21 SOUTH COPSE 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 five 21 SOUTH COPSE sales between March 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 May 2024 sale was for 30% below the HPI. So the extrapolation line tracks at 30% below the HPI over time, until the August 2024 sale, where it falls to 32% below the HPI. The line then continues to track at 32% below the HPI.

What might 21 SOUTH COPSE be worth now?
