20 DERWENT 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 three 20 DERWENT AVENUE sales between February 1998 and August 2015 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 June 2006 sale was for 30% below the HPI. So the extrapolation line tracks at 30% below the HPI over time, until the August 2015 sale, where it rises to 6% below the HPI. The line then continues to track at 6% below the HPI.
