- The estimate for 11 Heath Lawn is modelled from its 122 m² EPC floor area, its 4 recorded sales and recent sales of comparable homes in HP10 9EX. 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 11 Heath Lawn. Sales normally appear two to three months after completion, so the most recent ones take time to show up anywhere.
- Reading the EPC

- Area figures
- Crime is police-recorded street-level data over the last 17 months, which places each incident at an approximate point.
