Can Your Home Loan Pre-Approval Expire? What Sydney Buyers Need to Know
How Long Does Home Loan Pre-Approval Last and What Happens If It Expires?
You receive home loan pre-approval, establish your budget and start searching for property.
But three months later, you still haven’t found the right home.
Is your pre-approval still valid?
Possibly not.
Home loan pre-approvals generally have an expiry date, and many Australian lenders currently issue them for around 90 days or three months.
For example, CommBank and NAB currently state that their conditional pre-approvals are valid for 90 days, while ANZ says pre-approval generally lasts around three months. Westpac also states that most pre-approvals, including its own, are valid for three months.
That means Sydney buyers who spend several months searching for the right property may need to have their finance reassessed before making an offer or bidding at auction.
And even while your pre-approval is still within its expiry date, it is important to understand one thing:
Pre-approval is not the same as unconditional home loan approval.
What Is Home Loan Pre-Approval?
Home loan pre-approval, sometimes called:
- conditional approval
- approval in principle
- indicative approval
is an indication from a lender that it may be prepared to lend you up to a certain amount based on the information assessed at that time.
The lender may consider information such as:
- your income
- employment
- living expenses
- deposit
- existing home loans
- personal loans
- car finance
- credit cards
- HELP debt
- dependants
- credit history
- proposed purchase price
Pre-approval can give you a clearer idea of your potential borrowing capacity before you begin seriously searching for property.
However, it is generally still subject to conditions.
ANZ, for example, makes clear that pre-approval is an indication of how much it may be willing to lend rather than a guarantee, and the eventual property must also be acceptable security to the lender.
How Long Does Home Loan Pre-Approval Last?
There is no single expiry period that applies to every lender.
However, around 90 days or three months is common.
As of 2026:
CommBank
Conditional pre-approval is stated as being valid for 90 days.
NAB
NAB states that its conditional approval certificate is valid for 90 days.
Westpac
Westpac says most pre-approvals are valid for three months, including its own.
ANZ
ANZ states that pre-approval generally lasts for around three months, assuming your circumstances do not change.
Other lenders may have different policies.
The expiry date on your actual pre-approval should always be checked rather than assuming you automatically have 90 days.
Why Does Home Loan Pre-Approval Expire?
Pre-approval is based on a snapshot of your financial circumstances at a particular point in time.
But your financial position can change.
So can:
- interest rates
- lender credit policies
- serviceability calculations
- your income
- your expenses
- your debts
- your employment
- your deposit
- your credit profile
A lender therefore generally cannot rely indefinitely on an assessment completed months earlier.
When a pre-approval is renewed, the lender may need to confirm that the information originally provided is still accurate.
For example, CommBank’s current renewal process can involve updating income and financial commitments and providing documents to reverify income or debts before the application is resubmitted.
What Happens If Your Pre-Approval Expires?
An expired pre-approval does not necessarily mean you can no longer borrow.
It generally means your borrowing position needs to be reviewed again.
Depending on the lender, this could involve:
- renewing the existing pre-approval
- refreshing financial information
- providing updated payslips
- providing updated bank statements
- confirming current living expenses
- updating liabilities
- completing another serviceability assessment
- or submitting a new pre-approval application
ANZ states that if its pre-approval expires before you have signed a contract and you still want pre-approval in place, another pre-approval application is required.
Westpac says its approval in principle can generally be renewed at the end of the 90-day period where required, provided the borrower’s financial circumstances have not changed.
The exact process therefore depends on the lender.
Can Your Borrowing Power Change When Pre-Approval Is Renewed?
Yes.
This is one of the most important things Sydney buyers need to understand.
Your original pre-approval may have indicated that you could borrow:
$800,000
But three months later, your borrowing capacity could potentially be:
higher, lower or approximately the same.
Why?
Because the lender may reassess your application using your current circumstances and current lending policy.
What Could Reduce Your Borrowing Power?
Several things could potentially change between your original pre-approval and your reassessment.
1. Your Income Has Changed
If your income falls, your borrowing capacity could also fall.
Examples could include:
- changing jobs
- reducing working hours
- losing regular overtime
- receiving lower commissions
- moving from permanent employment to casual employment
- starting a new business
- taking parental leave
Your employment situation is an important part of most home loan assessments.
ANZ specifically notes that changes to income, expenses or employment can affect how much a lender may be prepared to lend.
2. Your Expenses Have Increased
Your lender considers the amount of income available after household expenses and financial commitments.
If your expenses have increased since the original application, your serviceability position could change.
This could include:
- increased rent
- childcare costs
- insurance
- school expenses
- subscriptions
- transport costs
- general household spending
- additional dependants
Small changes do not automatically mean your borrowing capacity will collapse, but your current expenses form part of the lender’s assessment.
3. You Have Taken Out New Debt
Imagine you receive pre-approval and then finance a new car.
