Market Overview: SL4
Turnover in SL4 has been high, with 289 residential sales logged by HM Land Registry in the last twelve months — enough volume that the median figure is reasonably representative. Individual sales ranged from £122k to £3.10m, which is a normal spread for a postcode of this size.
No single property type dominates — terraced houses led with 35% but the mix is diverse, while semi-detached houses accounted for 24% and flats accounted for 25%.
The twelve-month trend is softer than it was: the median in the second half of the window was 7.6% below the first-half median. Monthly volume was fairly consistent, giving the trend line a reliable shape.
Liquidity in SL4 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 2.8%, based on ONS regional rents.
