Market Overview: SW1Y
Prices in SW1Y span a notably wide range, from £100k at the lower end to £260.00m at the top of the 13-sale sample — a signal that the local housing stock is mixed rather than homogeneous. The £100k–£260.00m range is unusually wide, so the median understates what a buyer will see at either end of the market.
Flats were the most common transaction type, representing 54% of sales, while other property types accounted for 46%.
For buyers and sellers in SW1Y 4AA, 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 2.2%, based on ONS regional rents.
