20 FARM 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 20 FARM AVENUE sales from July 1998 and September 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 July 1998 sale was for 69% above the HPI. So the extrapolation line tracks at 69% above the HPI over time, until the September 2022 sale, where it falls to 23% above the HPI. The line then continues to track at 23% above the HPI.
