The below graph shows the average detached house price in the Worthing local authority area over time, sourced from the HPI. The three 9 ALLENDALE AVENUE sales between September 1998 and December 2019 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 2005 sale was for 68% above the HPI. So the extrapolation line tracks at 68% above the HPI over time, until the December 2019 sale, where it falls to 37% above the HPI. The line then continues to track at 37% above the HPI.
9 ALLENDALE AVENUE might now be worth an estimated £842,300.
This is based on house price inflation of 17.8%, between December 2019 and June 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).
