20 COLDHARBOUR LANE Price Paid vs. HPI Average

The below graph shows the average detached house price in the Tonbridge and Malling local authority area over time, sourced from the HPI. The three 20 COLDHARBOUR LANE sales between January 1997 and July 2024 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 March 2011 sale was for 119% above the HPI. So the extrapolation line tracks at 119% above the HPI over time, until the July 2024 sale, where it falls to 87% above the HPI.
