Home Loan Pre-Approval
What pre-approval really means, how long it lasts, what it does to your credit file, and whether you can rely on it, explained simply by an Adelaide mortgage broker.
Pre-approval is a lender early, conditional indication of how much you may be able to borrow. It lets you search and make offers with a real budget, but the money is only certain at unconditional approval, once a property has been assessed and every condition met.
Pre-approval is a lender early indication of how much you may be able to borrow, based on a first assessment of your situation and subject to conditions. It helps you search and make offers with a clear budget, but it is not a final yes. This guide explains how pre-approval works across the whole journey, from a first borrowing estimate through to unconditional approval, and the detailed questions below go deeper on each part.
The three stages of getting a home loan approved
It helps to see the whole path, because most confusion about pre-approval comes from blurring three different stages. The first is a borrowing estimate, a rough figure based on what you tell a lender or broker, usually with no credit check, useful only for early budgeting. The second is pre-approval, also called conditional approval, where a lender actually assesses you and indicates how much it may lend, subject to conditions. The third is unconditional approval, the real commitment, given once you have a property and every condition has been met. Pre-approval sits in the middle: more than a guess, less than a promise.
Why getting pre-approved is worth it
Pre-approval turns a vague hope into a working budget. It tells you the price range you can realistically shop in, so you do not waste time on homes out of reach or sell yourself short on ones you could afford. It also signals to agents and sellers that you are a serious, ready buyer rather than someone still wondering, which can matter when several people are interested in the same property.
- A clear, realistic budget to search within.
- More credibility with agents and sellers.
- Faster movement once you find the right place.
- An early read on any issues in your situation, while there is still time to fix them.
How long your pre-approval lasts
Most pre-approvals in Australia are valid for around three months, with some lenders allowing up to six. When the period ends it lapses, and if you are still searching it can usually be renewed with updated documents. A renewal is not guaranteed to come back at the same amount, because your situation or interest rates may have shifted in the meantime. The detailed guide on timing and renewing a pre-approval, below, walks through how to handle this.
What pre-approval does to your credit file
A genuine, assessed pre-approval usually involves a credit check, which is recorded as an enquiry on your file and can have a small, temporary effect on your score. That is normal and nothing to fear. The real risk is applying to several lenders in a short period, which can look like credit hungry behaviour. Applying once, to a lender that suits you, is far better than scattering applications and collecting knock backs.
What you need to get pre-approved
Pre-approval goes quickly when your paperwork is ready. In broad terms a lender wants proof of who you are, proof of your income, recent bank statements, details of your debts including credit card limits, and evidence of your deposit and savings. Self employed borrowers usually provide tax returns and business financials instead of payslips. The documents guide below sets out exactly what to prepare.
Why pre-approval is not a guarantee
This is the most important thing to understand. Pre-approval is conditional, so it can change if the property valuation comes in low, the property is not acceptable as security, your circumstances change, or another condition is not met. The lender only truly commits at unconditional approval. That is why you should not waive a finance condition or bid unconditionally at auction on a pre-approval alone.
How a broker makes pre-approval cleaner
Every lender assesses income, debts and expenses a little differently, and each application leaves a mark on your credit file. The value of a broker is in matching your situation to a lender whose policy fits before anything is submitted, so one clean application goes to the right place rather than several going to the wrong ones. For most home loans the broker is paid by the lender, so this guidance generally costs you nothing.
- Pre-approval is an early, conditional indication, not a final yes.
- It usually lasts around three months and can be renewed.
- One assessed application is fine for your credit file, many are not.
- The money is only certain at unconditional approval, once the property is assessed.
- Getting the lender match right the first time is what makes it clean.

Home Loan Pre-Approval: common questions
What is the difference between conditional approval and pre-approval?
For most lenders, conditional approval and pre-approval mean the same thing: an early indication of how much a lender may be willing to lend, based on a first look at your situation and subject to conditions. Neither is a final yes. Unconditional approval, which comes later once a property is assessed, is the real commitment to lend.
How long does home loan pre-approval last in Australia?
Most home loan pre-approvals in Australia are valid for around three months, with some lenders allowing up to six months. The exact period is set by the lender and is usually stated in the approval. When it expires it can normally be renewed with updated documents rather than started again from scratch.
