What might 20 MOUNTAIN VIEW be worth now?

20 MOUNTAIN VIEW might now be worth an estimated £185,456.

This is based on house price inflation of 9.1%, between November 2023 and July 2026, for semi-detached houses, in the Caerphilly local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 9.1% inflationary increase is applied to the most recent sale price for 20 MOUNTAIN VIEW of £170,000 on 17th November 2023. For the value to have increased from £170,000 to £185,456 over the three years and four months to July 2026, the following assumptions must hold true:

  • The value of 20 MOUNTAIN VIEW has moved in line with the HPI for semi-detached houses in the Caerphilly local authority area.
  • The November 2023 sale price of £170,000 represented a fair market value for the property.
  • The size, condition, and specification of 20 MOUNTAIN VIEW has not materially changed since November 2023.
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.
