The below graph shows the average semi-detached house price in the Bexley local authority area over time, sourced from the HPI. The two 40 WALTON ROAD sales from February 2014 and December 2015 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 February 2014 sale was for 60% above the HPI. So the extrapolation line tracks at 60% above the HPI over time, until the December 2015 sale, where it rises to 81% above the HPI. The line then continues to track at 81% above the HPI.

40 WALTON ROAD might now be worth an estimated £955,403.
This is based on house price inflation of 43%, between December 2015 and April 2026, for semi-detached houses, in the Bexley local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).
The 43% inflationary increase is applied to the most recent sale price for 40 WALTON ROAD of £668,000 on 11th December 2015. For the value to have increased from £668,000 to £955,403 over the eleven years and eight months to April 2026, the following assumptions must hold true:
