The below graph shows the average detached house price in the Barnet local authority area over time, sourced from the HPI. The four 15 WEST HEATH AVENUE sales between September 2001 and December 2022 have been plotted on the graph.

For example, the May 2017 sale was for 176% above the HPI. So the extrapolation line tracks at 176% above the HPI over time, until the December 2022 sale, where it rises to 292% above the HPI.
