18 GREEN CLOSE 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 three 18 GREEN CLOSE sales between February 2006 and February 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 October 2014 sale was for 5% below the HPI. So the extrapolation line tracks at 5% below the HPI over time, until the February 2019 sale, where it falls to 12% below the HPI. The line then continues to track at 12% below the HPI.
