21 MILL ROAD Price Paid vs. HPI Average

The below graph shows the average detached house price in the North Northamptonshire local authority area over time, sourced from the HPI. The two 21 MILL ROAD sales from September 1996 and April 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 September 1996 sale was for 8% above the HPI. So the extrapolation line tracks at 8% above the HPI over time, until the April 2018 sale, where it falls to 29% below the HPI. The line then continues to track at 29% below the HPI.
