21 CHALMERS WAY Price Paid vs. HPI Average

The below graph shows the average detached house price in the Richmond upon Thames local authority area over time, sourced from the HPI. The two 21 CHALMERS WAY sales from August 2007 and September 2013 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 August 2007 sale was for 93% above the HPI. So the extrapolation line tracks at 93% above the HPI over time, until the September 2013 sale, where it rises to 118% above the HPI. The line then continues to track at 118% above the HPI.
