What to check

Sources & freshness
Verify-heavy evidence

Much of Seaforth rests on evidence that should be verified before a decision.

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.

Direct state price coverage is used where present; missing house or unit anchors fall back to annual ABS SA2 matches

RENT POSTURE
Rent is falling back to Census, not a market feed.

This gives you directional coverage, but it is weaker than a current rent release.

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.
