21 THE MOUNT Price Paid vs. HPI Average

The below graph shows the average detached house price in the Three Rivers local authority area over time, sourced from the HPI. The three 21 THE MOUNT sales between April 1996 and March 2015 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 February 2004 sale was for 47% above the HPI. So the extrapolation line tracks at 47% above the HPI over time, until the March 2015 sale, where it rises to 51% above the HPI. The line then continues to track at 51% above the HPI.
