9 CLOS CEFN BYCHAN Price Paid vs. HPI Average

The below graph shows the average detached house price in the Cardiff local authority area over time, sourced from the HPI. The two 9 CLOS CEFN BYCHAN sales from August 2008 and June 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 August 2008 sale was for 99% above the HPI. So the extrapolation line tracks at 99% above the HPI over time, until the June 2015 sale, where it falls to 74% above the HPI. The line then continues to track at 74% above the HPI.

What might 9 CLOS CEFN BYCHAN be worth now?
