Market Overview: SE21
Turnover in SE21 has been high, with 94 residential sales logged by HM Land Registry in the last twelve months — enough volume that the median figure is reasonably representative.
Flats were the most common transaction type, representing 46% of sales, while terraced houses accounted for 28% and semi-detached houses accounted for 22%.
The twelve-month trend is softer than it was: the median in the second half of the window was 31.7% below the first-half median. Monthly volume was fairly consistent, giving the trend line a reliable shape.
For buyers and sellers in SE21 7AA, 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 3.1%, based on ONS regional rents.
