Market Overview: SE21
The median sale price in SE21 is £428k, drawn from 24 residential transactions in the last twelve months. Individual sales ranged from £265k to £1.92m, which is a normal spread for a postcode of this size.
The local market is dominated by flats, which made up 75% of all sales in the sample, while terraced houses accounted for 17%. That flats-heavy composition is typical of central and inner-London postcodes where purpose-built blocks and converted period buildings dominate.
The SE21 7AA 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 5.1%, based on ONS regional rents.
