How do I research a suburb before buying?
Cover four lanes: market data (price, rent, vacancy), supply pipeline (DAs, zoning, build approvals), demographic momentum (population growth, household formation), and risk overlay (flood, bushfire, infrastructure dependency). Always tie each metric to a primary source.
Start with the basics: median house + unit price (last 12 months sales), median rent (current listings + bond data), vacancy rate, days on market. ABS data for census-derived metrics + state land records for sale prices + NSW Fair Trading bond data for rents. Don't trust portal-aggregated 'data points', go to the source.
Layer the supply pipeline: pull DAs (development applications) from the relevant council's planning portal. A suburb with 50+ approved DAs in the next 24 months is going to absorb supply that affects yield + capital growth. Most councils publish this monthly; some have RSS feeds we ingest.
Demographic momentum: population growth rate (ABS QuickStats), age + income distribution shifts (5-year deltas in ABS census tables), household formation rate (proxy for rental demand depth). Suburbs with rising young-professional household formation tend to sustain rent growth.
Risk overlays: flood (NSW SES, VIC EPA flood map, etc.), bushfire (state RFS bushfire-prone-land mapping), coastal erosion (state DPE), transit dependency (one-train-line risk, e.g. Wollongong's South Coast Line). Risk overlays affect insurance cost, resale liquidity, and downside in worst-case scenarios.
