Valuation method in detail
How the estimate is made
The estimate for 17 Golwg Y Garn is modelled from its 71 m² EPC floor area, its 4 recorded sales and recent sales of comparable homes in SA4 9DE. 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. 4 sales are recorded for 17 Golwg Y Garn. Sales normally appear two to three months after completion, so the most recent ones take time to show up anywhere.
