15 HEOL PEN Y FAI 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 HEOL PEN Y FAI sales from September 1997 and February 2004 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 1997 sale was for 25% below the HPI. So the extrapolation line tracks at 25% below the HPI over time, until the February 2004 sale, where it rises to 1% above the HPI. The line then continues to track at 1% above the HPI.
