The below graph shows the average detached house price in the Worthing local authority area over time, sourced from the HPI. The two 49 COPTHORNE HILL sales from May 1996 and November 1996 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 1996 sale was for 12% below the HPI. So the extrapolation line tracks at 12% below the HPI over time, until the November 1996 sale, where it falls to 30% below the HPI. The line then continues to track at 30% below the HPI.
