21 KNOLE CLOSE 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 eight 21 KNOLE CLOSE sales between May 1997 and June 2021 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 January 2019 sale was for 52% below the HPI. So the extrapolation line tracks at 52% below the HPI over time, until the June 2021 sale, where it rises to 48% below the HPI. The line then continues to track at 48% below the HPI.
