21 WHITTLEBURY 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 21 WHITTLEBURY ROAD sales between September 1997 and February 2025 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 August 2019 sale was for 19% above the HPI. So the extrapolation line tracks at 19% above the HPI over time, until the February 2025 sale, where it falls to 2% above the HPI. The line then continues to track at 2% above the HPI.
