22 BLACKMILE LANE Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the North Northamptonshire local authority area over time, sourced from the HPI. The two 22 BLACKMILE LANE sales from May 2002 and May 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 May 2002 sale was for 91% above the HPI. So the extrapolation line tracks at 91% above the HPI over time, until the May 2015 sale, where it rises to 117% above the HPI. The line then continues to track at 117% above the HPI.

What might 22 BLACKMILE LANE be worth now?

This is based on house price inflation of 70.1%, between May 2015 and February 2025, 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 70.1% inflationary increase is applied to the most recent sale price for 22 BLACKMILE LANE of £321,000 on 22nd May 2015. For the value to have increased from £321,000 to £545,955 over the ten years and three months to February 2025, the following assumptions must hold true:
