9 ARNSIDE CLOSE Price Paid vs. HPI Average

The below graph shows the average detached house price in the Adur local authority area over time, sourced from the HPI. The three 9 ARNSIDE CLOSE sales between June 2010 and March 2026 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 November 2021 sale was for 24% below the HPI. So the extrapolation line tracks at 24% below the HPI over time, until the March 2026 sale, where it rises to 14% below the HPI. The line then continues to track at 14% below the HPI.

What might 9 ARNSIDE CLOSE be worth now?