That additional monthly commitment may reduce the income available to service your proposed mortgage.
The same can apply to:
- personal loans
- buy now, pay later commitments
- additional credit cards
- increased credit limits
- investment loans
- other financial liabilities
If you are actively looking to buy property, consider the potential home loan impact before taking on significant new debt.
4. Your Credit Card Limits Have Changed
Credit cards can affect borrowing capacity even when the outstanding balance is relatively low or paid off each month.
A lender may consider the available credit limit when calculating your commitments.
Opening additional credit facilities between pre-approval and purchase may therefore change your serviceability position.
5. Interest Rates Have Changed
Interest rates can affect borrowing capacity because lenders assess whether you can afford the proposed debt using a serviceability assessment rate.
If rates rise, the assessment rate may also rise.
That can potentially reduce borrowing capacity.
Conversely, lower rates may improve serviceability for some borrowers, although the final result still depends on the lender’s policy and the applicant’s overall circumstances.
This is why a borrowing-capacity result calculated several months ago should not necessarily be treated as permanent.
6. Lender Policy Has Changed
Even if your personal circumstances remain exactly the same, lenders can change their policies.
For example, a lender may change:
- how certain income is assessed
- how rental income is treated
- acceptable debt-to-income levels
- serviceability assumptions
- property restrictions
- documentation requirements
A pre-approval is therefore based on both your circumstances and the lender’s policies at that point in time.
Can Your Borrowing Power Increase When You Renew Pre-Approval?
Potentially.
Not every reassessment results in a lower borrowing capacity.
Your position could improve if, for example:
- your salary increased
- you repaid a personal loan
- you reduced unnecessary credit limits
- you saved a larger deposit
- interest rates moved lower
- an existing liability was cleared
- your income history became stronger
The new assessment needs to be completed before you know the actual result.
Does Pre-Approval Guarantee Final Home Loan Approval?
No.
This is probably the most important distinction in the entire home-buying process.
A pre-approval relates primarily to your financial position and the information available to the lender at that stage.
Once you find a property, the lender may still need to assess things such as:
- the purchase price
- the bank valuation
- property type
- location
- title
- apartment size
- building characteristics
- loan-to-value ratio
- updated financial information
- final credit checks
- any conditions attached to your pre-approval
CommBank, for example, states that after a buyer signs a contract, further checks may include a property valuation, credit checks and building documents before formal approval is provided.
NAB similarly notes that final approval can involve the bank valuing the property being purchased.
So:
Pre-approved borrower does not automatically mean approved property.
The Property Can Still Cause a Finance Problem
This connects directly with another issue Sydney buyers should understand.
You may still experience difficulty obtaining final approval if the property itself does not meet lender requirements.
Potential examples include:
- very small apartments
- studio apartments
- serviced apartments
- unusual titles
- significant building defects
- problematic strata schemes
- unacceptable security types
- properties with limited resale markets
- a bank valuation below the purchase price
This is why property due diligence and finance should not be treated as completely separate processes.
What If the Bank Valuation Is Lower Than the Purchase Price?
Pre-approval also does not guarantee that the lender will agree with the price you have negotiated.
Imagine you have pre-approval based on a purchase around:
$900,000
You find a property and agree to pay:
$900,000
But the bank valuation comes back at:
$850,000
Depending on your deposit and loan structure, the lower valuation could mean you need to contribute additional money toward the purchase.
In some cases, the finance strategy may need to be reconsidered entirely.
A pre-approval therefore should not be interpreted as the lender agreeing to whatever price you ultimately negotiate.
Sydney Auction Buyers Need to Be Particularly Careful
This is especially important in Sydney, where many properties are sold at auction.
In NSW, there is no cooling-off period when you buy residential property at auction. The successful bidder is expected to sign the contract and pay the deposit, generally on the spot.
That means bidding at an auction based on an expired or outdated pre-approval can create significant risk.
Before bidding, buyers should ideally have:
- their pre-approval current
- their financial circumstances reviewed
- a clear maximum purchase budget
- the contract reviewed by their solicitor or conveyancer
- appropriate property due diligence completed
- an understanding of any lender or valuation risks
NSW Government guidance warns that a successful auction bidder must be ready to exchange contracts and complete the sale, because auction purchases do not have the normal cooling-off period.
What About Buying by Private Treaty in NSW?
Residential property purchased by private treaty in NSW generally has a five-business-day cooling-off period, although it can be waived, reduced or extended in certain circumstances.
Buyers are sometimes asked to waive the cooling-off period by providing a Section 66W certificate through their solicitor or conveyancer.
If you are being asked to waive your cooling-off rights, make sure you understand the consequences and obtain appropriate legal advice before proceeding.
The NSW Government specifically recommends seeking advice before waiving the cooling-off period.
What If Your Pre-Approval Is About to Expire?
Don’t wait until you find the perfect property to discover your pre-approval expired last week.
