22A BLACKMILE LANE 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 22A BLACKMILE LANE sales from April 2014 and September 2021 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 April 2014 sale was for 10% above the HPI. So the extrapolation line tracks at 10% above the HPI over time, until the September 2021 sale, where it rises to 17% above the HPI. The line then continues to track at 17% above the HPI.
