- How the estimate is made
- The estimate for 47 49 is modelled from its 32 m² EPC floor area, its 2 recorded sales and recent sales of comparable homes in NN1 1JF. 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 47 49. Sales normally appear two to three months after completion, so the most recent ones take time to show up anywhere.
