How the estimate is made
The estimate for 37 Granogwen Road is modelled from its 58 m² EPC floor area, its 1 recorded sale and recent sales of comparable homes in SA1 6UN. It is an automated estimate, not a survey or mortgage valuation: condition, layout and improvements that aren't on record can move the real figure either way.
Where sold prices come from
Sold prices are HM Land Registry Price Paid Data, which covers residential sales in England and Wales since 1995. 1 sale is recorded for 37 Granogwen Road. Sales normally appear two to three months after completion, so the most recent ones take time to show up anywhere.
