17 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 three 17 HEOL ISAF sales between August 1996 and January 2023 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 May 1999 sale was for 99% above the HPI. So the extrapolation line tracks at 99% above the HPI over time, until the January 2023 sale, where it rises to 127% above the HPI. The line then continues to track at 127% above the HPI.
