What might MILL POND HOUSE be worth now?

MILL POND HOUSE might now be worth an estimated £961,989.

This is based on house price inflation of 92.4%, between October 2009 and May 2026, for detached houses, in the Newport local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 92.4% inflationary increase is applied to the most recent sale price for MILL POND HOUSE of £499,995 on 1st October 2009. For the value to have increased from £499,995 to £961,989 over the seventeen years and five months to May 2026, the following assumptions must hold true:

  • The value of MILL POND HOUSE has moved in line with the HPI for detached houses in the Newport local authority area.
  • The October 2009 sale price of £499,995 represented a fair market value for the property.
  • The size, condition, and specification of MILL POND HOUSE has not materially changed since October 2009.
