Source & freshness

QuickProperty mixes release files, Census baselines, and matched local services on this page. Read the status panel before treating every metric as equally fresh.

PRICE POSTURE
Prices come from release-based suburb series.

Release-based suburb price series, not a live market feed

RENT POSTURE
Rent is using a state market dataset when available.

Use current rent as a starting signal, not as a fixed underwriting truth.

SERVICE POSTURE
Service coverage is matched locally, not inferred nationally.

Schools, transport, and hospitals are useful as presence signals, but they still have different source cadences.
