Interest-Only Investment Loans - Australian Investor Guide 2026

General information only — not financial advice. This content is intended as educational guidance. Consult a qualified financial adviser, mortgage broker, or legal professional before making financial decisions. See our full disclaimer.

An interest-only (IO) investment loan requires you to pay only the interest on the loan balance for a set period - typically 1–5 years - without reducing the principal. The primary reason investors choose IO: mortgage interest is tax-deductible, while principal repayments are not.

Frequently Asked Questions

Can I get an IO loan for an investment property in 2026?

Yes - IO investment loans are still available from most lenders. You'll typically need an LVR under 80% and must demonstrate you can service the full P&I repayment.

Is interest-only better for investment properties?

For high-income investors who can maximise the tax deduction and believe property will appreciate, IO can be part of a strategy. But total interest paid is significantly higher over the loan life.

What happens when the IO period ends?

The loan reverts to P&I repayments on the original balance over the remaining term - with higher repayments than if it had been P&I from the start.
