8 FOUNDRY AVENUE 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 8 FOUNDRY AVENUE sales from June 2021 and February 2026 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 June 2021 sale was for 29% above the HPI. So the extrapolation line tracks at 29% above the HPI over time, until the February 2026 sale, where it falls to 11% above the HPI. The line then continues to track at 11% above the HPI.
