The model measures a district's location by its median price per m² over the previous twelve months, in standard deviations across London's postcode districts. RM6 sits 1.02 standard deviations below the average district.

Prices are HM Land Registry price paid data for homes sold in RM6, each matched by address to its MHCLG energy performance certificate for the floor area. Price per m² is the price paid divided by that floor area; medians are taken over the twelve months to the month shown, and districts, their postcode area and London are always compared over the same twelve months. Sales without a matched certificate, and non-residential and "other" sales, are not counted.
