The below graph shows the average detached house price in the West Northamptonshire local authority area over time, sourced from the HPI. The two 35 WAPPENHAM ROAD sales from June 2001 and May 2004 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 June 2001 sale was for 197% above the HPI. So the extrapolation line tracks at 197% above the HPI over time, until the May 2004 sale, where it falls to 159% above the HPI. The line then continues to track at 159% above the HPI.

35 WAPPENHAM ROAD might now be worth an estimated £1,228,654.
