40 MOUNT SION Price Paid vs. HPI Average

The below graph shows the average detached house price in the Tunbridge Wells local authority area over time, sourced from the HPI. The two 40 MOUNT SION sales from June 2010 and March 2020 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 June 2010 sale was for 12% below the HPI. So the extrapolation line tracks at 12% below the HPI over time, until the March 2020 sale, where it rises to 6% above the HPI. The line then continues to track at 6% above the HPI.
