411 BLACKFEN ROAD Price Paid vs. HPI Average

The below graph shows the average detached house price in the Bexley local authority area over time, sourced from the HPI. The two 411 BLACKFEN ROAD sales from July 2013 and July 2016 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 July 2013 sale was for 23% below the HPI. So the extrapolation line tracks at 23% below the HPI over time, until the July 2016 sale, where it rises to 18% below the HPI. The line then continues to track at 18% below the HPI.

What might 411 BLACKFEN ROAD be worth now?
