Topping up your home loan

Where do I start?

Whether you’re renovating, buying a new car, planning a wedding or consolidating debts – you could get that little bit extra you need from your current home loan.

It's important that you consider the value gained from what the top up is used for and how you choose to structure this with your home loan. You can choose to add it to your existing loan, meaning you pay it off over a longer period, or have a separate loan that you can pay off sooner. 


Topping up your home loan

A top up means borrowing more on top of your existing home loan, something that’s possible when your home has increased in value since you first took your loan out, or you've created equity through paying off a portion of your home loan. This means you can use that equity to borrow against.

When considering the value of your top up, you’ll want to consider how that impacts you in the long term. For example if you’re completing home improvements, the value this adds to your property is experienced over many years so you could pay this top up off over a longer period of time. You may wish to seek advise as to whether other options may suit you better (such as a separate home loan that you can pay off over a shorter period).

Adding to your existing home loan will increase your repayments and increase the time it takes to pay off your home loan, so consider if topping up is right for you.

Benefits of a home loan top up

You’ll get a lower interest rate than you’d get from a personal loan or credit card.

If you’re looking to top up your home loan for a renovation project, you may consider whether a building loan is suitable for you, if the work is significant, requires a building consent and progress payments. Talk to one of the team to see what option is best for you.

How much can I borrow?

The amount you can borrow will depend on a number of things, including the equity you have available in your home and your personal finance situation. You’ll need a minimum of 20% equity in your home to be eligible for a home loan top up, or more if your property is an investment.
