31 PHILIP AVENUE Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the Sevenoaks local authority area over time, sourced from the HPI. The two 31 PHILIP AVENUE sales from March 2000 and May 2021 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 2000 sale was for 4% below the HPI. So the extrapolation line tracks at 4% below the HPI over time, until the May 2021 sale, which was also at 4% below the HPI.

What might 31 PHILIP AVENUE be worth now?
