The below graph shows the average detached house price in the West Northamptonshire local authority area over time, sourced from the HPI. The three 20 CASTLE MOUNT sales between September 1997 and April 2013 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 1999 sale was for 49% below the HPI. So the extrapolation line tracks at 49% below the HPI over time, until the April 2013 sale, which was also at 49% below the HPI.
