20 AILSA ROAD 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 20 AILSA ROAD sales from May 2014 and May 2016 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 May 2014 sale was for 119% above the HPI. So the extrapolation line tracks at 119% above the HPI over time, until the May 2016 sale, which was also at 119% above the HPI.
