Home Loan Pre-Approval in Australia: What You Need and How It Works

Getting pre-approved for a home loan is the single most important step before you start house hunting. It tells you exactly how much you can borrow, gives you confidence at auctions, and signals to vendors and agents that you're a serious buyer.

Yet many Australians skip this step — or make mistakes that lead to rejection. This guide covers everything you need to know about pre-approval in 2026.

What Is Pre-Approval?

Pre-approval (also called conditional approval or approval in principle) is a written confirmation from a lender that they're willing to lend you a specific amount, subject to conditions. It's not a final loan approval — that comes after you've found a property and the lender completes a valuation.

What Pre-Approval Gives You

• A confirmed borrowing limit — know your budget before you start looking
• Auction confidence — bid knowing you have financing arranged
• Negotiation power — vendors prefer buyers with pre-approval
• Faster settlement — much of the paperwork is already done
• Reality check — understand what you can actually afford, not what you think you can afford

What Pre-Approval Does NOT Guarantee

• Final approval — the lender still needs to value the property and do final checks
• A specific interest rate — rates may change between pre-approval and settlement
• Acceptance of any property — the lender may reject certain property types (e.g., very small apartments, rural properties)

Documents You'll Need

Gathering documents is the most time-consuming part. Having everything ready can cut the process from weeks to days.

For PAYG Employees

Document	Details
Payslips	Last 2–3 recent payslips
Tax returns	Last 1–2 financial years (ATO Notice of Assessment)
Bank statements	Last 3–6 months (savings + transaction accounts)
Employment letter	Confirming role, salary, and employment type
ID	Passport or driver's licence + Medicare card
Existing debts	Credit card statements, personal loan details, HECS-HELP balance
Living expenses	Estimate of monthly expenses (lenders use HEM benchmarks)

For Self-Employed Borrowers

Self-employed applications require more documentation:

Document	Details
Tax returns	Last 2 financial years (personal + business if applicable)
ATO Notice of Assessment	Last 2 years
Business financials	Profit & loss statement, balance sheet
BAS statements	Last 4 quarters
ABN registration	Proof of at least 2 years' trading
Bank statements	Last 6 months (personal + business)
Accountant's letter	Confirming income and business viability

For Investors (Buying Investment Property)

All of the above, plus:

• Existing property details (addresses, values, rental income)
• Existing loan details (balances, rates, repayments)
• Rental appraisal for the property you're buying

How Long Does Pre-Approval Take?

Lender Type	Typical Timeframe
Online/digital lenders	1–3 business days
Major banks (CBA, ANZ, NAB, Westpac)	3–7 business days
Complex applications (self-employed, multiple properties)	7–14 business days
Via mortgage broker	2–5 business days (broker manages the process)

How to speed it up:

1. Have all documents ready before applying
2. Use a mortgage broker who knows which lenders are processing fastest
3. Apply to a single lender (multiple applications trigger credit checks)
4. Ensure your documents are clear, complete, and current

How Long Does Pre-Approval Last?

Pre-approval typically lasts 3–6 months, depending on the lender:

Lender	Pre-Approval Validity
Commonwealth Bank	3 months
ANZ	3 months
Westpac	3 months (extendable)
NAB	3 months
Macquarie	6 months
ING	3 months

If your pre-approval expires, you can usually reapply — but the lender will reassess your financial position, which means updated documents and another credit check.

The Pre-Approval Process: Step by Step

Step 1: Check Your Borrowing Power

Before formally applying, use a borrowing power calculator to get an estimate. This helps you understand if your expectations are realistic.

CREDIGO's free borrowing power calculator uses APRA-compliant serviceability rules to give you an accurate estimate.

Step 2: Choose a Lender or Broker

You can apply directly to a bank or use a mortgage broker:

• Direct to bank: You compare and choose yourself
• Mortgage broker: They compare 30+ lenders and handle the paperwork — at no cost to you

Step 3: Submit Your Application

Provide all required documents. The lender will:

• Verify your identity
• Check your credit score (this creates a "hard inquiry" on your credit file)
• Assess your income and expenses
• Calculate your serviceability (can you afford the repayments?)
• Review your deposit and savings history

Step 4: Receive Your Pre-Approval Letter

If approved, you'll receive a letter stating:

• Maximum loan amount
• Loan type (variable, fixed, or split)
• LVR limit
• Conditions (e.g., "subject to satisfactory valuation")
• Expiry date

8 Common Mistakes That Cause Rejection

1. Applying to Multiple Lenders

Each application triggers a credit check. Multiple checks in a short period can lower your credit score and signal financial stress to lenders. Use a mortgage broker who submits one application to the most suitable lender.

2. Changing Jobs During the Process

Lenders want stable employment. Changing jobs — even for a higher salary — can delay or derail your application. Wait until after settlement if possible.

3. Buy Now Pay Later (BNPL)

Active BNPL accounts (Afterpay, Zip) are treated as ongoing commitments by lenders. They reduce your borrowing capacity. Close them before applying.

4. Credit Card Limits

Lenders assess your credit card limit, not your balance. A $20,000 credit card limit reduces your borrowing capacity by approximately $60,000 — even if the card has a zero balance. Reduce limits or close unused cards.

5. Undisclosed Debts

Don't hide debts — lenders will find them on your credit file. Undisclosed debts lead to automatic rejection.

6. Insufficient Savings History

Lenders want to see genuine savings — regular, consistent savings over at least 3 months. A lump sum gift from parents the week before applying doesn't count as genuine savings (though gifted deposits are accepted with a statutory declaration).

7. Living Expenses

Post-Royal Commission, lenders scrutinise your spending. Excessive spending on dining, subscriptions, gambling, or lifestyle can reduce your assessed borrowing capacity. Consider a 3-month "financial detox" before applying.

8. Applying Too Early or Too Late

• Too early: Pre-approval expires before you find a property, requiring reapplication
• Too late: You find a property but can't move fast enough to secure it
• Sweet spot: Apply when you're 1–3 months away from actively searching

Pre-Approval vs Unconditional Approval

	Pre-Approval	Unconditional Approval
When	Before you find a property	After you've found a property
Property valuation	Not done	Completed
Conditions	Subject to valuation + other checks	None — loan is fully approved
Legal weight	Indicative only	Binding (subject to cooling-off)
How long it takes	1–7 days	3–10 days after valuation
