What might 23 MILL ROAD be worth now?

23 MILL ROAD might now be worth an estimated £291,728.

This is based on house price inflation of 101.2%, between July 2012 and May 2026, for semi-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 101.2% inflationary increase is applied to the most recent sale price for 23 MILL ROAD of £145,000 on 6th July 2012. For the value to have increased from £145,000 to £291,728 over the fourteen years and two months to May 2026, the following assumptions must hold true:

  • The value of 23 MILL ROAD has moved in line with the HPI for semi-detached houses in the North Northamptonshire local authority area.
  • The July 2012 sale price of £145,000 represented a fair market value for the property.
  • The size, condition, and specification of 23 MILL ROAD has not materially changed since July 2012.
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.
