquidity
• Avoid selling assets for living expenses
• Access tax benefits in a strategic superannuation drawdown

Tips for Using IO Loans Wisely

• Use Sparingly: IO loans shouldn’t be your default mortgage choice—treat them as a tool for specific scenarios.
• Have an Exit Strategy: Whether it’s selling, refinancing, or switching to P&I, know what happens after the IO term.
• Understand Buffer Assessments: Lenders assess IO loans using P&I repayments at higher interest rates, so ensure you qualify under those conditions.

Final Thoughts

Interest-only loans—especially with a 10-year term—can be incredibly useful when used with care. For the right borrower, they offer flexibility and strategic advantages. But they come with higher long-term costs and risk if mismanaged.
