In short: Home loan pre-approval (or ‘conditional approval’) is a lender’s indication of how much they’ll likely lend you, before you’ve found a property. It helps you set a budget and bid with confidence, but it isn’t a guarantee and it usually lasts around three months. Full, unconditional approval comes after you’ve chosen a property and it’s been valued.
Pre-approval is the step that turns ‘I think I can buy’ into ‘I know my budget.’ Here’s what it does and doesn’t do.
What pre-approval is — and isn’t
It’s a conditional yes: the lender reviews your finances and signals what they’d likely lend, subject to conditions (chiefly a satisfactory property and valuation). It is not a final, guaranteed loan — a low valuation or a change in your finances can still affect the final approval.
How long does pre-approval last?
Typically around three months, after which it can be refreshed. That window is your active house-hunting period — worth timing so you’re not re-applying repeatedly.
What you’ll need
- Proof of income (payslips, or tax returns if self-employed).
- ID, and details of your savings/deposit.
- A list of expenses, debts and credit commitments.
Does pre-approval affect your credit score?
It can. Some pre-approvals involve a credit enquiry that’s recorded on your file, and multiple applications in a short time can look like ‘credit hungry’ behaviour to lenders. Applying through a broker who matches you to a suitable lender first helps avoid scattering enquiries. The independent Moneysmart home loans guide explains the application process in neutral terms.
In our experience, first home buyers who organise pre-approval before making an offer usually feel much more in control. They know their likely borrowing range, understand their deposit position, and can move faster when the right property comes up. We often find that once buyers have their payslips, savings history, ID, and expense details ready, the pre-approval conversation can move much faster than they expected.
Pre-approval is built on your borrowing power, so sort that first. See where it sits in the journey in our first home buyer guide.
Frequently asked questions
How long does home loan pre-approval last?
Usually around three months, after which it can be renewed. Use that window as your active house-hunting period.
Is pre-approval a guarantee of a loan?
No. It’s a conditional indication. Final (unconditional) approval still depends on the property valuation and your finances not changing.
Does pre-approval hurt my credit score?
It can, if it involves a credit enquiry — and several applications in a short period can count against you. A broker can help you apply once, to a suitable lender.
