18 THE SPIERT 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 two 18 THE SPIERT sales from October 1997 and April 2019 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 1997 sale was for 15% above the HPI. So the extrapolation line tracks at 15% above the HPI over time, until the April 2019 sale, where it falls to 26% below the HPI. The line then continues to track at 26% below the HPI.
