Mortgage Pre-Approval for First Home Buyers in Australia
Mortgage pre-approval gives you a conditional commitment from a lender for a specific loan amount before you find a property. It tells you exactly how much you can borrow, shows sellers you are a serious buyer, and lets you move quickly when you find the right home. For first home buyers using government schemes, pre-approval is also the stage where you apply for the FHBG or Help to Buy.
What Is Pre-Approval?
Pre-approval (also called conditional approval, approval in principle, or indicative approval) is a written statement from a lender confirming how much they are willing to lend you, based on an assessment of your income, expenses, assets, and debts.
It is not a final approval. The lender still needs to approve the specific property (through a valuation) and confirm that your financial situation has not changed. But it gives you a realistic budget to work with and signals to sellers and agents that you have done the financial legwork.
Why Get Pre-Approved?
Know your budget
No more guessing. Pre-approval tells you the maximum a lender will provide, so you can search within your price range and avoid falling in love with a property you cannot afford.
Show sellers you are serious
A pre-approval letter tells sellers and real estate agents that you have finance lined up. In a competitive market, this can make your offer more attractive.
Move fast on properties
Good properties sell quickly. With pre-approval in hand, you can make an offer immediately rather than waiting weeks for finance approval.
Identify issues early
If there are problems with your application (credit history, insufficient income, too much debt), pre-approval surfaces them before you commit to a property.
What You Need for Pre-Approval
Having your documents ready before you apply will speed up the process considerably. Here is what most lenders require:
For PAYG employees:
- Recent payslips (last 2 to 3, showing year-to-date income)
- Most recent tax return and Notice of Assessment from the ATO
- Bank statements for the last 3 months (all accounts)
- Photo ID (driver licence or passport)
- Letter of employment confirming your role, salary, and tenure
- Details of any existing debts (personal loans, credit cards, HECS/HELP)
For self-employed applicants:
- Last 2 years of personal and business tax returns
- Last 2 years of Notices of Assessment
- Business financial statements (profit and loss, balance sheet)
- ABN/ACN registration details
- BAS statements for the last 12 months
- Bank statements for personal and business accounts (last 3 to 6 months)
How Long Does Pre-Approval Last?
Most pre-approvals are valid for 3 to 6 months, depending on the lender. After that, you will need to reapply with updated documents to confirm your financial situation has not changed.
Keep in mind that conditions can change during the pre-approval period. If interest rates move, if you change jobs, take on new debt, or make large purchases, the lender may reassess your borrowing capacity. The safest approach is to keep your finances stable during this window.
Pre-Approval with Government Schemes
If you are using a government scheme, the pre-approval stage is when you get it set up:
First Home Guarantee (FHBG)
Apply through a participating lender (roughly 49 lenders are on the panel, including all four major banks). Your broker or lender will lodge the FHBG application with Housing Australia as part of the loan process. Since October 2025, there is no income cap and places are unlimited. Learn more about the FHBG
Help to Buy
Applications are made through a Help to Buy Participating Lender at the same time as your loan application. Income must be under $103,000 single / $165,000 couple. Australian citizens only. Learn more about Help to Buy
If you are also using the FHSS, make sure you have requested your determination from the ATO before the pre-approval stage. This way your broker can factor the FHSS funds into your deposit calculation.
What Can Affect Your Borrowing Power?
Lenders assess your ability to repay the loan at a rate higher than the current rate, using APRA’s flat 3 percentage point serviceability buffer, to ensure you can handle future rate increases. The main factors are:
- Gross income: higher income means higher borrowing capacity, but the lender uses your net income after tax
- Existing debts: personal loans, car loans, and credit card limits (even if unused) all reduce what you can borrow
- HECS/HELP debt: compulsory repayments are included in the lender's expense assessment, reducing your borrowing power
- Living expenses: lenders use the higher of your declared expenses or the Household Expenditure Measure (HEM) benchmark
- Number of dependants: children or other dependants increase your assessed expenses
- Credit history: defaults, late payments, or too many recent credit enquiries can hurt your application
- Employment type: permanent full-time is preferred, while casual and contract workers may face stricter scrutiny
A good mortgage broker can help you understand exactly how these factors apply to your situation and suggest ways to improve your borrowing capacity before you apply.

Frequently Asked Questions
Does pre-approval guarantee I will get the loan?
No. Pre-approval is conditional. The lender still needs to approve the specific property you want to buy (through a valuation) and verify that your financial situation has not changed since the pre-approval was issued. Avoid changing jobs, taking on new debt, or making large purchases during this period.
Does applying for pre-approval affect my credit score?
Yes, a full pre-approval typically involves a credit check, which creates a hard enquiry on your credit report. Multiple hard enquiries in a short period can lower your score. Some lenders offer a preliminary assessment without a hard credit check. Ask your broker about this option.
Can I get pre-approved with HECS/HELP debt?
Yes, but HECS/HELP debt reduces your borrowing power. Lenders include your compulsory HECS repayments in their assessment of your expenses, which lowers the amount they will lend you. Be upfront about your HECS balance so your broker can factor it in accurately.
How long does it take to get pre-approved?
A straightforward application with all documents ready can be pre-approved in 1 to 5 business days. More complex situations (self-employment, multiple income sources, or unusual assets) can take 1 to 3 weeks. Having all your documents prepared before you apply speeds up the process significantly.
