FLAT Price Paid vs. HPI Average

The below graph shows the average detached house price in the Caerphilly local authority area over time, sourced from the HPI. The two FLAT sales from October 2001 and November 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 October 2001 sale was for 53% below the HPI. So the extrapolation line tracks at 53% below the HPI over time, until the November 2023 sale, where it falls to 60% below the HPI. The line then continues to track at 60% below the HPI.
