The suburbs where the numbers line up for buyers, investors and developers — built from 120 Adelaide suburbs' sale records (3Q 2026), rental bond medians (1 January - 31 March 2026), and GoSiteHunt's registered developer buy-box demand. Every input is a government record or a live platform signal — no survey, no opinion.

Each suburb needs at least 12 house sales in the quarter and a rental bond median to qualify. The score weighs gross rental yield (weekly bond median × 52 ÷ sale median), year-on-year median movement (ignored when a small sample makes it unreliable), the number of active developer buy-boxes on GoSiteHunt whose criteria the suburb satisfies, and sales depth. It is a screening index of public data — a place to start looking, not advice on what to buy.
Data snapshots — median, rents by bedroom, indicative yield — for the leaders: Willaston · Salisbury Heights · Happy Valley · Old Reynella · Blakeview · Modbury · Morphett Vale · Davoren Park · Elizabeth East · Riverlea Park.

The index is suburb-level. For a single property — zoning, what could be built, what a developer could pay — run a GoSiteHunt site check or start with the Deal Killer Checklist (1 credit; new accounts get 20 free credits for 30 days).
