The below graph shows the average terraced house price in the Harrow local authority area over time, sourced from the HPI. The three 41 AVONDALE ROAD sales between March 1999 and June 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 April 2006 sale was for 6% below the HPI. So the extrapolation line tracks at 6% below the HPI over time, until the June 2010 sale, where it falls to 12% below the HPI. The line then continues to track at 12% below the HPI.

41 AVONDALE ROAD might now be worth an estimated £486,031.
