Buying in this price range
Properties under $500,000 are typically entry-level — units, apartments, or houses in regional areas and outer suburbs. At this price point, first home buyer concessions and grants have the most impact, potentially eliminating stamp duty entirely in several states. The upfront government costs at this level are a smaller proportion of the purchase price, but still represent a significant cash outlay alongside your deposit.
First Home Buyer relief is strongest here
Most states offer full stamp duty exemption or significant concessions at this price point. NSW exempts purchases under $800,000, VIC under $600,000, QLD under $500,000, and SA under $650,000 (new homes). Always check the specific threshold for your state — small differences in price can mean thousands in savings.
Factor stamp duty into your deposit
Even with concessions, you need cash for transfer and mortgage registration fees, conveyancing, and building inspections. Budget 2-3% of the purchase price for total upfront costs beyond the deposit. On a $400,000 property, that is $8,000-$12,000.
Typical buyers: First home buyers, downsizers, regional buyers, and apartment purchasers in capital cities.
