4 MALLARD CLOSE 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 4 MALLARD CLOSE sales from July 2009 and May 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 July 2009 sale was for 48% below the HPI. So the extrapolation line tracks at 48% below the HPI over time, until the May 2025 sale, where it rises to 47% below the HPI. The line then continues to track at 47% below the HPI.
