What might 9 HEOL UCHAF be worth now?

9 HEOL UCHAF might now be worth an estimated £274,142.

This is based on house price inflation of 93.7%, between April 2011 and May 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 93.7% inflationary increase is applied to the most recent sale price for 9 HEOL UCHAF of £141,500 on 8th April 2011. For the value to have increased from £141,500 to £274,142 over the fourteen years and eleven months to May 2026, the following assumptions must hold true:

  • The value of 9 HEOL UCHAF has moved in line with the HPI for semi-detached houses in the Caerphilly local authority area.
  • The April 2011 sale price of £141,500 represented a fair market value for the property.
  • The size, condition, and specification of 9 HEOL UCHAF has not materially changed since April 2011.
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.
