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
2% of N1 sales were new builds and 80.8% were leasehold. A high leasehold share usually means lots of flats: check the lease length, ground rent and service charge before you offer.
