If you’re planning big bathroom renovations and already have a mortgage, why not consider a top up? Instead of starting from square one with a new loan application, a home loan top up, or home loan increase, allows you to borrow money on top of your existing mortgage.

Although you’re using your home loan, these top ups don’t have to be home-related. You can use your increase on a family holiday, a car you’ve had your eye on, or you may just want to consolidate existing debt. Here’s how it works.

Home loan increase (top up) basics

With a home loan top up, your lender can add additional funds to your existing home loan. This is why some lenders also refer to top ups as “add loans”.  

Top ups increase the total amount of your original home loan, but the home loan product itself never changes. This means that your loan term remains consistent and only your repayment amounts increase. However, if you increase your borrowing to over 80% of the value of your house, Lenders Mortgage Insurance (LMI) may apply.

For example: if you have a $450,000 home loan with 20 years remaining and are set on buying a new car, you may apply for a $15,000 add loan. If successful, your home loan would increase to $465,000, and you’d still have 20 years to repay that amount.

Home loan top up benefits

So, why choose a top up over more familiar lending options?

• Leaning on your home loan can be cheaper. This is because interest rates on mortgages are often lower than rates on personal loans or credit cards.
• Top ups can be more convenient. Having your banking in one place with a single interest rate can simplify managing and planning for repayments. Depending on your goals, you may also be able to borrow more than a typical credit card or personal loan would allow.

Factor in your budget

A top up may have its perks, but you should still carefully consider your long-term budget before increasing your home loan amount. Increasing the sum of your home loan means your repayments will similarly rise until your loan is paid off. Interest paid over the life of the loan can also increase.

Depending on the length of your remaining mortgage, opting for the minimum repayment amount could also make your add loan cost more than a personal loan. With this in mind it’s best to carefully consider your options before making any decisions.

Lenders may also specify a minimum borrowing amount for a top up loan. In the case of Suncorp Bank’s Add Loan, the amount is $10,000. If you’re after a little less, it could be worth looking into a credit card or personal loan instead.

Home loan top up fees

As with other loans, a home loan increase can involve fees. An add loan can carry a renegotiation fee, which should also be factored into your budget. Top ups can only be applied on variable home loans, so if you have a fixed rate home loan, it may not be a good option.
