6 RADNOR 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 6 RADNOR AVENUE sales from September 1999 and May 2005 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 1999 sale was for 32% below the HPI. So the extrapolation line tracks at 32% below the HPI over time, until the May 2005 sale, where it rises to 21% above the HPI. The line then continues to track at 21% above the HPI.
