Sale prices, down to the street
We use the last two years of sales data for each neighbourhood, and the last five years of data for each street, we do that because streets often have far fewer sales. Areas stay on the map if any property type you pick typically sells in your range.
- Price per square foot — shown only where five or more sales can be matched to a floor area.
- Property type — the type that has sold most often on each postcode in the last five years. Where nothing has sold that recently we look to older sales, and failing that to the homes’ energy certificates — and the street’s panel tells you when we have.
- Build era — Period (pre-1930), Interwar (1930–49), Postwar (1950–75), Late 20th century (1976–95) or Modern (1996 on), by each postcode's most common construction era.
A postcode's most common era can't promise any individual house — a Period pick keeps streets dominated by period stock.
