Castle Street is a street almost entirely of flats. The median sale price is £90,000, about 54% below the typical NN1 sale. Too few recent sales to read a street-level trend, but across NN1 prices have held broadly level over the last few years. HM Land Registry records 15 sales across 10 homes since 2002 — homes here come up rarely.
