15 THORBURN ROAD 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 15 THORBURN ROAD sales from September 2002 and April 2021 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 2002 sale was for 99% above the HPI. So the extrapolation line tracks at 99% above the HPI over time, until the April 2021 sale, where it falls to 65% above the HPI. The line then continues to track at 65% above the HPI.

What might 15 THORBURN ROAD be worth now?
