CASTLE KEEP 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 CASTLE KEEP sales between April 1995 and June 2016 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 July 2012 sale was for 92% above the HPI. So the extrapolation line tracks at 92% above the HPI over time, until the June 2016 sale, where it falls to 41% above the HPI. The line then continues to track at 41% above the HPI.
