21 NORTHFIELD GREEN 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 NORTHFIELD GREEN sales between February 1995 and December 2015 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 July 1998 sale was for 74% above the HPI. So the extrapolation line tracks at 74% above the HPI over time, until the December 2015 sale, where it falls to 56% above the HPI. The line then continues to track at 56% above the HPI.
