11 HELDEN AVENUE Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the Castle Point local authority area over time, sourced from the HPI. The three 11 HELDEN AVENUE sales between August 2000 and July 2023 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 January 2019 sale was for 35% below the HPI. So the extrapolation line tracks at 35% below the HPI over time, until the July 2023 sale, where it rises to 25% below the HPI. The line then continues to track at 25% below the HPI.
