144 SYWELL ROAD 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 144 SYWELL ROAD sales from November 2003 and October 2007 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 November 2003 sale was for 2% below the HPI. So the extrapolation line tracks at 2% below the HPI over time, until the October 2007 sale, where it rises to 49% above the HPI. The line then continues to track at 49% above the HPI.
