The below graph shows the average detached house price in the Worthing local authority area over time, sourced from the HPI. The four 15 FIRST AVENUE sales between March 2005 and November 2021 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 2021 sale was for 119% above the HPI. So the extrapolation line tracks at 119% above the HPI over time, until the November 2021 sale, where it rises to 146% above the HPI. The line then continues to track at 146% above the HPI.

15 FIRST AVENUE might now be worth an estimated £1,504,536.
This is based on house price inflation of 0.3%, between November 2021 and August 2025, for detached houses, in the Worthing local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).
