How to get 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 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.

A home loan pre-approval is almost always conditional. This means the lender has assessed your financial information at a high level, and indicated that you may be eligible for a home loan, but has not yet given full and final approval. Your application will still need to meet certain conditions, such as a satisfactory property valuation, document verification and no major changes to your financial situation to confirm your eligibility.

A home loan pre-approval isn’t mandatory, but having it can help you understand your realistic budget, show sellers you’re a serious buyer, and potentially speed up the final approval process once you find the right property.

Here’s how having pre-approval can help:

• Knowing your borrowing limit helps you focus on properties in your price range and avoid ‘flying blind’ in a competitive market.
• Auction bids are usually unconditional. Having pre-approval in place can help you bid with confidence and avoid overcommitting in the moment. Just keep in mind that pre‑approval is still subject to bank valuation and document checks. So if your finance falls through after a winning bid, you could lose your deposit, face legal action, or be on the hook for any resale shortfall.
• When you make an offer, pre-approval signals to sellers and real estate agents that you’re financially capable and more likely to follow through. Sellers often prefer buyers who already have finance organised.
• In some cases, pre-approval can help shorten the final approval timeline, as much of your financial assessment has already been completed.

System-generated pre-approvals are based on automated assessments of the financial information you provide yourself through an application. They don’t usually involve a full review by the lender’s credit team, and supporting documents typically aren’t verified at this stage.

A system-generated pre-approval is generally quicker to obtain, with some lenders offering online pre-approval in mere minutes. The downside is that these system-generated pre-approvals are less comprehensive and may not fully reflect your eligibility, and could potentially result in a pre-approval being issued even if you don’t meet all home loan criteria.

That being said, this kind of pre-approval has its purpose; many sellers and real estate agents may prefer buyers who already have pre-approval. So, if you’re confident on your odds of receiving full approval for a home loan but don’t have the time to attain a full-assessment pre-approval yet, a system-generated pre-approval could be worth considering.

A fully assessed pre-approval involves the lender’s credit team taking a closer look at your finances and carrying out a more detailed assessment of your personal circumstances. This may include reviewing your income, expenses, assets, liabilities and credit history, as well as verifying supporting documents such as payslips, bank statements, tax returns and other financial records.

The lender may also consider whether you’re a first home buyer, refinancing, or buying an investment property, and assess your application against its lending policies.

This type of pre-approval may take longer, but will generally make for greater confidence and security.

Getting pre-approved for a home loan online usually involves submitting an application through a lender’s website and providing key financial details, such as your income, expenses, assets and debts.

This means it may be worth having details of your income (such as recent payslips), expenses, deposit amount and property price range before starting a home loan pre‑approval application.

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

The time needed to process your application depends on the type of pre-approval. A system-generated option is often done in minutes, whereas a full assessment can take several business days.

When you apply for a home loan through our home loan comparison and application tool, if your application is successful, you’ll come out the other side with a fully assessed pre-approval, meaning you don’t need to apply for it separately!

When you apply for home loan pre-approval, lenders will generally assess your financial situation, credit history and property details to estimate how likely you are to qualify for a mortgage. Lenders will typically look at a range of factors, including your:

• Income and living expenses, which help determine your borrowing capacity and your ability to meet loan repayments.
• Credit history, showing how reliably you’ve met the repayments on debts such as loans and credit cards.
• Existing assets, including savings, investments and other assets that support your application.
• Employment history, with stable and ongoing employment helps to show your income sustainability.

Also assessed are:

• The loan amount you’re seeking and whether it aligns with your income, expenses and overall financial position.
• The property type and location, along with its size, condition and valuation, to ensure it meets the lender’s lending criteria. Some properties or postcodes are considered higher risk and may reduce borrowing capacity.

These factors are similar to those a lender will look at when processing your actual home loan application; the difference is the extent to which they investigate them and the stringency of their lending criteria.

Yes. Home loan pre‑approval typically 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 typically 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.

Yes, it’s possible a lender may knock back your home loan application after they gave you home loan pre-approval. Here are reasons why:

• Your pre-approval wasn’t fully assessed: System‑generated pre‑approvals are based on limited, self‑reported information and don’t involve a full check of your supporting documents. If the details don’t stack up during the final review, the lender may decline the loan.
• Your circumstances change. For example, if you get a new credit card, take out a personal loan or lose your job between getting pre-approval and applying for a home loan, you may find you’re no longer eligible for a home loan from the lender in question.
• Interest rates have risen. If interest rates jump, the maximum amount you can borrow from the lender may contract. This means your new borrowing power may fall short of the property value you were working with, and the lender may assess that you may no longer be able to meet the repayments on the proposed loan amount.
• The property you want to buy is too risky for the lender. Lenders consider certain property types and postcodes as riskier to finance, based on factors such as flood risk. To help avoid nasty surprises when you submit your final loan application, ensure you’re aware of your lender’s excluded properties and suburbs.

While there aren’t any immediate downsides to having a home loan pre-approval in place, it’s important to be mindful of how many lenders you apply with and which type of pre-approval you choose.

Each time you make a pre-approval application, it will likely appear on your credit file as a ‘hard’ inquiry, meaning it’s treated as a formal credit application.

While a single hard inquiry isn’t usually an issue, making several applications in a short period can result in multiple hard inquiries, which may flag you as a higher‑risk borrower. Lenders often interpret this behaviour as desperation for credit or a sign you’re having trouble getting approved, increasing the likelihood of rejection.

Additionally, system-generated pre-approvals can pose challenges later on. Because they often rely on limited information, they may not reflect your true borrowing power, increasing the risk your home loan application won’t meet full lending criteria.
