17 CASTLEMAIN AVENUE Price Paid vs. HPI Average

The below graph shows the average detached house price in the Bournemouth Christchurch and Poole local authority area over time, sourced from the HPI. The three 17 CASTLEMAIN AVENUE sales between October 2000 and August 2006 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 June 2002 sale was for 12% above the HPI. So the extrapolation line tracks at 12% above the HPI over time, until the August 2006 sale, where it falls to 9% above the HPI. The line then continues to track at 9% above the HPI.

What might 17 CASTLEMAIN AVENUE be worth now?
