How to Research a Suburb
Understanding the Numbers
Median house price represents the middle sale in a period — not the average. Rental yield is annual rent divided by property value. Vacancy rate below 3% indicates strong tenant demand. Annual growth shows 12-month price change — not a guarantee of future performance.
What to Research Before Buying
Check council zoning and DA restrictions, flood and bushfire overlays on state planning portals, infrastructure pipeline (rail, roads, schools), employer concentration (single-industry suburbs carry higher risk), and auction clearance rates (above 70% signals a seller's market).
Due Diligence Checklist
- ☐ Building and pest inspection
- ☐ Strata report (if applicable)
- ☐ Contract review by conveyancer
- ☐ Comparable sales in last 90 days
- ☐ Rental vacancy rate
- ☐ Council rates and water rates
- ☐ Body corporate fees (if applicable)
