What might 9 CASTLE ACRE be worth now?

9 CASTLE ACRE might now be worth an estimated £378,438.

This is based on house price inflation of 332.5%, between December 2000 and May 2026, for terraced 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 332.5% inflationary increase is applied to the most recent sale price for 9 CASTLE ACRE of £87,500 on 18th December 2000. For the value to have increased from £87,500 to £378,438 over the 26 years and seven months to May 2026, the following assumptions must hold true:

  • The value of 9 CASTLE ACRE has moved in line with the HPI for terraced houses in the Swansea local authority area.
  • The December 2000 sale price of £87,500 represented a fair market value for the property.
  • The size, condition, and specification of 9 CASTLE ACRE has not materially changed since December 2000.
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.
