7 First Home Buyer Mistakes That Cost Australians Thousands

Buying your first home is one of the biggest financial decisions you'll ever make — and the mistakes first home buyers make can cost them tens of thousands of dollars. Here are the seven most common and costly errors, and exactly how to avoid them.

1. Not Getting Pre-Approval First

Searching for a property without knowing your borrowing capacity is one of the most common mistakes. Without a pre-approval, you don't know your budget, you can't move quickly when you find the right property, and you risk wasting months falling in love with homes you can't actually buy.

Get a formal pre-approval from your bank or mortgage broker before you start inspecting properties. This gives you a clear budget and makes you a credible buyer when you find the right property.

2. Not Knowing Which Grants They Qualify For

In 2026, first home buyers can access the First Home Guarantee (5% deposit, no LMI), the First Home Owner Grant (up to $30,000 in QLD), stamp duty exemptions, and the First Home Super Saver Scheme. Many buyers miss one or more of these schemes — sometimes costing themselves $20,000 to $50,000 in benefits they were entitled to.

3. Buying Emotionally, Not Strategically

First home buyers often fall in love with a property and then make poor financial decisions to "win" it — paying over market value, skipping building inspections, or choosing a property with significant problems. Buying a home is emotional; paying for it doesn't have to be. Keep the numbers objective.

4. Skipping the Building and Pest Inspection

A building and pest inspection costs $400–$600 and can save you from buying a property with termite damage, structural defects, or moisture issues that cost tens of thousands to repair. Never skip this step, regardless of what the selling agent tells you about the property's condition.

5. Underestimating the True Cost of Buying

The purchase price is just the beginning. First home buyers regularly underestimate the full cost of purchase, which includes stamp duty (unless exempted), legal fees ($1,500–$2,500), building inspection, loan application fees, moving costs, and initial maintenance. Budget an additional 3–5% of the purchase price for these costs.

6. Choosing the Wrong Location

Location is the single most important driver of long-term property value. Buying a great house in the wrong location consistently underperforms buying a modest house in the right location. Research infrastructure investment, school catchments, employment access, and population growth trends in the suburbs you're considering — not just the price and features of the property itself.

7. Going It Alone Instead of Getting Expert Help

The selling agent works for the vendor. That's their legal obligation. Yet most first home buyers negotiate against a professional agent without any representation of their own. A buyer's agent works exclusively for you — helping you find the right property, assessing its true market value, and negotiating the best possible price. For most buyers, the cost of a buyer's agent is recovered many times over in a better purchase price alone.
