9 MALLARD 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 two 9 MALLARD CLOSE sales from April 2003 and September 2016 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 April 2003 sale was for 13% below the HPI. So the extrapolation line tracks at 13% below the HPI over time, until the September 2016 sale, where it falls to 21% below the HPI. The line then continues to track at 21% below the HPI.

What might 9 MALLARD CLOSE be worth now?
