20 THE ISLAND Price Paid vs. HPI Average

The below graph shows the average detached house price in the Buckinghamshire local authority area over time, sourced from the HPI. The three 20 THE ISLAND sales between January 2001 and August 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 June 2020 sale was for 54% below the HPI. So the extrapolation line tracks at 54% below the HPI over time, until the August 2024 sale, where it falls to 55% below the HPI. The line then continues to track at 55% below the HPI.
