What might 40 DOWNS AVENUE be worth now?

40 DOWNS AVENUE might now be worth an estimated £850,497.

This is based on house price inflation of 183.5%, between July 2002 and May 2026, for semi-detached houses, in the Harrow local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 183.5% inflationary increase is applied to the most recent sale price for 40 DOWNS AVENUE of £299,950 on 12th July 2002. For the value to have increased from £299,950 to £850,497 over the 24 years and two months to May 2026, the following assumptions must hold true:

  • The value of 40 DOWNS AVENUE has moved in line with the HPI for semi-detached houses in the Harrow local authority area.
  • The July 2002 sale price of £299,950 represented a fair market value for the property.
  • The size, condition, and specification of 40 DOWNS AVENUE has not materially changed since July 2002.
Disclaimer: Please note that this is a theoretical estimate based on assumptions which may or may not be correct. It should not be relied on for any purpose.
