What might 12 CLOS ISLWYN be worth now?

12 CLOS ISLWYN might now be worth an estimated £330,028.

This is based on house price inflation of 53.5%, between February 2007 and May 2026, for detached houses, in the Swansea local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 53.5% inflationary increase is applied to the most recent sale price for 12 CLOS ISLWYN of £215,000 on 1st February 2007. For the value to have increased from £215,000 to £330,028 over the eighteen years and nine months to May 2026, the following assumptions must hold true:

  • The value of 12 CLOS ISLWYN has moved in line with the HPI for detached houses in the Swansea local authority area.
  • The February 2007 sale price of £215,000 represented a fair market value for the property.
  • The size, condition, and specification of 12 CLOS ISLWYN has not materially changed since February 2007.
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.
