20 MARLBOROUGH 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 three 20 MARLBOROUGH AVENUE sales between February 1995 and August 2010 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 July 2007 sale was for 46% below the HPI. So the extrapolation line tracks at 46% below the HPI over time, until the August 2010 sale, where it falls to 53% below the HPI. The line then continues to track at 53% below the HPI.
