- The estimate for 20 Cowgill Close is modelled from its 80 m² EPC floor area, its 3 recorded sales and recent sales of comparable homes in NN3 8PB. 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. 3 sales are recorded for 20 Cowgill Close. Sales normally appear two to three months after completion, so the most recent ones take time to show up anywhere.
