12 WESTMINSTER DRIVE 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 12 WESTMINSTER DRIVE sales from January 2007 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 January 2007 sale was for 25% below the HPI. So the extrapolation line tracks at 25% below the HPI over time, until the August 2024 sale, where it falls to 38% below the HPI. The line then continues to track at 38% below the HPI.
