4 SEAGRAVE STREET 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 SEAGRAVE STREET sales from September 2011 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 September 2011 sale was for 23% below the HPI. So the extrapolation line tracks at 23% below the HPI over time, until the February 2025 sale, where it rises to 20% below the HPI. The line then continues to track at 20% below the HPI.
