What is home loan pre-approval?

Home loan pre-approval is an indication from a lender that, based on the information you have given so far, you appear eligible to apply for a loan up to a certain amount. It is not a promise of finance. Pre-approval generally lasts for 3 to 6 months and does not commit you to a loan, so think of it as a head start on your search rather than a final yes. If you are asking what home loan pre-approval is and how it fits into buying a property, this guide walks through the answer.

Pre-approval, sometimes called conditional approval, gives you a realistic price range before you start making offers. It tells you roughly how much a lender may be willing to lend, which helps you shop with confidence and shows agents you are a serious buyer.

What is home loan pre-approval and how does it work?

When you apply for pre-approval, a lender reviews your finances and tells you the amount you appear able to borrow. To do this, lenders look at your income and financial commitments, your house deposit plus any other savings, and your credit score and credit report.

That assessment is a snapshot in time. The lender forms a view based on the information you provide and the conditions on the day. Because your situation and lending conditions can change, pre-approval does not last forever. It usually stays current for 3 to 6 months, and the exact period depends on the lender, so always check the timeframe stated on your own pre-approval.

Mortgage pre-approval explained simply: it is a conditional step, not the final loan. It shows you appear eligible to apply for a loan up to a certain amount, but full approval still depends on a property valuation and the lender’s final checks against its lending criteria. In other words, how pre-approval works is that the lender gives you a guide to your borrowing range now, then confirms the detail once you have chosen a specific property.

Pre-approval is conditional, not a guarantee

It is worth being clear on this point because it shapes how you should use pre-approval. Pre-approval does not commit you to a loan, and it does not commit the lender to one either. It is an indication, not a contract.

What a lender assesses for pre-approval

To work out the amount you appear able to borrow, lenders weigh up a few things about your financial position. Knowing what they look at helps you prepare.

• Your income and financial commitments, which together show your capacity to manage repayments.
• Your house deposit, plus any other savings you hold.
• Your credit score and credit report, which give the lender a view of how you have handled credit in the past.

A larger deposit reduces the size of the loan you need and can lower your costs. A common savings goal for a house deposit is 20 per cent of the purchase price, plus enough to cover buying costs. A 20 per cent deposit will also avoid you needing to pay lenders mortgage insurance (LMI), a one off cost that applies when your deposit is smaller. First home buyers may be able to buy with a much smaller deposit and still avoid LMI through the Australian Government 5 per cent Deposit Scheme.

If you want a sense of your borrowing range before you apply, working out your borrowing capacity is a useful first move. You can use a borrowing power calculator to get an estimate, then bring that figure into a conversation with a lender or broker. Try the borrowing power calculator below.

Understanding your borrowing power as a first home buyer helps you search within range and reduces the chance of a knock back at full approval.

Where pre-approval sits in the buying process

Pre-approval is one step in a longer sequence. It comes after you have a deposit and a sense of your budget, and before you start making offers. A typical order looks like this.

Getting pre-approval before you make offers helps you search within a realistic price range and shows agents you are ready to act. Just be mindful of the 3 to 6 month window, so it is sensible to line up pre-approval when you are ready to buy rather than far in advance.

How loan features affect what you can borrow

The amount you can comfortably borrow is shaped by the loan you choose, not just your income and deposit. A few features are worth understanding while your pre-approval is live.

When you compare loans, look at the comparison rate. A comparison rate is a single figure of the cost of the loan that includes the interest rate and most fees, so it helps you weigh up options on a like for like basis.

Interest rate type matters too. The two main options compare like this.

Your loan term, which is how long you have to pay off the loan, also affects your repayments and the total interest you pay. None of these features change the fact that pre-approval is conditional. They simply influence the loan that may suit your circumstances and lender criteria once you move to a full application.

How to keep your pre-approval strong while you search

A few habits help your pre-approval stay current and your eventual application run smoothly.

• Keep your finances steady. Avoid large new purchases on credit and try not to change jobs mid search if you can help it.
• Have your paperwork ready, so you can refresh or finalise your application quickly. Knowing the documents needed for a home loan application means there are no surprises.
• Know your real budget. A clear view of your borrowing power helps you search within range and reduces the chance of a knock back at full approval.
• Track your dates. Note when your pre-approval was issued and when it expires so you can plan a renewal before it lapses.
