20 SOUTHDOWN ROAD Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the Arun local authority area over time, sourced from the HPI. The three 20 SOUTHDOWN ROAD sales between April 2000 and March 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 February 2005 sale was for 19% above the HPI. So the extrapolation line tracks at 19% above the HPI over time, until the March 2016 sale, where it falls to 9% above the HPI. The line then continues to track at 9% above the HPI.

What might 20 SOUTHDOWN ROAD be worth now?
