19 BLACKWELL HILL 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 four 19 BLACKWELL HILL sales between December 1996 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 June 2002 sale was for 42% below the HPI. So the extrapolation line tracks at 42% below the HPI over time, until the June 2018 sale, where it rises to 38% below the HPI.
