109 JAIL LANE Price Paid vs. HPI Average

The below graph shows the average detached house price in the Bromley local authority area over time, sourced from the HPI. The three 109 JAIL LANE sales between July 2006 and August 2019 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 October 2007 sale was for 13% below the HPI. So the extrapolation line tracks at 13% below the HPI over time, until the August 2019 sale, where it falls to 29% below the HPI. The line then continues to track at 29% below the HPI.
