10 PORTSMOUTH AVENUE Price Paid vs. HPI Average

The below graph shows the average detached house price in the Elmbridge local authority area over time, sourced from the HPI. The two 10 PORTSMOUTH AVENUE sales from May 2013 and November 2019 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 2013 sale was for 60% above the HPI. So the extrapolation line tracks at 60% above the HPI over time, until the November 2019 sale, where it rises to 80% above the HPI. The line then continues to track at 80% above the HPI.
