Common first-home buyer mistakes — and how to avoid them

Buying a first home is a high-stakes, low-repetition task. You only do it once or twice in a lifetime. The mistakes we see most often aren't catastrophic on their own — but they compound and cost real money. Here's the short list.

1. Getting pre-approved at the wrong lender

A pre-approval is only as good as the lender's appetite for your scenario. Many first-home buyers grab the first pre-approval they get (often from their everyday bank) and assume it's the strongest offer. It usually isn't.

The fix: get an assessment of which 3–4 lenders are actually competitive for your profile, then pre-approve with the best match. Lender choice can shift your borrowing capacity by $50k–$100k.

2. Treating credit card limits as harmless

Lenders assess your credit limits, not your balances. A $20,000 card limit you "never use" can chop $80,000–$100,000 off your borrowing capacity. Many first-home buyers don't realise this until the application stalls.

The fix: close or reduce limits before you apply, not during. Credit checks during an active application get messy.

3. Underestimating total acquisition cost

The deposit is the headline number; it isn't the full number. Stamp duty (or its absence), legal fees, building/pest, lender fees, moving costs, immediate repairs — these add up to $15k–$30k on a typical first purchase.

The fix: model total cash required, then save against that. Aim to have 1–2% of the purchase price in buffer at settlement, not zero.

4. Buying just above a concession threshold

NSW, VIC, QLD all have first-home buyer stamp duty concessions tied to specific price brackets. Buy at $801k in some states and you pay full duty on a property where $800k would have given you a partial exemption. The cost difference can be $10k–$20k for $1k of purchase price.

The fix: know the threshold for your state before you negotiate.

5. Conflating affordability with comfort

The bank's maximum approval is the upper limit of what you can pay, not what you should. Affordability for the lender models a fixed snapshot. Comfort for you models the next 5–7 years — including kids, holidays, career changes, rate rises.

The fix: model repayments at current rate + 2%. If you can still afford holidays at that number, you're buying at the right level.

6. Skipping the building and pest

For a $700 inspection, you can find $50k of issues. Every now and then a first-home buyer skips this to look more competitive at auction. We've never seen that work out well.

These mistakes are common because nobody tells first-home buyers about them in advance. A single planning call with a broker before you start house-hunting covers most of them in one sitting.
