21 WISLEY CLOSE 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 two 21 WISLEY CLOSE sales from October 1999 and August 2024 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 October 1999 sale was for 9% above the HPI. So the extrapolation line tracks at 9% above the HPI over time, until the August 2024 sale, where it falls to 14% below the HPI. The line then continues to track at 14% below the HPI.

What might 21 WISLEY CLOSE be worth now?
