The below graph shows the average semi-detached house price in the Mole Valley local authority area over time, sourced from the HPI. The five 20 GREVILLE COURT sales between August 1995 and October 2024 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 October 2017 sale was for 36% below the HPI. So the extrapolation line tracks at 36% below the HPI over time, until the October 2024 sale, where it falls to 64% below the HPI. The line then continues to track at 64% below the HPI.

20 GREVILLE COURT might now be worth an estimated £198,186.
This is based on house price inflation of 1.6%, between October 2024 and August 2025, for semi-detached houses, in the Mole Valley local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).
The 1.6% inflationary increase is applied to the most recent sale price for 20 GREVILLE COURT of £195,000 on 28th October 2024. For the value to have increased from £195,000 to £198,186 over the one year and two months to August 2025, the following assumptions must hold true:
