The below graph shows the average semi-detached house price in the Bromley local authority area over time, sourced from the HPI. The four 40 WALPOLE ROAD sales between October 1996 and December 2002 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 April 2002 sale was for 9% below the HPI. So the extrapolation line tracks at 9% below the HPI over time, until the December 2002 sale, where it rises to 4% below the HPI. The line then continues to track at 4% below the HPI.

40 WALPOLE ROAD might now be worth an estimated £643,755.
This is based on house price inflation of 173.9%, between December 2002 and May 2026, for semi-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).
The 173.9% inflationary increase is applied to the most recent sale price for 40 WALPOLE ROAD of £235,000 on 12th December 2002. For the value to have increased from £235,000 to £643,755 over the 24 years and seven months to May 2026, the following assumptions must hold true:
