I watch these happen every campaign, from good, careful people. None of them are mistakes of intelligence. They are mistakes of sequence — doing things in the wrong order, or leaving something until the moment when it is too late to do anything about it.
Falling in love before doing the maths. Emotion is fine; emotion without a budget is dangerous. Know your absolute ceiling before you walk in.
Write the ceiling down before you go, and write down why it is that number — the repayment you can live with, not the loan a bank will approve. The two are different, and the gap between them is where people get into trouble. A pre-approval is the bank's view of your maximum risk, not a recommendation. Then tell someone else the number. It is remarkably hard to quietly move a figure you have said out loud to your partner.
Skipping the building report to "save" $700. A building report on a $1.2m home is the cheapest insurance policy you will ever buy.
The version of this that costs even more is getting the report and then not reading it properly. Inspectors write carefully, and the sentence that matters is often mid-paragraph and undramatic — moisture readings elevated in one corner, or a recommendation for further specialist investigation. If a report recommends a further inspection, that is not a formality to be waived because you are in a hurry. Ring the inspector and ask them directly what worries them most. They will tell you, and it is usually not the item you were focused on.
Buying at auction changes the maths here, because auction purchases are unconditional. Every check you would normally make a condition — building report, LIM, finance, insurance — has to be done and paid for before the day, on a property you may not win. That cost is real, and it is the reason many buyers get outbid three times before they succeed. Budget for it rather than being surprised by it.
Negotiating themselves out of a deal over a few thousand dollars. If the home is right, the gap between $1.18m and $1.20m disappears the day you move in.
The useful reframe: work out what the difference costs you per week over the life of the loan. It is usually a small number, and setting it against the years you will live there makes the decision obvious. That does not mean overpaying — it means not losing the right house over an amount that will be invisible within a year.
Trusting verbal promises. Anything that matters belongs in writing in the contract.
This applies most often to chattels and to work the vendor has said they will complete before settlement. The dishwasher, the heat pump, the garden shed, the promise to fix the fence — if it is not listed in the agreement, it is not yours and it is not happening. And be specific: "curtains" is weaker than naming the rooms.
A related one is relying on what you were told rather than what you can verify. An agent has obligations to be accurate, but the person carrying the risk on the LIM, the title, the consents and the insurance position is you. If something matters to your decision — a consented extension, a fireplace, a flood history — check it in the documents rather than in conversation.
Waiting for the "perfect" market. The perfect market only exists in hindsight. The right home for you appears when it appears — be ready.
Being ready is the actionable half of that sentence, and it is a checklist rather than a feeling: finance arranged with a number you have confirmed this month, a solicitor briefed and expecting your call, an inspector you have already spoken to, and a clear view of which suburbs genuinely work for you. Buyers who have done those four things can move on a Tuesday. Buyers who have not spend the week getting organised while somebody else signs.
The last mistake is the quietest one: buying a house you like and a location you do not. You can renovate a kitchen. You cannot move the house closer to the school, the motorway on-ramp, or the sun. Be relentlessly fussy about what cannot be changed, and much more relaxed about what can.
