What might 21 OTTAWA CLOSE be worth now?

21 OTTAWA CLOSE might now be worth an estimated £368,751.

This is based on house price inflation of 67.6%, between August 2011 and April 2026, for detached houses, in the Blackburn with Darwen local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 67.6% inflationary increase is applied to the most recent sale price for 21 OTTAWA CLOSE of £220,000 on 12th August 2011. For the value to have increased from £220,000 to £368,751 over the fifteen years and four months to April 2026, the following assumptions must hold true:

  • The value of 21 OTTAWA CLOSE has moved in line with the HPI for detached houses in the Blackburn with Darwen local authority area.
  • The August 2011 sale price of £220,000 represented a fair market value for the property.
  • The size, condition, and specification of 21 OTTAWA CLOSE has not materially changed since August 2011.
