How home loan pre-approval actually works

A pre-approval is a lender's conditional agreement to lend you a specific amount, based on documents it has actually assessed. That last part is what separates it from the number a rate comparison website gives you in thirty seconds. One makes you a credible buyer. The other is arithmetic dressed up as an approval, and agents can tell the difference immediately.

What are the three things people call pre-approval?

The middle row is where people get hurt. A system generated approval feels like the real thing, arrives quickly, and can be withdrawn when a human finally looks at the file. If you are going to rely on a pre-approval to bid at auction, it needs to be the third kind, and it is a fair question to ask your broker or lender which one you actually have.

What does a lender look at?

• Identification, and for most lenders that means verified rather than emailed.
• Income evidence: payslips for employees, or tax returns and financials if you are self employed.
• Bank statements, usually three months, which show your actual spending rather than what you estimated.
• Existing commitments, including credit card and overdraft limits whether drawn or not.
• Living expenses, benchmarked against a household expenditure measure if your declared figure looks low.
• Credit history, which is where any enquiries and missed payments surface.

The bank statements are the part applicants underestimate. Lenders read them, and a declared expenses figure that does not match three months of transactions gets replaced with the benchmark. Cleaning up discretionary spending for the three months before you apply is genuinely worth doing.

How long does it take and how long does it last?

With a complete document set, a fully assessed pre-approval commonly comes back within about three to seven business days, though it moves with lender queues. The bottleneck is almost always the applicant assembling documents rather than the assessor reading them.

Once granted it typically lasts three to six months. It can usually be extended, which normally means refreshed payslips and statements rather than starting again. If your circumstances have changed in the meantime, an extension is a reassessment in practice, so tell your broker before the change surfaces on a statement.

What is still conditional?

Every pre-approval is subject to a satisfactory valuation of the specific property, because at pre-approval stage there is no property yet. It is also subject to your circumstances not changing and to the property being acceptable security, which is where unusual property types cause problems.

Does applying hurt your credit file?

A fully assessed pre-approval records a credit enquiry, and enquiries are visible to other lenders. One is unremarkable. Several in a short window looks like someone being declined repeatedly, and it can itself become a reason for caution.

This is the strongest argument for matching your file to the right lender before applying rather than applying to several and seeing who says yes. It is also why we will not submit the same file to multiple lenders simultaneously: it damages the applicant to no benefit.

Why do pre-approvals fall over?

1. 1The valuation came in below the contract price, so the loan to value ratio no longer works.
2. 2Circumstances changed: a job move, a probation period, a new car loan, a fresh credit card.
3. 3The property is not acceptable security, which the pre-approval never covered.
4. 4Declared expenses did not match the bank statements once the full application was assessed.
5. 5It was a system generated approval that did not survive a human assessment.
6. 6It expired quietly while the buyer was still looking.

Five of those six are avoidable with preparation. The valuation is the only one genuinely outside your control, and even that can be anticipated on an unusual property.

How should you prepare in the three months before applying?

Almost everything that weakens an application is visible in the three months of bank statements a lender reads, which means the preparation window is roughly a quarter rather than a fortnight.

1. 1Reduce or close undrawn credit card and overdraft limits, since the limit counts against you whether you use it or not.
2. 2Avoid taking on anything new: a car loan, a buy now pay later facility or a fresh credit card all reduce capacity and appear on statements.
3. 3Bring discretionary spending closer to what you actually declare, because a mismatch gets replaced with a benchmark that is usually worse for you.
4. 4Keep your deposit in one place and let it accumulate, since many lenders want to see genuine savings rather than a recent arrival.
5. 5Do not change jobs if you can avoid it, and if you must, understand that probation narrows your options considerably.
6. 6Get any overdue tax lodgements up to date if you are self employed.

None of that is about presenting a false picture. It is about not handing an assessor avoidable reasons to be conservative, which is what an unexplained pattern in a statement does.

What does a lender see in your bank statements?

More than most applicants expect, and the specific things they look for are consistent. Regular gambling transactions, buy now pay later instalments, dishonoured payments, overdrawn accounts and undisclosed loan repayments all get noticed. So does a declared living expenses figure that three months of transactions do not support.

The right response is disclosure rather than hope. An assessor who finds an undisclosed commitment treats the whole file with more suspicion, whereas one who was told about it upfront simply factors it in. Surprises are what damage an application, not the underlying facts.

What if the property is unusual?

A pre-approval approves you, and says nothing about the property, which is why an unusual security is the most common way a genuinely approved buyer still ends up declined. The categories that cause trouble are consistent enough to list.

• Apartments below a lender's minimum internal floor area, commonly around 40 to 50 square metres.
• Serviced or hotel managed apartments, which are usually treated as specialist security.
• High density buildings where a lender already carries heavy exposure.
• Properties with unapproved structures, such as an enclosed carport or a downstairs conversion.
• Specialist assets such as rooming houses, which are assessed on entirely different policy.
• Rural or large acreage holdings, where lending limits and valuation methods differ.

If the property you are considering falls into any of those, the question to ask before you bid is not whether you are approved. It is whether this specific property is acceptable to the lender who approved you, and that is answerable in advance.

What happens between pre-approval and settlement?

Once you have a contract, the pre-approval converts into a full application against that property. The lender orders a valuation, reviews the contract, and issues formal or unconditional approval if everything checks out. Refreshed payslips are common at this point, and any change in your circumstances since the pre-approval will be picked up.

This is the stage where being honest about changes pays off. A new job, a new liability or a period of leave discovered by the lender looks like concealment; the same fact disclosed by you is just a variable to be assessed. Formal approval is what you need before a finance clause expires, and pre-approval is not a substitute for it.
