How the estimate is made
The estimate for 12 Mortimer Road is modelled from its 144 m² EPC floor area, its 4 recorded sales and recent sales of comparable homes in CF11 9JZ.

Where sold prices come from
Sold prices are HM Land Registry Price Paid Data, which covers residential sales in England and Wales since 1995. 4 sales are recorded for 12 Mortimer Road. Sales normally appear two to three months after completion, so the most recent ones take time to show up anywhere.
