11 HARMSWORTH WAY Price Paid vs. HPI Average

The below graph shows the average detached house price in the Barnet local authority area over time, sourced from the HPI. The two 11 HARMSWORTH WAY sales from March 2010 and August 2012 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 2010 sale was for 241% above the HPI. So the extrapolation line tracks at 241% above the HPI over time, until the August 2012 sale, where it rises to 269% above the HPI.
