What might 12A ALLERGATE be worth now?

12A ALLERGATE might now be worth an estimated £133,790.

This is based on house price inflation of 4.5%, between September 2021 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 4.5% inflationary increase is applied to the most recent sale price for 12A ALLERGATE of £128,000 on 13th September 2021. For the value to have increased from £128,000 to £133,790 over the five years and five months to April 2026, the following assumptions must hold true:

  • The value of 12A ALLERGATE has moved in line with the HPI for flats in the County Durham local authority area.
  • The September 2021 sale price of £128,000 represented a fair market value for the property.
  • The size, condition, and specification of 12A ALLERGATE has not materially changed since September 2021.
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.
