Home loan comparison

Buying a home or looking to refinance? The table below features home loans
with some of the lowest interest rates on the market for owner occupiers.


What is an interest-only mortgage?

Interest-only (IO) loans are home loans which delay the repayment of the borrowed amount (the ‘principal’) for a fixed term, usually three to five years. This means for a short period of time, you only have to repay the interest component of the home loan, before it reverts to both principal and interest (P&I) repayments.

Why switch to an interest-only home loan?

Interest-only home loans can be described as “less now, more later” in that your repayments for a few years will be significantly lower, but will be higher than usual once the interest-only period ends. They’re particularly attractive to investors, who can tax-deduct the interest repayments.

As an example of how interest-only loans can be cheaper now, but more expensive later, let’s look at a $400,000 home loan with a 4.00% p.a. interest rate over 30 years:

  • With a 5-year IO period, monthly repayments would be $1,333 before reverting to $2,111 for the remaining 25 years
  • With a simple P&I loan, the monthly repayments remain constant at $1,910

The IO loan will cost the borrower $313,400 in total interest, while the P&I option will cost around $287,500 - a difference of nearly $30,000.

To work out how much your repayments will be with an interest-only home loan, use an interest-only loan calculator.
