A part-year and a small mix shift (say, more flats sold this year) can move a median without any change in what homes are worth, so treat year-to-year differences with care.

New builds and leasehold

0% of SE21 sales were new builds and 53.2% were leasehold. A high leasehold share usually means lots of flats: check the lease length, ground rent and service charge before you offer.

About these figures. Every standard (category A) residential sale HM Land Registry recorded in SE21 from January 2025 to September 2026. Repossessions, buy-to-let portfolio sales and other non-standard transfers are excluded. A district median is not a valuation of any home. How Boroughly sources data.
