Treat the rent field as missing until a market or plausible Census rent value is linked.
Schools, transport, and hospitals are useful as presence signals, but they still have different source cadences.
This page stays indexable because Costello is a real locality with enough context to be directionally useful. The tradeoff is that coverage is lighter than a stronger suburb profile, so the read should stay cautious.
Small-population localities can still be worth checking, but rankings, comparisons, and broad suburb assumptions become noisier faster.
Coverage is thinner on school matches, hospital coverage, transport stops, and crime coverage; lean less on this one page and confirm those gaps elsewhere.
Check nearby suburbs, the state hub, and rankings for firmer comparables before making this a shortlist decision.
