23 WEST STREET 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 23 WEST STREET sales from March 2010 and June 2018 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 2010 sale was for 81% above the HPI. So the extrapolation line tracks at 81% above the HPI over time, until the June 2018 sale, where it falls to 33% above the HPI. The line then continues to track at 33% above the HPI.
