The plain English difference
Conditional approval is the lender saying, based on what we’ve seen so far, you look like you fit our criteria. It is often called pre approval. It is a strong signal, but it is not a final green light. Unconditional approval is the lender saying, this specific loan for this specific property is formally approved. That is the point where you are typically in a much safer position.
Why conditional approval can still change
Conditional approval is based on information at a point in time. It often does not fully assess the property until you have chosen one. If your circumstances change, or the property does not meet the lender’s criteria, the lender can reassess.
Common things that can trip people up between conditional and unconditional approval
Valuation is a big one. If the bank values the property lower than the purchase price, the numbers can change quickly. Documentation is another. Missing pages, unclear statements, and inconsistent information can slow down an application and sometimes trigger further checks. Your credit profile matters too. New credit enquiries, increased credit card limits, car finance, or Buy Now Pay Later commitments can all affect borrowing power. Property type can also cause delays. Strata issues, certain construction types, and complicated contracts can lead to more questions from the lender. Finally, timing matters. If your finance clause is too tight, you can run out of days before the lender has time to issue formal approval.
When are you safe to sign? (the practical answer)
In most cases, the safest point is when you have unconditional approval in writing and your conveyancer or solicitor has reviewed the contract and confirmed you understand what you are signing. If you are signing subject to finance, the goal is to reach unconditional approval before that clause expires. That is why you want to work backwards from the contract dates.
Auctions are different
If you buy at auction, the contract is typically unconditional. That means you want to prepare earlier. You want a solid conditional approval, deposit clarity, and a realistic understanding of valuation risk and lender appetite for that property type.
A simple timeline (what usually happens)
First comes conditional approval, where the lender checks income, expenses and credit at a high level. Then you choose a property and the contract is reviewed. Then valuation and final documents happen, and this is where most delays occur. Then unconditional approval is issued. Then settlement happens and you get the keys. The common theme is that staying responsive and keeping your finances stable makes everything smoother.
A quick checklist before you sign anything
Confirm what type of approval you have. Ask what conditions are outstanding. Confirm your finance clause deadlines. Keep your finances stable. Have your conveyancer review the contract.
