Marion house prices, 2026.

The median house price across the Marion region is $1,215,375. That figure is the median of 32 suburb medians, each drawn from government sales records, rather than an average, so a handful of waterfront or acreage suburbs cannot drag it up. The median unit price is $274,320. The median house rent is $318 a week.

Over the past twelve months the typical Marion suburb rose by 13.1% in median house price. The spread between suburbs is wide: South Brighton recorded +22.5%, the fastest of the established suburbs with plausible growth data. A change beyond 25% in a year, the mark of a handful of sales, is left out of the growth figures.

Among established suburbs, the most affordable is Reynella East at $805,000 and the dearest is Somerton Park at $2,420,000, a 3.0-times gap across the one region. The suburbs with the most recorded house sales in the latest period are Reynella (33), Warradale (31), Edwardstown (23); the table below lists the twenty busiest with their medians.
