20 NARROWBOAT LANE 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 three 20 NARROWBOAT LANE sales between March 2013 and May 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 November 2015 sale was for 40% below the HPI. So the extrapolation line tracks at 40% below the HPI over time, until the May 2019 sale, where it falls to 43% below the HPI.
