Market Overview: SL1
Prices in SL1 span a notably wide range, from £100k at the lower end to £595k at the top of the 16-sale sample — a signal that the local housing stock is mixed rather than homogeneous.
Flats were the most common transaction type, representing 62% of sales, while semi-detached houses accounted for 25%. A flats-heavy composition like this usually points to a city-centre or regeneration postcode where high-density apartment blocks have replaced or supplemented older stock.
For buyers and sellers in SL1 1AA, 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 6.0%, based on ONS regional rents.
