What might 7 BLACKBROOK be worth now?

7 BLACKBROOK might now be worth an estimated £140,425.

This is based on house price inflation of 429.9%, between February 1998 and May 2026, for terraced houses, in the Merthyr Tydfil local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 429.9% inflationary increase is applied to the most recent sale price for 7 BLACKBROOK of £26,500 on 26th February 1998. For the value to have increased from £26,500 to £140,425 over the 27 years and nine months to May 2026, the following assumptions must hold true:

  • The value of 7 BLACKBROOK has moved in line with the HPI for terraced houses in the Merthyr Tydfil local authority area.
  • The February 1998 sale price of £26,500 represented a fair market value for the property.
  • The size, condition, and specification of 7 BLACKBROOK has not materially changed since February 1998.
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.
