100 KYNASTON AVENUE 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 100 KYNASTON AVENUE sales from December 1998 and October 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 December 1998 sale was for 12% below the HPI. So the extrapolation line tracks at 12% below the HPI over time, until the October 2019 sale, where it falls to 32% below the HPI. The line then continues to track at 32% below the HPI.
