9 ARDENS GROVE 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 9 ARDENS GROVE sales from December 2017 and August 2019 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 December 2017 sale was for 43% below the HPI. So the extrapolation line tracks at 43% below the HPI over time, until the August 2019 sale, where it rises to 10% below the HPI. The line then continues to track at 10% below the HPI.

What might 9 ARDENS GROVE be worth now?
