21 TUNNEL WOOD ROAD Price Paid vs. HPI Average

The below graph shows the average detached house price in the Watford local authority area over time, sourced from the HPI. The three 21 TUNNEL WOOD ROAD sales between April 2006 and October 2017 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 2008 sale was for 54% above the HPI. So the extrapolation line tracks at 54% above the HPI over time, until the October 2017 sale, where it falls to 45% above the HPI.
