18 DOLLIS AVENUE Price Paid vs. HPI Average

The below graph shows the average detached house price in the Barnet local authority area over time, sourced from the HPI. The two 18 DOLLIS AVENUE sales from June 2002 and October 2022 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 June 2002 sale was for 39% above the HPI. So the extrapolation line tracks at 39% above the HPI over time, until the October 2022 sale, where it rises to 74% above the HPI. The line then continues to track at 74% above the HPI.
