Check your credit score

Checking your credit score is a good idea before applying, as it will account for a significant part of your overall creditworthiness in the eyes of the lender. You can check your credit report for free with Compare the Market and receive an overview of your credit history, including your repayment history, late payments or defaults you may or may not be aware of.

Have your documents ready

When applying for a home loan pre-approval, it’s helpful to have your payslips, bank statements and identification on hand. Having these ready can fast-track the home loan process and get you a decision sooner.

Compare your options

Before applying, it is worth comparing interest rates, loan features and lender fees to reduce the likelihood of making multiple applications and protect your credit score. Obtaining a home loan pre-approval can be simpler with the help of our easy online application and Home Loan Specialists, who support you through every step of your homebuying journey at no extra cost.

What is a home loan pre-approval?

A home loan pre-approval is a conditional assessment from a lender that estimates how much you may be able to borrow, based on an initial review of your income, expenses, debts, assets, and credit history. It helps you understand your borrowing power before you go house hunting, but it’s not final approval or a guarantee that your loan will go ahead.

Borrowers typically seek pre-approval to align their home search to a clearer budget and to be better prepared for auctions or making offers.

Pre-approval is generally free and often valid for 60 to 90 days. It’s also obligation-free and not binding, which means the lender can still knock back your final application, and you’re free to pull out or switch lenders.

How do I apply for a home loan pre-approval online?

Applying for home loan pre-approval online usually involves submitting an application through a lender’s website and providing key financial details, such as your income, expenses, assets and debts. You may also need to upload the documents, such as payslips and bank statements, so that the lender can assess your borrowing capacity.

The pre-approval application process is usually straightforward and can be done entirely online, without the need to visit a lender in person. It may be worth having details of your income, expenses, deposit amount and property price range ready to speed up the process.

If you’re unsure what you may need, it’s best to check with the lender.

Does home loan pre-approval expire?

Yes. Home loan pre-approval generally lasts 60 to 90 days, depending on the lender. That’s why it’s best to apply when you’re ready to actively start house hunting, so your pre-approval remains valid when you find the right property.

If your pre-approval expires or if your circumstances change, such as a change in income, expenses or new credit, you’ll generally be able to reapply. Lenders will likely ask for updated financial documents so they can reassess your situation. Depending on your circumstances, you may be pre-approved again for the same amount, more or less.

However, it’s worth keeping in mind that reapplying usually involves a new application and a fresh credit check, which can impact your credit score.
