Market Overview: SW1Y
SW1Y saw 625 residential sales complete over the twelve-month window, a busy level of activity that makes the local price benchmarks more reliable than in thinner markets.
The local market is dominated by flats, which made up 80% of all sales in the sample. That flats-heavy composition is typical of central and inner-London postcodes where purpose-built blocks and converted period buildings dominate.
The twelve-month trend is softer than it was: the median in the second half of the window was 20.9% below the first-half median. Monthly volume was fairly consistent, giving the trend line a reliable shape.
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 2.7%, based on ONS regional rents.
