Bond-lodgement medians from the SA Rental Bond Data — Private Rental Report, data.sa.gov.au (CC-BY, SA Housing Trust), 1 January - 31 March 2026. "Low sample" = the count is masked or small at source; treat those medians with care.
Gross yield around 3.4% is thin — projects in St Marys lean on end values, not rent. Sell-down schemes (subdivide-and-sell, build-and-sell) fit the profile better than holds financed on rental income. The +9% year-on-year move comes off only 8 sales — too thin a sample to trust as momentum, so weight it accordingly. All of the above is area-level screening, not advice: a specific parcel lives or dies on zoning, overlays, frontage, and the end value of what it can actually carry.
This page is suburb-level screening. For one property — zoning, what could be built, what a developer could pay — run a GoSiteHunt site check, screen it with the free Deal Killer Checklist, or see how many units fit on a block.

Suburb-level data. Rents are quarterly bond-lodgement medians from the SA Private Rental Report; sale medians are the data.sa.gov.au metropolitan median house sales series (country suburbs may show rents only). Indicative gross yield = headline weekly bond median × 52 ÷ sale median — a screening ratio, not a valuation input.

Area medians can move sharply between periods, especially on thin samples. © Madison Jade Pty Ltd.
