When buying established wins
- You need to move in inside 6 months
- The suburb you want has no comparable land
- You value mature trees, established schools and streetscape
- Your career or family cannot cope with a 12 – 18 month build timeline
When building wins
- You have a specific lifestyle need (open-plan, home office, granny flat) an established home cannot solve without a major renovation
- You want the 2026 energy-efficiency + NCC-compliant spec, not a 1990s inclusion list
- You want structural warranty and 90 days of defect fix-up
- Your suburb has active greenfield or brownfield opportunities in your budget
The hidden cost people miss
Established: stamp duty. On a $850k SA established purchase, that’s roughly $43,700 - a tax you never see again. New build on new land often qualifies for the First Home Owner Grant and stamp duty concession. Do the maths on YOUR block, but the stamp duty gap alone often shifts the decision.
