10 CASTELL Y FAN Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the Caerphilly local authority area over time, sourced from the HPI. The two 10 CASTELL Y FAN sales from June 2002 and December 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 23% above the HPI. So the extrapolation line tracks at 23% above the HPI over time, until the December 2006 sale, where it falls to 20% above the HPI. The line then continues to track at 20% above the HPI.

What might 10 CASTELL Y FAN be worth now?
