15 BANK MILL Price Paid vs. HPI Average

The below graph shows the average detached house price in the Dacorum local authority area over time, sourced from the HPI. The two 15 BANK MILL sales from November 2013 and March 2014 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 November 2013 sale was for 33% below the HPI. So the extrapolation line tracks at 33% below the HPI over time, until the March 2014 sale, where it falls to 36% below the HPI. The line then continues to track at 36% below the HPI.

What might 15 BANK MILL be worth now?
