Market Overview: SO21
With 110 recorded transactions in twelve months, SO21 is one of the more liquid postcodes in the sample — individual outliers have less pull on the median figure than they would elsewhere. Individual sales ranged from £141k to £8.75m, which is a normal spread for a postcode of this size.
No single property type dominates — detached houses led with 40% but the mix is diverse, while terraced houses accounted for 22% and semi-detached houses accounted for 26%.
The twelve-month trend is softer than it was: the median in the second half of the window was 30.8% below the first-half median. Monthly volume was fairly consistent, giving the trend line a reliable shape.
Liquidity in SO21 1AA is healthy: the high sale count makes it easier to benchmark a specific property against genuinely recent comparables rather than extrapolating from older deals. On the rental side, the estimated gross yield on a median-priced property here is around 2.7%, based on ONS regional rents.
