18 CONWAY DRIVE 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 five 18 CONWAY DRIVE sales between March 2001 and March 2023 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 2016 sale was for 16% above the HPI. So the extrapolation line tracks at 16% above the HPI over time, until the March 2023 sale, where it falls to 6% above the HPI. The line then continues to track at 6% above the HPI.
