30 DECOY 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 three 30 DECOY AVENUE sales between July 2006 and February 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 2013 sale was for 50% above the HPI. So the extrapolation line tracks at 50% above the HPI over time, until the February 2024 sale, where it falls to 19% above the HPI. The line then continues to track at 19% above the HPI.
