What might 40 WINDMILL CLOSE be worth now?

40 WINDMILL CLOSE might now be worth an estimated £474,278.

This is based on house price inflation of 9%, between July 2024 and May 2026, for semi-detached houses, in the North Hertfordshire local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 9% inflationary increase is applied to the most recent sale price for 40 WINDMILL CLOSE of £435,000 on 26th July 2024. For the value to have increased from £435,000 to £474,278 over the two years and two months to May 2026, the following assumptions must hold true:

  • The value of 40 WINDMILL CLOSE has moved in line with the HPI for semi-detached houses in the North Hertfordshire local authority area.
  • The July 2024 sale price of £435,000 represented a fair market value for the property.
  • The size, condition, and specification of 40 WINDMILL CLOSE has not materially changed since July 2024.
