23C ARTHUR ROAD 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 three 23C ARTHUR ROAD sales between October 1999 and December 2020 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 2006 sale was for 32% below the HPI. So the extrapolation line tracks at 32% below the HPI over time, until the December 2020 sale, where it falls to 38% below the HPI. The line then continues to track at 38% below the HPI.

What might 23C ARTHUR ROAD be worth now?
