What is an interest only home loan?

An interest only home loan requires you to only repay the monthly interest on the amount borrowed (the principal) for a set term of 1-5 years. No repayments are required to reduce the principal amount borrowed, which means the loan balance doesn't reduce at all.

At the end of the interest only period, the loan will change to a 'principal and interest' loan where you'll start repaying the amount borrowed, as well as interest on that amount.This will mean your loan repayments will be higher than if you had of made principal and interest repayments at the beginning of the loan.

Benefits of interest only home loans

We've listed out a number of reasons why investors choose to take out a BOQ interest only home loan.

Interest only benefit

More cash flow

With lower repayments for the initial term, you'll have more money on hand to make improvements to your investment property.

Who are interest only home loans suitable for?

Interest only home loans are a popular choice for property investors who prefer not to pay down the loan at the start but instead use the extra money to make improvements to the property and hopefully increase its value. Making further improvements to the property will hopefully make the home more appealing to renters and increase your rental income.

As always, if you need any guidance in deciding what loan is the right for you, please contact your BOQ home lending specialist on 1300 55 72 72 or find your local branch.

What do I need to know about interest only home loans?

Comparing loans can be like comparing apples with oranges, so it’s important that you consider all the loan features before deciding if it’s the right one for you and your investment goals. 

 

  • Once the interest only period is over, you will need to make payments on both the principal and interest within the remaining loan term. This will mean your repayments will be much higher than it would be if principal repayments were made at the start of the loan term.
  • The interest rate for an interest only home loan may be higher than the interest rate for principal and interest rate home loan.
  • Interest only terms are also available on fixed rate loans - the interest only term must match the fixed rate term.
  • You can have a mortgage offset linked to your home loan if you choose an eligible variable loan like our Clear Path Variable Interest Only Home Loan.
  • For a construction loan, during the construction period you only need to make interest only repayments.

FAQs

  • How do Interest Only mortgages work?

    An Interest Only home loan means you only repay the monthly interest on the amount borrowed for a set term of one to five years. No repayments are required to reduce the principal amount borrowed, which means the loan balance doesn't reduce.

    At the end of the Interest Only period, the loan will change to a 'Principal and Interest' loan and you'll start repaying the amount borrowed, as well as interest on that amount. Your loan repayments will be higher for the remainder of the loan term than they would have been if you had made Principal and Interest repayments from the beginning of the loan, because you will have less time left in the loan term to pay off the principal amount.

  • What happens when my Interest Only term ends?

    When you applied for your Interest Only loan, you would have nominated the period of your Interest Only term. This is usually 1 to 5 years. At the end of your Interest Only term, your loan automatically changes to a variable rate loan with Principal and Interest repayments. As a result, your repayment amount may change and is likely to be higher. But that’s not the end of the story. You do have other options. 

  • What are my options after my Interest Only term ends?

    While your loan will automatically revert to a variable rate loan with Principal and Interest repayments, you’re not locked into that. Depending on what is important to you, other potential options could include:

    • extending your Interest Only term (subject to assessment and approval)
    • switching to a fixed rate term
    • automatically reverting to a variable rate with Principal and Interest repayments.
    • If you’re not sure whether to switch to a fixed rate or stay on a variable rate, you can even split your home loan so part of it is fixed and the other part is variable.

    With all these options, it can be a little confusing to figure out what’s right for you. But don’t worry, we’ll get in touch with you before your Interest Only term expires (around 30 to 60 days prior) with more information about the options you can consider and the steps you’ll need to take.

  • What is the difference between an Interest Only and Principal and Interest home loan?

    With Interest Only home loans, you only repay the monthly interest on the amount borrowed for a set term of 1 to 5 years. No repayments are required to reduce the principal amount borrowed, which means the loan balance doesn't reduce.

    Principal and Interest home loans repayments include a component that goes towards paying down the principal balance of the loan (the amount you borrowed) and a component that goes towards interest (the cost of borrowing).
