The below graph shows the average detached house price in the Sevenoaks local authority area over time, sourced from the HPI. The five 15 OLD DOWNS sales between March 1997 and July 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 2016 sale was for 8% below the HPI. So the extrapolation line tracks at 8% below the HPI over time, until the July 2022 sale, which was also at 8% below the HPI.

What might 15 OLD DOWNS be worth now?
