21 WESTFIELD Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the Mole Valley local authority area over time, sourced from the HPI. The two 21 WESTFIELD sales from December 2016 and December 2023 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 December 2016 sale was for 9% below the HPI. So the extrapolation line tracks at 9% below the HPI over time, until the December 2023 sale, where it rises to 10% above the HPI. The line then continues to track at 10% above the HPI.

What might 21 WESTFIELD be worth now?

21 WESTFIELD might now be worth an estimated £605,641.

This is based on house price deflation of 0.7%, between December 2023 and May 2026, 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 0.7% deflationary decrease is applied to the most recent sale price for 21 WESTFIELD of £610,000 on 8th December 2023. For the value to have decreased from £610,000 to £605,641 over the three years and seven months to May 2026, the following assumptions must hold true:

• The value of 21 WESTFIELD has moved in line with the HPI for semi-detached houses in the Mole Valley local authority area.
• The December 2023 sale price of £610,000 represented a fair market value for the property.
