6 THE KNOLL Price Paid vs. HPI Average

The below graph shows the average detached house price in the North Northamptonshire local authority area over time, sourced from the HPI. The three 6 THE KNOLL sales between October 2003 and August 2010 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 September 2009 sale was for 640% above the HPI. So the extrapolation line tracks at 640% above the HPI over time, until the August 2010 sale, where it falls to 501% above the HPI. The line then continues to track at 501% above the HPI.
