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
3.8% of SG1 sales were new builds and 20.9% were leasehold. Most sales here were freehold, which usually means houses.
