13 GARTH 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 13 GARTH ISAF sales from March 2020 and July 2024 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 2020 sale was for 42% above the HPI. So the extrapolation line tracks at 42% above the HPI over time, until the July 2024 sale, where it rises to 45% above the HPI. The line then continues to track at 45% above the HPI.
