BELSIZE 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 BELSIZE sales from July 1997 and July 2018 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 July 1997 sale was for 25% below the HPI. So the extrapolation line tracks at 25% below the HPI over time, until the July 2018 sale, where it rises to 2% above the HPI. The line then continues to track at 2% above the HPI.

What might BELSIZE be worth now?

BELSIZE might now be worth an estimated £977,917.

This is based on house price inflation of 11.1%, between July 2018 and December 2024, 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 11.1% inflationary increase is applied to the most recent sale price for BELSIZE of £880,000 on 2nd July 2018. For the value to have increased from £880,000 to £977,917 over the five years and seven months to December 2024, the following assumptions must hold true:

• The value of BELSIZE has moved in line with the HPI for detached houses in the Mole Valley local authority area.
• The July 2018 sale price of £880,000 represented a fair market value for the property.
• The size, condition, and specification of BELSIZE has not materially changed since July 2018.
