8 PLAS Y MYNACH 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 8 PLAS Y MYNACH sales from August 2002 and October 2016 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 2002 sale was for 44% below the HPI. So the extrapolation line tracks at 44% below the HPI over time, until the October 2016 sale, where it rises to 26% below the HPI.
