21 DURHAM AVENUE Price Paid vs. HPI Average

The below graph shows the average detached house price in the Bromley local authority area over time, sourced from the HPI. The two 21 DURHAM AVENUE sales from February 1997 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 February 1997 sale was for 12% below the HPI. So the extrapolation line tracks at 12% below the HPI over time, until the September 2022 sale, where it rises to 9% below the HPI. The line then continues to track at 9% below the HPI.
