21 CONNAUGHT AVENUE Price Paid vs. HPI Average

The below graph shows the average detached house price in the Thurrock local authority area over time, sourced from the HPI. The two 21 CONNAUGHT AVENUE sales from November 2011 and June 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 November 2011 sale was for 36% above the HPI. So the extrapolation line tracks at 36% above the HPI over time, until the June 2023 sale, where it falls to 34% above the HPI. The line then continues to track at 34% above the HPI.
