The below graph shows the average detached house price in the Bromley local authority area over time, sourced from the HPI. The two 91 HEATHFIELD ROAD sales from July 2002 and June 2006 have been plotted on the graph. A line has been extrapolated to show what the value of the property might have been over time, following each sale, had it maintained the same margin above or below the HPI (as a percentage). For example, the July 2002 sale was for 88% above the HPI. So the extrapolation line tracks at 88% above the HPI over time, until the June 2006 sale, where it falls to 71% above the HPI. The line then continues to track at 71% above the HPI.

91 HEATHFIELD ROAD might now be worth an estimated £1,859,154.
This is based on house price inflation of 124.7%, between June 2006 and May 2026, for detached houses, in the Bromley local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).
