The below graph shows the average detached house price in the Castle Point local authority area over time, sourced from the HPI. The two 42 WHERNSIDE AVENUE sales from July 2018 and June 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 July 2018 sale was for 42% below the HPI. So the extrapolation line tracks at 42% below the HPI over time, until the June 2025 sale, where it falls to 49% below the HPI. The line then continues to track at 49% below the HPI.

42 WHERNSIDE AVENUE might now be worth an estimated £256,103.
