What might 18 BISCAY CLOSE be worth now?

18 BISCAY CLOSE might now be worth an estimated £549,901.

This is based on house price inflation of 100%, between November 2009 and April 2026, for detached houses, in the North Northamptonshire local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 100% inflationary increase is applied to the most recent sale price for 18 BISCAY CLOSE of £275,000 on 30th November 2009. For the value to have increased from £275,000 to £549,901 over the seventeen years and seven months to April 2026, the following assumptions must hold true:

  • The value of 18 BISCAY CLOSE has moved in line with the HPI for detached houses in the North Northamptonshire local authority area.
  • The November 2009 sale price of £275,000 represented a fair market value for the property.
  • The size, condition, and specification of 18 BISCAY CLOSE has not materially changed since November 2009.
