Interest-only loan

Updated November 2026

A loan where, for a set period, you pay only the interest and none of the principal.

At a glance
  • Lower repayments during the interest-only period
  • The loan balance does not reduce
  • Repayments rise when the period ends

How it works

Interest-only periods usually run up to 5 years for investment loans. After that, the loan reverts to principal and interest unless extended or refinanced.

The trade-off

Lower repayments can help cash flow, but you build no equity through repayments and pay more interest overall.

For investors

Some investors use interest only on investment loans and pay down their home loan instead. Whether that suits you is a question for your broker and accountant.

Common questions

Are interest-only rates higher?

Usually slightly higher than principal and interest rates.

Can I extend an interest-only period?

Sometimes, subject to the lender's assessment at the time.
