14 HARKNESS ROAD 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 four 14 HARKNESS ROAD sales between June 2004 and August 2022 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 2018 sale was for 32% below the HPI. So the extrapolation line tracks at 32% below the HPI over time, until the August 2022 sale, where it rises to 30% below the HPI. The line then continues to track at 30% below the HPI.
