You have got a text from your broker or your bank saying you are pre-approved, and it feels like the hard part is done. You start looking at open homes with a number in your head and a kind of confidence you did not have last week. That confidence gets ahead of what the paperwork actually supports. Pre-approval is a lender telling you it will probably lend you money, based on what you have told it so far. It is not the same as the money being committed.
The three stages of approval
A home loan can feel approved at more than one point before you own anything. Moneysmart explains pre-approval as an early indication rather than a commitment; formal approval and settlement are separate steps that still have to happen before the money moves.
- Pre-approval (sometimes called conditional approval) is an early assessment. The lender looks at your income, expenses, debts and credit history and gives you an indication of how much it is likely to lend you, subject to conditions it lists but has not yet checked.
- Formal or unconditional approval happens once the lender has done everything it needed to do, including valuing the actual property you want to buy, and is satisfied enough to commit. This is the point where the loan is genuinely yours to use.
- Settlement is when the money actually moves and the property becomes yours.
Pre-approval and unconditional approval get talked about almost interchangeably in casual conversation, but they are not the same event, and the gap between them is where buyers get caught out.
What pre-approval does and does not do
Pre-approval is useful. It tells you, roughly, what a lender thinks you can borrow, which helps you set a realistic search range and shows agents and vendors that you are a serious buyer rather than someone browsing without any financial backing. That is genuinely worth having before you start inspecting properties seriously.
Pre-approval leaves the loan conditional. The lender has assessed you, but not the property, and not the final detail of your finances at the point you actually want to draw down the loan. ASIC's Moneysmart guidance is clear that pre-approval is an indication rather than a guarantee the lender will approve your loan. It is a working estimate, built on the information available at the time, and it comes with conditions attached that still have to be satisfied before it converts into an actual commitment.
The conditions that still have to clear
Moneysmart's guidance sets out, broadly, why those conditions fall into two groups.
The first is about the property. The lender has not yet valued the specific home you want to buy, and it will not lend against a property until it has. If the valuation comes in lower than the price you have agreed to pay, that can change how much the lender will actually lend, or whether it will lend at all. Pre-approval is based on you; the property still has to satisfy the lender in its own right.
The second is about you, checked again. Lenders reassess your financial position at the point of formal approval, more than at pre-approval. If anything about your income, expenses, debts or credit history has changed since you were pre-approved, that gets picked up. Changes in your borrowing position or credit history can shift the outcome, even if they seem minor to you at the time.
Why pre-approval can still fall over
Put those two things together and you can see how a buyer can walk into a purchase feeling approved and still hit a wall. The property might value lower than expected. Your circumstances might have shifted in ways that seem minor day to day but matter to a lender's assessment. Or the pre-approval itself might have run its course. Pre-approval is time-limited, and a lender will not treat an old assessment as current forever. If your search runs long, you may need to go back and have it refreshed, which means the whole assessment happens again with your current information, not the information you gave months earlier.
None of this makes pre-approval pointless. It is a strong indication, and its reliability depends on the property matching what the lender expects and your finances staying steady in the meantime.
How to treat pre-approval when you make an offer
How much protection you have before you are legally committed depends on the type of sale and the state you are buying in. Contract terms, including whether a finance clause applies and what happens if a loan does not convert from pre-approved to formally approved, are set by state-based contracts and consumer affairs rules. They are not set by your lender, and they vary from state to state. If you are buying by private treaty, check with your conveyancer or solicitor whether your contract includes a finance condition before you sign. If you are bidding at auction, assume there is usually no such condition to fall back on, and confirm the position with your state's consumer affairs or fair trading body before you raise a hand.
The practical habit is simple: treat pre-approval as your budget and your credibility with agents. It becomes real money only once the lender has checked the property and your finances again and signed off unconditionally. Keep your finances steady once you have it, do not let it go stale, and before you commit to anything unconditional, ask your lender or broker plainly what is still outstanding before the approval is real.
