20 SERPENTINE ROAD Price Paid vs. HPI Average

The below graph shows the average detached house price in the Sevenoaks local authority area over time, sourced from the HPI. The three 20 SERPENTINE ROAD sales between February 1995 and April 2025 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 June 1997 sale was for 27% above the HPI. So the extrapolation line tracks at 27% above the HPI over time, until the April 2025 sale, where it falls to 6% below the HPI. The line then continues to track at 6% below the HPI.
