Market Overview: SO21
With 89 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.
No single property type dominates — detached houses led with 38% but the mix is diverse, while terraced houses accounted for 21% and semi-detached houses accounted for 27%.
The twelve-month trend is softer than it was: the median in the second half of the window was 23.6% below the first-half median. Monthly volume was fairly consistent, giving the trend line a reliable shape.
For buyers and sellers in SO21 1AA, the wide dispersion means averages are a weak guide — comparable sales matched on property type, floor area and condition will produce a far tighter estimate. On the rental side, the estimated gross yield on a median-priced property here is around 2.8%, based on ONS regional rents.
