28 TROON AVENUE Price Paid vs. HPI Average

The below graph shows the average detached house price in the Darlington local authority area over time, sourced from the HPI. The two 28 TROON AVENUE sales from September 1996 and July 2015 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 September 1996 sale was for 31% below the HPI. So the extrapolation line tracks at 31% below the HPI over time, until the July 2015 sale, where it falls to 45% below the HPI. The line then continues to track at 45% below the HPI.

What might 28 TROON AVENUE be worth now?
