Fancy a home loan top-up?

If you're feeling a little thirsty for some extra cash and you've got the equity in your home, this might be the option for you.

Key takeaways

  • If you've been paying off your home loan, you can use the equity you've built to borrow extra money.
  • You can use the money from a home loan top-up for anything you like.
  • When you borrow more money from a home loan top up, your home loan repayments will increase.

What is a home loan top-up?

A home loan top-up is a way of increasing the amount of your home loan so you can borrow some extra money. If you've been paying off your loan and building equity in your home, then your lender may let you 'top up' your loan in this way.

A home loan top-up often works out cheaper than using a personal loan or a car loan. But adding to your home loan means your monthly repayments will increase and you'll pay more in interest over time.

How does a home loan top up work?

As you pay off your home loan you're increasing the amount of the property you actually own. This is called equity. (Note that if you've been making interest-only repayments your equity won't increase much because you haven't actually started repaying the loan.)

If your lender lets you top up your home loan for the extra cash you can use this for any reason you like. You could renovate your house, take a holiday, or buy a new car.

Home loan top-up scenario

  • You bought a $900,000 home with a 20% deposit. Your loan amount was $720,000.
  • A few years pass and your home is now worth $950,000 and your loan has shrunk to $691,000.
  • You now have $259,000 in equity (that's the current home value minus your remaining loan amount).
  • You want to borrow $20,000 to spend on some home upgrades.
  • Your lender agrees and you top up your loan from $691,000 to $711,000.

Lenders set a cap on how much equity you can access. Some will lend up to 80% of your property's value, but it depends on your individual circumstances.

Can you top up a fixed rate home loan?

Topping up a variable rate home loan is usually straightforward. These loans are quite flexible and typically allow you to make extra repayments.

Fixed rate home loans are a different story. Often, lenders limit extra repayments on these loans. And topping them up is harder as well. Some lenders only allow top-ups on variable loans. But it really depends on the lender.

The pros and cons of a home loan top up

Pros

  • Cheaper way to borrow money compared to personal loans, car loans or credit cards.
  • Keeps your debt in 1 account with 1 repayment.
  • You don't have to spend the entire amount and you're only charged interest on the amount you use.

Cons

  • The equity in your property reduces.
  • Your mortgage repayments will increase.
  • The extra top up adds to your mortgage, so the longer loan term you have left the more extra interest you'll pay.

How do I get a home loan top-up?

Number 1

Speak to your lender.

Check if your lender is able to provide a home loan top up. You'll then need to check you are able to top up your home loan with the equity you have.

Number 2

Apply for a home loan top up.

It might be as simple as continuing that first conversation with your lender. Otherwise, you might be able to apply through your lender's online or app facilities. Some lenders charge an establishment or application fee, so be sure to check any fees involved.

Number 3

Check serviceability.

Sit back and wait while your lender checks the equity you have and whether they believe you'll be able to continue meeting the extra repayment amounts. It may conduct a valuation on the home to check its current value. This will determine your loan-to-value ratio.

Number 4

Get your answer!

Once the lender has gone through the application and checked your serviceability, you'll be given the extra funds through a redraw facility. You can withdraw the cash as you need it.

Once you've spent the extra money you've borrowed, your repayments will increase. Alternatively, your lender may agree to let you extend your loan term instead. This means your repayments stay the same but you take a bit more time to repay the loan.

Either way, you end up paying your lender more interest.

What are the alternatives to topping up my home loan?

The alternatives depend on what you're using the funds for. But here are some solutions:

  • A personal loan - Personal loans will give you the same flexibility of choosing what you need the loan for. Although it will have a higher interest rate than your home loan, you'll pay it over less time and so will pay less interest. You'll need to make sure you can make the extra loan repayment on top of your home loan.
  • A car loan - Only really an alternative if you were wanting to buy a new car! As with personal loans, they'll have a higher interest rate but you'll pay it off much faster.
  • Refinance your home loan - Switching to a new loan, and possibly a new lender, is a good time to try to borrow a little more money. This is more complicated than a top-up. But you can switch to a better home loan at the same time. A loan with a lower interest rate could save you a lot of money.
  • A line of credit or home equity loan - This functions much like a home loan increase, giving you access to funds based on the equity in your home. A line of credit differs in that it's a separate loan account, requiring a separate repayment.
  • A credit card - Depending on the size of your purchase you could also apply for a credit card. However, credit cards generally carry very high interest rates relative to home loans, and, depending on your credit limit, may offer a lower amount of funds for your purchase. If you choose to use a credit card for a major purchase, you'll need to ensure you're disciplined to pay it off as quickly as possible.
