51 WATERMILL WAY Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the West Northamptonshire local authority area over time, sourced from the HPI. The two 51 WATERMILL WAY sales from March 2023 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 March 2023 sale was for 60% below the HPI. So the extrapolation line tracks at 60% below the HPI over time, until the February 2025 sale, where it rises to 26% below the HPI. The line then continues to track at 26% below the HPI.

What might 51 WATERMILL WAY be worth now?
