The below graph shows the average detached house price in the Bexley local authority area over time, sourced from the HPI. The two 379 BLACKFEN ROAD sales from August 2017 and October 2018 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 August 2017 sale was for 37% below the HPI. So the extrapolation line tracks at 37% below the HPI over time, until the October 2018 sale, where it rises to 11% above the HPI.
