4 BLACKWELL CLOSE Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the West Northamptonshire local authority area over time, sourced from the HPI. The three 4 BLACKWELL CLOSE sales between June 2004 and March 2015 have been plotted on the graph. A line has been extrapolated to show what the value of the property might have been over time, following each sale, had it maintained the same margin above or below the HPI (as a percentage). For example, the June 2013 sale was for 4% above the HPI. So the extrapolation line tracks at 4% above the HPI over time, until the March 2015 sale, where it falls to 3% above the HPI. The line then continues to track at 3% above the HPI.

What might 4 BLACKWELL CLOSE be worth now?

4 BLACKWELL CLOSE might now be worth an estimated £293,918.

This is based on house price inflation of 57.8%, between March 2015 and May 2026, for semi-detached houses, in the West Northamptonshire local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 57.8% inflationary increase is applied to the most recent sale price for 4 BLACKWELL CLOSE of £186,250 on 30th March 2015. For the value to have increased from £186,250 to £293,918 over the ten years and ten months to May 2026, the following assumptions must hold true:

  • The value of 4 BLACKWELL CLOSE has moved in line with the HPI for semi-detached houses in the West Northamptonshire local authority area.
  • The March 2015 sale price of £186,250 represented a fair market value for the property.
  • The size, condition, and specification of 4 BLACKWELL CLOSE has not materially changed since March 2015.
