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

6.2% of SL9 sales were new builds and 22.8% were leasehold. Most sales here were freehold, which usually means houses.
