1 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 1 GREEN CLOSE sales between June 2005 and April 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 March 2011 sale was for 8% below the HPI. So the extrapolation line tracks at 8% below the HPI over time, until the April 2019 sale, where it rises to roughly the same level as the HPI. The line then continues to track in line with the HPI.
