21 FURLONG WAY Price Paid vs. HPI Average

The below graph shows the average detached house price in the East Hertfordshire local authority area over time, sourced from the HPI. The two 21 FURLONG WAY sales from October 2008 and August 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 October 2008 sale was for 37% below the HPI. So the extrapolation line tracks at 37% below the HPI over time, until the August 2016 sale, where it rises to 29% below the HPI. The line then continues to track at 29% below the HPI.

What might 21 FURLONG WAY be worth now?
