What might 13 BRYN CASEG be worth now?

13 BRYN CASEG might now be worth an estimated £380,345.

This is based on house price inflation of 56.5%, between May 2014 and May 2026, for detached houses, in the Gwynedd local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 56.5% inflationary increase is applied to the most recent sale price for 13 BRYN CASEG of £243,000 on 22nd May 2014. For the value to have increased from £243,000 to £380,345 over the twelve years to May 2026, the following assumptions must hold true:

  • The value of 13 BRYN CASEG has moved in line with the HPI for detached houses in the Gwynedd local authority area.
  • The May 2014 sale price of £243,000 represented a fair market value for the property.
  • The size, condition, and specification of 13 BRYN CASEG has not materially changed since May 2014.
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.
