Market Overview: SO31
With 444 recorded transactions in twelve months, SO31 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 £53k to £8.33m, which is a normal spread for a postcode of this size.
No single property type dominates — detached houses led with 37% but the mix is diverse, while terraced houses accounted for 20% and semi-detached houses accounted for 25%.
Prices have been essentially flat across the twelve-month window, moving by under 4% in either direction. Monthly volume was fairly consistent, giving the trend line a reliable shape.
Liquidity in SO31 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 4.0%, based on ONS regional rents.
