PropertyEye tracks live listings in Sydney and Brisbane today — Adelaide pages are built from published auction results (2021–2026), our price model and weekly clearance data. Live Adelaide tracking is on the roadmap.
Price model — what the model says a typical home here achieves at auction
| Configuration | Model estimate | Range | Comparable sales |
|---|---|---|---|
| 3-bed house | $1.05M | $940k–$1.17M | 31 |
| 4-bed house | $1.18M | $1.05M–$1.31M | 31 |
| 5-bed house | $1.26M | $907k–$1.69M | 31 |
Modelled from 146,492 Australian auction sales (2021–2026). Adelaide cells run on the base model (suburb prior + configuration + time) without the Sydney-only land/school/transport features — ranges are honest about the wider uncertainty. Estimates from comparable auction results — not valuations or financial advice.
