11 GAINSBOROUGH AVENUE Price Paid vs. HPI Average

The below graph shows the average detached house price in the Worthing local authority area over time, sourced from the HPI. The three 11 GAINSBOROUGH AVENUE sales between March 2004 and April 2021 have been plotted on the graph.

For example, the November 2014 sale was for 15% below the HPI. So the extrapolation line tracks at 15% below the HPI over time, until the April 2021 sale, where it falls to 23% below the HPI.
