20 WALWYN CLOSE Price Paid vs. HPI Average

The below graph shows the average detached house price in the Chichester local authority area over time, sourced from the HPI. The three 20 WALWYN CLOSE sales between April 2000 and July 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 April 2013 sale was for 10% above the HPI. So the extrapolation line tracks at 10% above the HPI over time, until the July 2016 sale, where it falls to 8% below the HPI. The line then continues to track at 8% below the HPI.

What might 20 WALWYN CLOSE be worth now?
