31 HARTWELL ROAD 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 31 HARTWELL ROAD sales between June 1997 and May 2022 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 January 2006 sale was for 24% above the HPI. So the extrapolation line tracks at 24% above the HPI over time, until the May 2022 sale, where it falls to 13% above the HPI. The line then continues to track at 13% above the HPI.

What might 31 HARTWELL ROAD be worth now?
