What might BASEMENT FLAT be worth now?

BASEMENT FLAT might now be worth an estimated £1,421,768.

This is based on house price inflation of 67.3%, between May 2012 and April 2026, for terraced houses, in the Windsor and Maidenhead local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 67.3% inflationary increase is applied to the most recent sale price for BASEMENT FLAT of £850,000 on 4th May 2012. For the value to have increased from £850,000 to £1,421,768 over the fourteen years and one month to April 2026, the following assumptions must hold true:

  • The value of BASEMENT FLAT has moved in line with the HPI for terraced houses in the Windsor and Maidenhead local authority area.
  • The May 2012 sale price of £850,000 represented a fair market value for the property.
  • The size, condition, and specification of BASEMENT FLAT has not materially changed since May 2012.
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.
