21 BLACKWELL HILL Price Paid vs. HPI Average

The below graph shows the average detached house price in the West Northamptonshire local authority area over time, sourced from the HPI. The three 21 BLACKWELL HILL sales between March 2002 and June 2012 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 March 2004 sale was for 39% below the HPI. So the extrapolation line tracks at 39% below the HPI over time, until the June 2012 sale, where it falls to 45% below the HPI. The line then continues to track at 45% below the HPI.
