The below graph shows the average semi-detached house price in the Tandridge local authority area over time, sourced from the HPI. The three 20 TILGATE COMMON sales between July 1998 and December 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 November 2017 sale was for 3% above the HPI. So the extrapolation line tracks at 3% above the HPI over time, until the December 2024 sale, where it rises to 6% above the HPI. The line then continues to track at 6% above the HPI.

20 TILGATE COMMON might now be worth an estimated £511,307.
This is based on house price deflation of 0.7%, between December 2024 and April 2026, for semi-detached houses, in the Tandridge local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).
The 0.7% deflationary decrease is applied to the most recent sale price for 20 TILGATE COMMON of £515,000 on 11th December 2024. For the value to have decreased from £515,000 to £511,307 over the two years and eight months to April 2026, the following assumptions must hold true:
