Valuation method in detail
How the estimate is made
The estimate for Ground Floor Flat is modelled from its 45 m² EPC floor area, its 2 recorded sales and recent sales of comparable homes in WD17 1PT.

Where sold prices come from
Sold prices are HM Land Registry Price Paid Data, which covers residential sales in England and Wales since 1995. 2 sales are recorded for Ground Floor Flat. Sales normally appear two to three months after completion, so the most recent ones take time to show up anywhere.

Planning records
