9 BELLFIELD AVENUE Price Paid vs. HPI Average

The below graph shows the average detached house price in the Harrow local authority area over time, sourced from the HPI. The two 9 BELLFIELD AVENUE sales from September 2010 and September 2011 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 September 2010 sale was for 18% below the HPI. So the extrapolation line tracks at 18% below the HPI over time, until the September 2011 sale, where it rises to 8% above the HPI. The line then continues to track at 8% above the HPI.
