21 HILLSIDE AVENUE Price Paid vs. HPI Average

The below graph shows the average detached house price in the Test Valley local authority area over time, sourced from the HPI. The three 21 HILLSIDE AVENUE sales between December 2010 and August 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 January 2013 sale was for 23% below the HPI. So the extrapolation line tracks at 23% below the HPI over time, until the August 2014 sale, where it rises to 22% below the HPI. The line then continues to track at 22% below the HPI.

What might 21 HILLSIDE AVENUE be worth now?
