Where every figure above comes from, how current it is and what it can't tell you.
- How the estimate is made
- The estimate for 23 Coval Avenue is modelled from its 106 m² EPC floor area, its 3 recorded sales and recent sales of comparable homes in CM1 1TF. 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 23 Coval Avenue. Sales normally appear two to three months after completion, so the most recent ones take time to show up anywhere.
- Reading the EPC

- Planning applications are collected from local authority registers through PlanIt. 2 applications are matched to 23 Coval Avenue. Councils sometimes file applications under a different address format, and applications on neighbouring land aren't listed here; the report covers both.
- Area figures
- Crime is police-recorded street-level data over the last 18 months, which places each incident at an approximate point.
