12 CLOS Y MYNYDD 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 12 CLOS Y MYNYDD sales from September 2007 and February 2011 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 2007 sale was for 86% above the HPI. So the extrapolation line tracks at 86% above the HPI over time, until the February 2011 sale, where it falls to 83% above the HPI. The line then continues to track at 83% above the HPI.

What might 12 CLOS Y MYNYDD be worth now?