If you’re still actively searching, contact your mortgage broker or lender before the expiry date.
Review:
- Your current income
- Your employment
- Your expenses
- Your credit cards
- Your existing loans
- Your deposit
- Any new liabilities
- Your current borrowing capacity
- Your lender’s current policy
- Your pre-approval expiry date
This gives you an opportunity to identify any changes before making an offer.
Should You Apply for Pre-Approval Too Early?
Usually, there is little benefit in obtaining pre-approval many months before you are genuinely ready to buy.
If the approval lasts around 90 days and you are not planning to purchase for another six months, it may expire before your serious property search even begins.
ANZ specifically notes that obtaining pre-approval too early may mean having to repeat the process.
There can also be credit-file considerations.
Westpac notes that pre-approval applications can be recorded in a borrower’s credit history and warns against making multiple pre-approval applications with different lenders at the same time.
The objective should not be to apply to as many banks as possible.
The objective is to understand your circumstances, identify appropriate lender options and obtain pre-approval when you are genuinely approaching the buying stage.
A Better Timeline for Sydney Property Buyers
A practical sequence may look something like this:
Step 1: Review Your Borrowing Position
Understand your income, debts, deposit and indicative borrowing capacity.
Step 2: Establish Your Comfortable Buying Budget
Your maximum borrowing capacity and the amount you personally want to spend do not have to be the same.
Step 3: Obtain Pre-Approval
Once you are genuinely ready to begin the property search, obtain an appropriate pre-approval where suitable.
Step 4: Start Searching
Focus on properties that fit both your financial budget and your purchasing criteria.
Step 5: Monitor the Expiry Date
If you approach the 90-day mark without purchasing, review your finance again.
Step 6: Reassess Before Making an Offer or Bidding
Make sure nothing material has changed.
Step 7: Get the Property Checked
Review the contract, property, comparable sales, strata information where relevant and potential lender-security issues.
Step 8: Progress to Formal Approval
Once the property is secured, provide the required information to the lender so the application can proceed toward unconditional approval.
Don’t Let the Pre-Approval Amount Become Your Target Price
There is another mistake buyers sometimes make.
The lender says:
“You may be able to borrow $850,000.”
The buyer immediately thinks:
“Great. I’ll borrow $850,000.”
But maximum borrowing capacity and comfortable borrowing capacity are different things.
Your own budget should consider:
- mortgage repayments
- council rates
- strata levies
- insurance
- maintenance
- childcare
- transport
- lifestyle costs
- future plans
- emergency savings
- possible rate changes
Pre-approval should help establish a financial boundary.
It should not automatically become a target that you need to spend.
Has Your Pre-Approval Expired? Don’t Panic
If your home loan pre-approval has expired, it doesn’t automatically mean your property plans are over.
You may simply need to have your position reassessed.
If your circumstances have remained stable, renewing the approval may be relatively straightforward with some lenders.
If your circumstances have changed, the review can give you an updated understanding of what you can realistically borrow before you commit to a property.
What you don’t want to do is assume an old approval is still valid and bid or exchange contracts based on outdated information.

Frequently Asked Questions
Can home loan pre-approval expire?
Yes. Home loan pre-approvals generally have an expiry date. Around 90 days or three months is common among major Australian lenders, although the exact period varies by lender.
How long does mortgage pre-approval last in Australia?
Many lenders use approximately 90 days or three months, but you should check the expiry date and conditions provided by your individual lender.
What happens when my pre-approval expires?
You may need to renew, refresh or reapply. The lender may request updated information about your income, expenses and financial commitments before issuing another pre-approval.
Will my borrowing power stay the same when I renew?
Not necessarily. Changes in your income, expenses, debts, interest rates, employment or lender policy could potentially change your borrowing capacity.
Can my borrowing power increase after my pre-approval expires?
Potentially. For example, your position may improve if your income increases, you repay debts, increase your deposit or other parts of your financial circumstances improve. The lender must reassess your current circumstances.
Can I make an offer with expired pre-approval?
You can make an offer, but relying on outdated borrowing information creates additional finance risk. Before committing to a purchase, it is sensible to have your current finance position reviewed and obtain legal advice regarding the contract conditions.
Does pre-approval mean my home loan is guaranteed?
No. Pre-approval is generally conditional. The lender may still need to assess the property, valuation and your updated circumstances before providing formal or unconditional approval.
Can a property be rejected even if I’m pre-approved?
Yes. A lender still needs to be comfortable with the property being offered as security. Property type, valuation, location and other security issues can affect final approval.
Can I bid at auction with pre-approval?
Pre-approval can form part of preparing to bid, but it is not a guarantee of final finance approval. This is particularly important in NSW because auction purchases have no cooling-off period.
Should I renew my pre-approval before it expires?
If you are still actively searching and the expiry date is approaching, speak with your mortgage broker or lender early so you understand what is required to maintain an up-to-date borrowing position.
