What might 1 DELLS be worth now?

1 DELLS might now be worth an estimated £431,442.

This is based on house price inflation of 439.3%, between March 1999 and July 2026, for semi-detached houses, in the Milton Keynes local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 439.3% inflationary increase is applied to the most recent sale price for 1 DELLS of £80,000 on 4th March 1999. For the value to have increased from £80,000 to £431,442 over the 26 years and eight months to July 2026, the following assumptions must hold true:

  • The value of 1 DELLS has moved in line with the HPI for semi-detached houses in the Milton Keynes local authority area.
  • The March 1999 sale price of £80,000 represented a fair market value for the property.
  • The size, condition, and specification of 1 DELLS has not materially changed since March 1999.
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.
