21 POLAR STAR CLOSE 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 four 21 POLAR STAR CLOSE sales between May 2001 and December 2018 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 August 2018 sale was for 37% below the HPI. So the extrapolation line tracks at 37% below the HPI over time, until the December 2018 sale, where it rises to 31% below the HPI. The line then continues to track at 31% below the HPI.

What might 21 POLAR STAR CLOSE be worth now?
