Market Overview: SM1
Activity in SM1 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 £720k, which is a normal spread for a postcode of this size.
No single property type dominates — flats led with 38% but the mix is diverse, while terraced houses accounted for 27% and semi-detached houses accounted for 30%.
The SM1 1AH 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 3.4%, based on ONS regional rents.
