The below graph shows the average detached house price in the Barnet local authority area over time, sourced from the HPI. The two 18 WEST HEATH AVENUE sales from March 2008 and June 2024 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 March 2008 sale was for 599% above the HPI. So the extrapolation line tracks at 599% above the HPI over time, until the June 2024 sale, where it falls to 394% above the HPI.
