143 HEOL ISAF 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 143 HEOL ISAF sales from March 2004 and November 2018 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 March 2004 sale was for 47% above the HPI. So the extrapolation line tracks at 47% above the HPI over time, until the November 2018 sale, where it rises to 120% above the HPI. The line then continues to track at 120% above the HPI.