Does applying for pre-approval hurt my credit score?
A single, genuine pre-approval usually involves a credit check, which is recorded on your file and can have a small, temporary effect on your score. That is normal and not something to fear. The real risk is applying to many lenders in a short period, which can look like credit hungry behaviour and weigh against you.
What documents do I need to give a broker for pre-approval?
For pre-approval you generally need proof of identity, proof of income such as payslips or tax returns, recent bank statements, details of your debts and credit card limits, and evidence of your deposit and savings. Self employed borrowers usually provide tax returns and business financials. Having these ready makes pre-approval far faster.
Does a pre-approval guarantee the bank will lend me the money?
No. Pre-approval is a strong indication, not a guarantee. It is given subject to conditions, such as a satisfactory property valuation and no change in your situation. The bank only truly commits at unconditional approval, once the property is assessed and every condition is met. Until then, treat the money as likely, not certain.
How many months of bank statements do lenders check for pre-approval?
Most lenders ask for around three months of recent bank statements for pre-approval, covering your main transaction and savings accounts. Some want more, especially for self employed borrowers or where income is irregular. They read them closely for income, spending, savings and existing debts, so the few months before you apply matter.
Do credit card limits reduce my borrowing capacity even if the balance is zero?
Yes. Lenders generally assess a credit card on its limit, not its balance, because you could draw the full limit at any time. So a card sitting at zero can still reduce how much you are able to borrow. Reducing the limit or closing unused cards before you apply can lift your borrowing capacity.
Can I get pre-approved if I have only been in my job for 3 months?
Often yes. Many lenders can consider you after only a short time in a job, even on probation, especially if you have a solid work history in the same field. Policy varies a lot between lenders, so the key is being matched to one comfortable with your situation. A broker can identify which lenders suit.
How much does it cost to get a home loan pre-approval?
Getting pre-approved generally costs you nothing. Lenders do not usually charge for pre-approval, and when you use a mortgage broker, the broker is typically paid by the lender on settlement, not by you. For most home loans there are no upfront fees to the client. Always confirm any fees before you proceed.
Can I bid at an auction with a conditional pre-approval?
You can, but it carries real risk. At auction the sale is usually unconditional, with no finance condition and no cooling off, while a conditional pre-approval does not guarantee the loan. If you win and your finance is not formally approved, you are still bound to buy. Get as close to unconditional approval as possible before bidding.
What is the minimum deposit needed for pre-approval in Australia?
There is no single minimum. Conventionally a 20 per cent deposit avoids Lenders Mortgage Insurance, while many lenders will lend with as little as a 5 per cent deposit if you pay LMI. Eligible first home buyers can use the First Home Guarantee with a 5 per cent deposit and no LMI, or the Family Home Guarantee with a 2 per cent deposit. You also need funds for other costs.
How does Buy Now Pay Later, HECS and Afterpay affect my pre-approval amount?
HECS-HELP does not appear on your credit file or affect your credit score, but the compulsory repayment is counted as a committed expense, which reduces your borrowing power. Changes in 2025 made this friendlier, and some lenders can now disregard HELP debt being repaid within about a year. Buy Now Pay Later accounts like Afterpay are treated as commitments and can reduce your capacity too.
What property types are excluded or restricted by banks during pre-approval?
Lenders can restrict or decline certain property types as security, even for a strong borrower. Common examples include very small apartments, high density inner city units, studio and serviced apartments, some off the plan purchases, company title properties, rural or large acreage, and properties in certain postcodes. Some are simply harder to finance or need a larger deposit.
How do government grants like the First Home Guarantee affect my pre-approval?
The First Home Guarantee lets eligible first home buyers get a loan with a 5 per cent deposit and no LMI, because the government guarantees the gap to 20 per cent. It does not replace normal pre-approval. You still apply through a participating lender that assesses your income, expenses and the property, and you must meet the scheme eligibility and price caps. Check current rules with Housing Australia.
What happens if interest rates rise after I get my pre-approval?
If rates rise after you are pre-approved, your pre-approval can be affected, because lenders assess you with a serviceability buffer set by APRA at 3 percentage points above the loan rate. A renewed pre-approval may come back at a lower amount. The buffer is designed so you can still cope if rates climb. The rate you actually pay is set later, near settlement.
