Borrowers choose interest-only loans for a variety of reasons, but the main effect of choosing ‘IO’ is lowering your mortgage repayments. While you don’t chip away at the principal, IO loans can be used to minimise costs while settling into a property, finding tenants, or to realise capital growth then sell later to pay off the home loan in its entirety.

However, not all lenders are made equal when it comes to interest-only periods. Some may only allow for a few years, while others allow for a lot longer - it can also differ based on whether you’re an owner occupier or investor, plus how much of a deposit you have saved up.

Banks' and Lenders' Maximum Interest-Only Periods

Many institutions Savings.com.au spoke to had a maximum IO period of about five years however there were some variations. You’ll also have to double check if the IO period applies only to construction loans. Of the near 40 lenders Savings.com.au reached out to, the only lenders to not respond in time for deadline was Westpac.

Popularity of interest-only home loans

Interest-only loans now make up a relatively small portion of lending in Australia. Full-year results from Australia’s largest bank, Commonwealth Bank, showed interest-only home loans made up just 12% of its $516 billion total home loan portfolio in June 2021, down from 15% of $498 billion in December 2020, and 16% of $485 billion in June 2020.

In 2017, the Australian Prudential Regulation Authority (APRA) placed limitations on the amount of IO loans banks can provide new customers. Interest-only loans could amount to only 30% of new residential loans, with tough restrictions on IO loans to customers over 80% LVR. However APRA removed this rule in late 2018. Prior to the crackdown, ‘IO’ loans made up nearly 40% of the mortgage market, according to the Reserve Bank, with 23% of owner occupiers taking out IO loans, and nearly two-thirds of investors. Even with restrictions eased, IO loans make up a small portion of the market.

Pros of a longer interest-only period

  • Lower repayments: You’ve just paid stamp duty, conveyancing fees and a deposit - chances are you’re feeling the pinch a bit. Interest-only payments lower your mortgage repayments while you find your feet, or find tenants if an investor.

  • Tax considerations for investors: Investors can claim a number of items on their investment property, including mortgage interest against their total income. By choosing an IO loan and claiming expenses, chances are you could spend near zero on mortgage repayments as an investor for a few years.

  • Realise capital growth: If you’re looking to sell a few years down the track, given the way Australian property prices have gone, you could realise strong capital growth while paying IO and keeping that cash you’d have paid on the principal for other expenses. Then when it comes time to sell you can pay off the loan in full. Of course, capital growth isn’t guaranteed.

Cons of a longer interest-only period

  • Don’t chip away at principal: You’re not actually chipping away at the home’s value - only treading water paying interest every fortnight or month, and hence not building any equity this way.

  • Higher interest rates: Recent RBA data shows the average interest rate on outstanding owner occupier IO loans is 4.11% p.a., while for investors it’s 4.29% p.a. - this is much higher than loans paying principal & interest.

  • High revert rates: After the IO period ends, you might be automatically placed on what’s called a ‘revert rate’, which is often much higher than a bank’s discounted variable rate. You can refinance, but you’ll have to be diligent.

  • Bigger deposits required: IO loans often require a larger deposit to account for the additional risks and equity concerns. Often IO loans require a minimum 20% deposit, and sometimes up to 40%.

  • Capital growth concerns: The risk with IO loans is that capital growth isn’t guaranteed. If property prices head south and you haven’t built any equity (as you would by paying the principal), you could be in a bit of pain if it comes time to sell.
