31 GRAYS LANE Price Paid vs. HPI Average

The below graph shows the average detached house price in the Mole Valley local authority area over time, sourced from the HPI. The two 31 GRAYS LANE sales from March 1995 and December 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 March 1995 sale was for 25% above the HPI. So the extrapolation line tracks at 25% above the HPI over time, until the December 2010 sale, where it rises to 155% above the HPI. The line then continues to track at 155% above the HPI.

What might 31 GRAYS LANE be worth now?

31 GRAYS LANE might now be worth an estimated £2,449,909.

This is based on house price inflation of 61.2%, between December 2010 and August 2025, for 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 61.2% inflationary increase is applied to the most recent sale price for 31 GRAYS LANE of £1,520,000 on 7th December 2010. For the value to have increased from £1,520,000 to £2,449,909 over the fifteen years and four months to August 2025, the following assumptions must hold true:

• The value of 31 GRAYS LANE has moved in line with the HPI for detached houses in the Mole Valley local authority area.
• The December 2010 sale price of £1,520,000 represented a fair market value for the property.
