Pre-Approval

Home loan pre-approval

Know your budget before you buy

Home loan pre-approval is a lender’s written, conditional indication of how much it is willing to lend you, issued before you have found a property and usually valid for 90 days. Through a broker it typically takes 24 to 48 hours for a straightforward application, up to five business days for a complex one, with a single credit enquiry. It suits anyone about to house hunt or bid at auction, because it sets your budget and shortens the path to full approval.

Illustrative monthly principal and interest repayments over 30 years, before fees and charges. Rates are examples, not offers; your rate depends on the lender and your circumstances. For pre-approval the lender tests the repayment at your rate plus a 3 percentage point buffer, so the amount you are approved for is set by the higher figure. Run your own numbers.

Pre-approval benefits

Know Your Budget
House hunt with a firm price ceiling so you never fall in love with a home you cannot afford.
Move Quickly
When you find the right property, you can make an offer or bid at auction immediately.
Stronger Negotiation
Sellers and agents take pre-approved buyers more seriously than those without finance arranged.
Faster Settlement
Much of the paperwork is already done, so formal approval is quicker once you find a property.

Lenders a broker can compare for your pre-approval

Pre-approval turnaround, validity and credit policy differ by lender. The broker picks the lender whose policy fits your income and deposit before anything is lodged, so only one credit enquiry goes on your file.

Inclusion is editorial reference, not a recommendation. Rates change often, so we only show a rate we captured from the lender's own page in the last 60 days, with a link to that page; otherwise we link to the lender's rate card where it publishes one. The broker you are matched with compares the lenders on their own panel.

* WARNING: This comparison rate is true only for the example given and may not include all fees and charges. Different terms, fees, or other loan amounts might result in a different comparison rate. Home loan comparison rates are based on a secured loan of $150,000 over 25 years.

Home Loan Pre-Approval at a Glance
  • Pre-approval typically lasts 90 days and can usually be renewed
  • Most applications are assessed within 24-48 hours with a broker
  • Only one credit enquiry needed when you use a broker across 50+ lenders
  • Pre-approval is conditional, full approval follows once you choose a property
  • Essential for bidding at auction with confidence

What Is Home Loan Pre-Approval?

Home loan pre-approval (also known as conditional approval or approval in principle) is a written indication from a lender that they are willing to lend you a specified amount based on an assessment of your financial situation. It is not a guaranteed offer of finance, but rather a strong signal that your application is likely to be approved once a suitable property is found and valued.

Pre-approval involves a thorough assessment of your income, expenses, assets, liabilities, and credit history. The lender applies the same serviceability criteria they would use for a formal application, including the APRA-mandated 3% buffer rate. The result is a maximum loan amount that you can use as your budget when house hunting.

In Australia, pre-approval has become an essential step for serious property buyers. Estate agents routinely ask potential buyers whether they have pre-approval, and at auction, it is effectively a prerequisite for bidding with confidence. Without pre-approval, you risk either missing out on properties because you cannot move quickly enough, or committing to a purchase you cannot actually finance.

How the Pre-Approval Process Works

The pre-approval process follows a structured sequence that mirrors much of the formal loan application. Understanding each step helps you prepare and ensures the process moves as quickly as possible.

Step 1: Gather Your Documents

Before you apply, collect all the documentation your lender or broker will need. Having everything ready upfront is the single biggest factor in how quickly your pre-approval is processed. For PAYG employees, this typically includes your two most recent payslips, your latest ATO Notice of Assessment, three months of bank statements, details of any existing debts (credit cards, car loans, HECS-HELP), and identification documents such as your driver licence and passport.

Self-employed applicants need more extensive documentation. This generally means two years of personal and business tax returns, the associated ATO Notices of Assessment, business financial statements (profit and loss, balance sheet), and a recent Business Activity Statement. Some lenders offer low-doc options for self-employed borrowers with strong equity positions.

Step 2: Choose a Lender or Broker

You can apply for pre-approval directly with a bank or through a mortgage broker. A broker offers the advantage of comparing multiple lenders with a single application, which means only one credit enquiry on your file. Different lenders have different credit policies, and a broker can identify which one is most likely to approve your maximum borrowing amount based on your specific circumstances.

Step 3: Submit Your Application

Your broker or lender will lodge the application along with your supporting documents. The lender conducts a credit check, verifies your income and expenses, and assesses your ability to service the loan at the buffered rate. This process typically takes 24 to 48 hours for straightforward applications, or up to five business days for more complex situations.

Step 4: Receive Your Pre-Approval

Once approved, you receive a letter stating the maximum amount the lender is prepared to lend, the applicable interest rate, and any conditions that must be met for formal approval. Common conditions include a satisfactory property valuation, no material changes to your financial position, and the property meeting the lender's acceptable security criteria.

Documents Needed for Pre-Approval

Having the right documents ready before you apply makes the process significantly faster. Here is a comprehensive checklist for the most common applicant types:

PAYG Employees

  • Two most recent payslips showing year-to-date earnings
  • Latest ATO Notice of Assessment (tax return)
  • Three months of bank statements for all accounts
  • Details of existing debts: credit cards, personal loans, car loans, HECS-HELP balance
  • 100 points of identification (driver licence, passport, Medicare card)
  • Evidence of deposit savings (bank statements showing genuine savings)

Self-Employed Applicants

  • Two years of personal tax returns with ATO Notices of Assessment
  • Two years of business tax returns (if applicable)
  • Business financial statements: profit and loss, balance sheet
  • Most recent Business Activity Statements (BAS)
  • ABN/ACN registration details
  • Three months of personal and business bank statements
  • Accountant's letter confirming business trading details (some lenders)

How Long Does Pre-Approval Last?

Pre-approval is not permanent. Most lenders issue pre-approval for a period of 90 days (three months), although some extend this to six months. The time limit exists because your financial circumstances and the lending environment can change, and the lender needs to ensure their assessment remains current.

If your pre-approval is approaching expiry and you have not yet found a property, you can typically apply for an extension or renewal. The lender will usually ask for updated payslips and bank statements and will reassess your application based on current lending policies. If your financial situation has remained stable, renewal is usually straightforward.

Keep in mind that changes during the pre-approval period can affect your renewal. Taking on new debt, changing jobs, or making large withdrawals from your savings could impact the lender's willingness to renew at the same amount. It is wise to maintain financial stability throughout the pre-approval period.

Conditional vs Unconditional Approval

Understanding the difference between conditional and unconditional approval is critical for managing expectations during the buying process. Pre-approval is always conditional, meaning it comes with a set of requirements that must be satisfied before the lender commits fully.

The most common conditions attached to pre-approval include a satisfactory valuation of the specific property you wish to purchase, no material adverse changes to your financial position since the pre-approval was issued, the property meeting the lender's acceptable security criteria (for example, some lenders will not lend against properties smaller than 40 square metres), and all information provided in the application being verified as accurate.

Unconditional approval (also called formal approval or full approval) is issued after all conditions have been met. This means the lender has valued the specific property, verified all your documentation, and is ready to proceed to settlement. Unconditional approval is the green light that confirms your loan will be funded.

Impact on Your Credit Score

Applying for pre-approval involves a credit enquiry, which is recorded on your credit file. A single enquiry has a minor impact, typically reducing your score by 5 to 10 points temporarily. The score usually recovers within a few months.

The risk to your credit score increases if you apply with multiple lenders individually, as each application generates a separate enquiry. Multiple enquiries in a short period can signal financial stress to future lenders and reduce your credit score more significantly. This is one of the strongest arguments for using a mortgage broker, who can assess your application across dozens of lenders with only a single credit pull.

It is worth noting that "soft" credit checks (such as checking your own credit score through a bureau) do not affect your score. Only "hard" enquiries made by lenders or brokers during a formal application process are recorded and can influence your rating.

How far in advance should you get pre-approved?

Apply for pre-approval about four to eight weeks before you expect to start making offers. Pre-approval is typically valid for 90 days, so applying much earlier than that risks it expiring mid-search, while applying the week you find a property leaves no room for the two to five business days most lenders take. If your search runs long, renewing is usually straightforward provided your income and debts have not changed, though the lender will ask for fresh payslips and statements.

Two situations justify going earlier. If you are self-employed, on probation, or have anything unusual on your credit file, start eight to twelve weeks out so there is time to fix problems. And if you are planning to bid at auction, get pre-approval before you register to bid, because there is no finance clause and no cooling-off period once the hammer falls.

What salary do you need for a $500,000 or $700,000 home loan?

Lenders assess what you can repay at your interest rate plus a 3% serviceability buffer, after living expenses and any other debts. As a rule of thumb, a borrower with no dependants and no other debts can usually be pre-approved for roughly five times gross household income. The figures below are indicative at a 6% rate assessed at 9% over 30 years; your own number depends on dependants, existing repayments, credit cards and the lender’s living-expense benchmark.

Loan amountIndicative gross income neededRepayment at 6% (30 years)
$500,000About $95,000 to $110,000About $3,000 a month
$600,000About $115,000 to $130,000About $3,600 a month

Home Loan Pre-Approval FAQs

What would a $500,000 mortgage cost per month?
About $3,160 a month at 6.5% p.a. over 30 years, principal and interest, $2,998 at 6% and $3,327 at 7%. For pre-approval the lender tests it at your rate plus APRA's 3 percentage point serviceability buffer, about $4,204 a month at 9.5%, which is what decides how much you are approved for.
How much will I need to repay monthly on a $1,000,000 mortgage?
About $6,321 a month at 6.5% p.a. over 30 years, principal and interest, or $5,996 at 6% and $6,653 at 7%. The repayment table on this page shows other loan amounts.
How long does home loan pre-approval last?
Most lenders issue pre-approval for 90 days (three months), although some offer up to six months. If your pre-approval expires before you find a property, you can usually renew it provided your financial situation has not changed materially. Renewing may require updated payslips and bank statements, and the lender will reassess based on current lending criteria.
Does pre-approval guarantee I will get the loan?
No. Pre-approval is conditional, meaning it is subject to a satisfactory property valuation, no material changes to your financial situation, and the property meeting the lender's security requirements. Approximately 10-15% of pre-approvals do not convert to full approval, usually due to property issues or changes in the borrower's circumstances between pre-approval and formal application.
Does applying for pre-approval affect my credit score?
Yes, a pre-approval application typically involves a hard credit enquiry, which can temporarily reduce your credit score by 5-10 points. However, this impact is minor and short-lived. The key is to avoid multiple pre-approval applications with different lenders in a short period, as each one creates a separate enquiry. Using a broker means only one credit pull is needed, regardless of how many lenders are assessed.
What is the difference between conditional and unconditional approval?
Conditional approval (pre-approval) means the lender has assessed your finances and is willing to lend up to a certain amount, subject to conditions such as a satisfactory property valuation. Unconditional (or formal) approval means all conditions have been met, including the property valuation, and the lender has committed to providing the loan. You receive unconditional approval after you have found a specific property.
Can I get pre-approved with a low deposit?
Yes. Most lenders will pre-approve with as little as 5% deposit, although you will need to factor in Lenders Mortgage Insurance (LMI) unless you qualify for the First Home Guarantee scheme. Some lenders offer pre-approval with a 2% deposit for eligible borrowers. The lower your deposit, the stricter the assessment criteria tend to be.
What documents do I need for pre-approval?
For PAYG employees, you typically need your two most recent payslips, the latest Notice of Assessment from the ATO, three months of bank statements, a list of assets and liabilities, and identification documents. Self-employed applicants generally need two years of tax returns, business financial statements, and the latest Notice of Assessment. Additional documents may be required depending on your circumstances.
Can I make an offer on a property with only pre-approval?
Yes, and this is one of the main benefits of pre-approval. You can make offers and bid at auctions with confidence, knowing you have a lender willing to fund your purchase up to a specified amount. At auction, having pre-approval is particularly important as there is no cooling-off period. For private treaty sales, you can still include a finance clause as a safeguard.
How far in advance should I get pre-approved for a mortgage?
About four to eight weeks before you expect to make an offer. Pre-approval usually lasts 90 days, so that window gives you time to search without it expiring, while still allowing the two to five business days most lenders need. Start earlier, eight to twelve weeks, if you are self-employed, on probation, or need to tidy up your credit file first, and always have it in place before registering to bid at auction.
What salary do you need for a $500,000 home loan?
As a guide, a single borrower with no dependants and no other debts typically needs gross income of about $95,000 to $110,000 to be pre-approved for $500,000, based on a 6% rate assessed with a 3% buffer over 30 years. For $700,000 the range is roughly $135,000 to $150,000. Dependants, credit cards, car loans and HECS all reduce the figure, and a second income increases it. Use the borrowing power calculator for your own numbers.
How long does it take to get pre-approved?
With a broker, pre-approval can be obtained in as little as 24-48 hours if all documentation is in order. Some lenders offer same-day pre-approval for straightforward applications. Complex situations such as self-employment, multiple income sources, or non-standard properties may take 3-5 business days. Having your documents ready before you apply speeds the process significantly.

WARNING: This comparison rate is true only for the example given and may not include all fees and charges. Different terms, fees, or other loan amounts might result in a different comparison rate. Comparison rates are calculated on a secured loan of $150,000 over 25 years for home loans, a loan of $30,000 over 5 years for car and personal loans, and $50,000 over 5 years for equipment finance, unless the lender states another basis.
