21 STEWART DRIVE 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 two 21 STEWART DRIVE sales from March 2001 and December 2009 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 2001 sale was for 2% above the HPI. So the extrapolation line tracks at 2% above the HPI over time, until the December 2009 sale, where it falls to 1% above the HPI. The line then continues to track at 1% above the HPI.
