The below graph shows the average semi-detached house price in the Sevenoaks local authority area over time, sourced from the HPI. The four 40 GREATNESS ROAD sales between February 1995 and October 2010 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 November 2007 sale was for 3% below the HPI. So the extrapolation line tracks at 3% below the HPI over time, until the October 2010 sale, where it rises to 2% above the HPI. The line then continues to track at 2% above the HPI.

40 GREATNESS ROAD might now be worth an estimated £535,242.
This is based on house price inflation of 88.5%, between October 2010 and July 2025, for semi-detached houses, in the Sevenoaks local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).
The 88.5% inflationary increase is applied to the most recent sale price for 40 GREATNESS ROAD of £284,000 on 29th October 2010. For the value to have increased from £284,000 to £535,242 over the fifteen years and three months to July 2025, the following assumptions must hold true:
