Market Overview: KT21
The median sale price in KT21 is £640k, drawn from 15 residential transactions in the last twelve months. Individual sales ranged from £300k to £1.27m, which is a normal spread for a postcode of this size.

The KT21 1AA 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 2.2%, based on ONS regional rents.
