How long does it take to build vs buy?

Buying: typically 30-60 days from contract to settlement. Building: 9-15 months from signing to moving in (including design, approvals, and construction). If you need to move quickly, buying is the clear winner.

What about stamp duty differences?

When building, you pay stamp duty only on the land component. When buying established, you pay stamp duty on the full purchase price. This difference can mean significant savings by building, especially at higher price points. First home buyers building a new home under $650,000 also qualify for a full stamp duty exemption.

Is the $15,000 First Home Owner Grant available if I buy established?

No. The FHOG in South Australia is only available for new homes. If you buy an established property, you miss out on the $15,000 grant. You may still qualify for stamp duty concessions on established homes under certain thresholds, but the savings are significantly less than building new. Since June 2024, the FHOG has no property value cap for new builds.

What hidden costs does building have that buying does not?

Building has several costs that are not always included in the advertised price: site costs (soil, slope, rock removal), landscaping and fencing, window treatments, driveway, letterbox, clothesline, and temporary accommodation while you wait. These can add tens of thousands to the total. Buying established, these things are already done, but you may face renovation costs, older plumbing or wiring, and higher stamp duty.

Is it better to build or buy in Adelaide in 2026?

It depends on your priorities. Building offers a brand new home with full warranties, FHOG eligibility, and stamp duty savings. Buying established gets you into a home faster in a more established location. In Adelaide in 2026, building remains the more affordable path for first home buyers due to the generous grant structure. For families wanting an established suburb with mature schools and amenities, buying may make more sense despite the higher stamp duty.

Cost Comparison (Adelaide 2026)

Common Questions

For entry-level homes, building is often cheaper due to stamp duty savings (you only pay stamp duty on land, not the build). A house and land package can save significant stamp duty compared to buying an equivalent established home. However, factor in landscaping, fencing, and temporary accommodation costs.
