46 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 five 46 SOUTHDOWN ROAD sales between June 1997 and July 2025 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 March 2003 sale was for 56% above the HPI. So the extrapolation line tracks at 56% above the HPI over time, until the July 2025 sale, where it falls to 3% below the HPI. The line then continues to track at 3% below the HPI.
