15 CRYSTAL AVENUE 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 15 CRYSTAL AVENUE sales from June 2012 and November 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 June 2012 sale was for 29% below the HPI. So the extrapolation line tracks at 29% below the HPI over time, until the November 2015 sale, where it rises to 12% below the HPI. The line then continues to track at 12% below the HPI.
