How the estimate is made
The estimate for 20 Y Llwyni is modelled from its 59 m² EPC floor area, its 2 recorded sales and recent sales of comparable homes in SA6 6BL. 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. 2 sales are recorded for 20 Y Llwyni. Sales normally appear two to three months after completion, so the most recent ones take time to show up anywhere.
