What might 18A ALLERGATE be worth now?

18A ALLERGATE might now be worth an estimated £160,499.

This is based on house price inflation of 7%, between March 2009 and April 2026, for flats, in the County Durham local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 7% inflationary increase is applied to the most recent sale price for 18A ALLERGATE of £150,000 on 31st March 2009. For the value to have increased from £150,000 to £160,499 over the sixteen years and eleven months to April 2026, the following assumptions must hold true:

  • The value of 18A ALLERGATE has moved in line with the HPI for flats in the County Durham local authority area.
  • The March 2009 sale price of £150,000 represented a fair market value for the property.
  • The size, condition, and specification of 18A ALLERGATE has not materially changed since March 2009.
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.
