Market Overview: SO18
Turnover in SO18 has been high, with 310 residential sales logged by HM Land Registry in the last twelve months — enough volume that the median figure is reasonably representative. Individual sales ranged from £800 to £675k, which is a normal spread for a postcode of this size.
No single property type dominates — semi-detached houses led with 30% but the mix is diverse, while detached houses accounted for 25% and flats accounted for 24%.
Prices have been essentially flat across the twelve-month window, moving by under 5% in either direction. Monthly volume was fairly consistent, giving the trend line a reliable shape.
Liquidity in SO18 1AB 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 5.3%, based on ONS regional rents.
