Market Overview: SO31
Across the last twelve months, 7 residential sales in SO31 produced a median price of £410k. Individual sales ranged from £260k to £915k, which is a normal spread for a postcode of this size.
The local market is dominated by detached houses, which made up 86% of all sales in the sample. Detached-house dominance points to lower-density suburban or village character, with meaningfully larger lot sizes than the UK average.
The SO31 1AA 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 3.5%, based on ONS regional rents.
