What is pre-approval?
Pre-approval is a lender’s assessment of how much they are willing to lend you, made before you have found a property. You provide your financial details, the lender reviews them, and if you meet their criteria they issue a pre-approval, usually as a letter or certificate stating the maximum amount they will lend.
You will hear it called by a few different names, which all mean essentially the same thing: pre-approval, conditional approval, or approval in principle. The word conditional is the key one. Pre-approval comes with conditions attached, the biggest being that the specific property you eventually choose still has to pass the lender’s checks. It is a strong indication, not a locked-in guarantee.
Why you need pre-approval
Pre-approval is not strictly compulsory, but going without it puts you at a real disadvantage. Here is what it does for you.
It tells you your real budget
Without pre-approval, you are guessing at what you can afford. With it, you have a clear ceiling, so you only look at homes you can actually buy. That saves you from falling for a place that is out of reach, and from wasting weeks looking in the wrong price bracket.
It lets you act fast and bid with confidence
In a competitive market like Newcastle and the Hunter, the right home does not wait. When you are pre-approved, you can make an offer or bid at auction knowing your finance is lined up. Buyers without pre-approval often miss out simply because they cannot move quickly enough.
It makes you a serious buyer to sellers
An agent or seller weighing up two similar offers will favour the buyer whose finance is sorted. Pre-approval signals that you are genuine and ready, which can be the difference between your offer being accepted or passed over.
Auctions need it
This one is critical. When you buy at auction, there is no cooling-off period and no finance clause. If your bid wins, you are contractually committed. You should never bid at auction without unconditional finance sorted or at the very least solid pre-approval and a clear path to formal approval. Getting this wrong can be financially disastrous.
What lenders check for pre-approval
To assess your pre-approval, a lender looks at the same core things they will examine for the full loan, just at a slightly higher level:
- Income and employment: how much you earn and how stable it is. Permanent salaried income is the most straightforward to assess.
- Deposit and genuine savings: how much you have saved, and evidence you have genuinely saved it. Lenders often want to see at least 5 per cent of the price saved steadily over about three months.
- Existing debts and commitments: credit cards, car loans, personal loans and buy-now-pay-later all reduce how much you can borrow.
- Living expenses: your regular spending, to check you can comfortably manage repayments.
- Credit history: your track record of managing credit. A clean history helps.
Two rules lenders apply in 2026
When working out your maximum, lenders assess whether you could still afford repayments if rates rose. APRA requires them to add a serviceability buffer of 3 per cent on top of the actual rate. Separately, from February 2026, APRA limits how much lending banks can do at six times your income or more. If you are borrowing close to your maximum, these two rules are often what sets your ceiling, which is another reason to get assessed early.
Not all pre-approvals are equal
There is an important difference between two types of pre-approval, and it catches people out. A system-generated pre-approval is produced automatically by a lender’s computer with little human checking. It is quick, but it is weak, because a credit assessor has not actually reviewed your file. A fully assessed pre-approval, where a real credit officer has verified your documents, is far more reliable and much less likely to fall over later.
When we arrange pre-approval for clients, we push for the fully assessed kind wherever possible, so that when you find your home, the path to formal approval is as smooth and certain as it can be.
How long does pre-approval last?
Pre-approval is usually valid for around 90 days, though some lenders issue it for 60 days and a few extend to 120. If it expires before you buy, it can generally be renewed, but the lender will want updated payslips and bank statements to confirm nothing has changed. Because of this, it makes sense to get pre-approved when you are genuinely ready to start looking, rather than months in advance.
Pre-approval is the step that turns you from a browser into a buyer. It tells you your budget, lets you move quickly and bid with confidence, and shows sellers you are serious. Just remember it is conditional, not final, and that a fully assessed pre-approval is worth far more than a quick automated one.
