The below graph shows the average detached house price in the West Northamptonshire local authority area over time, sourced from the HPI. The three 15 TANFIELD LANE sales between November 2002 and November 2024 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 December 2015 sale was for 10% above the HPI. So the extrapolation line tracks at 10% above the HPI over time, until the November 2024 sale, where it falls to 8% above the HPI. The line then continues to track at 8% above the HPI.
