Market Overview: SO45
With 257 recorded transactions in twelve months, SO45 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 £30k to £1.50m, which is a normal spread for a postcode of this size.
No single property type dominates — detached houses led with 39% but the mix is diverse, while semi-detached houses accounted for 28% and terraced houses accounted for 21%.
The twelve-month trend is upward: comparing the first half of the window with the second, the median shifted by roughly +9.1%. Monthly volume was fairly consistent, giving the trend line a reliable shape.
Liquidity in SO45 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 4.4%, based on ONS regional rents.
