40 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 40 PLAS Y MYNACH sales from August 2001 and January 2019 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 2001 sale was for 51% above the HPI. So the extrapolation line tracks at 51% above the HPI over time, until the January 2019 sale, where it falls to 4% above the HPI.
