20 WESTLAND AVENUE Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the Worthing local authority area over time, sourced from the HPI. The four 20 WESTLAND AVENUE sales between January 2015 and May 2022 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 2021 sale was for 10% above the HPI. So the extrapolation line tracks at 10% above the HPI over time, until the May 2022 sale, where it falls to 4% above the HPI. The line then continues to track at 4% above the HPI.

What might 20 WESTLAND AVENUE be worth now?
