21 COPPERFIELD Price Paid vs. HPI Average

The below graph shows the average detached house price in the County Durham local authority area over time, sourced from the HPI. The two 21 COPPERFIELD sales from March 2006 and August 2012 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 March 2006 sale was for 65% above the HPI. So the extrapolation line tracks at 65% above the HPI over time, until the August 2012 sale, where it rises to 93% above the HPI. The line then continues to track at 93% above the HPI.

What might 21 COPPERFIELD be worth now?
