Market Overview: SO20
Activity in SO20 over the last twelve months ran to 37 residential sales, giving a workable sample size for median-level analysis. Individual sales ranged from £205k to £9.50m, which is a normal spread for a postcode of this size.
Detached houses were the most common transaction type, representing 54% of sales, while semi-detached houses accounted for 30%.
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.
The SO20 6AA dataset is a reasonable baseline, but decisions at the individual-property level should still lean on matched comparables rather than the area median alone. On the rental side, the estimated gross yield on a median-priced property here is around 2.3%, based on ONS regional rents.
