The below graph shows the average semi-detached house price in the Castle Point local authority area over time, sourced from the HPI. The two 21 WHERNSIDE AVENUE sales from August 2014 and February 2020 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 August 2014 sale was for 91% below the HPI. So the extrapolation line tracks at 91% below the HPI over time, until the February 2020 sale, where it rises to 29% below the HPI. The line then continues to track at 29% below the HPI.
21 WHERNSIDE AVENUE might now be worth an estimated £249,276.
This is based on house price inflation of 22%, between February 2020 and December 2024, for semi-detached houses, in the Castle Point local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).
