What might 11 UPPER TAIL be worth now?

11 UPPER TAIL might now be worth an estimated £772,909.

This is based on house price inflation of 98.2%, between January 2007 and May 2026, for detached houses, in the Three Rivers local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 98.2% inflationary increase is applied to the most recent sale price for 11 UPPER TAIL of £390,000 on 19th January 2007. For the value to have increased from £390,000 to £772,909 over the eighteen years and eight months to May 2026, the following assumptions must hold true:

  • The value of 11 UPPER TAIL has moved in line with the HPI for detached houses in the Three Rivers local authority area.
  • The January 2007 sale price of £390,000 represented a fair market value for the property.
  • The size, condition, and specification of 11 UPPER TAIL has not materially changed since January 2007.
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.
