17 THORNFIELD AVENUE 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 17 THORNFIELD AVENUE sales from January 1999 and May 2009 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 January 1999 sale was for 59% below the HPI. So the extrapolation line tracks at 59% below the HPI over time, until the May 2009 sale, where it rises to 41% below the HPI.
