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 248 WINDMILL AVENUE sales from November 2006 and September 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 November 2006 sale was for 18% below the HPI. So the extrapolation line tracks at 18% below the HPI over time, until the September 2015 sale, where it rises to 4% below the HPI. The line then continues to track at 4% below the HPI.

248 WINDMILL AVENUE might now be worth an estimated £246,129.
This is based on house price inflation of 68.6%, between September 2015 and August 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 68.6% inflationary increase is applied to the most recent sale price for 248 WINDMILL AVENUE of £146,000 on 3rd September 2015. For the value to have increased from £146,000 to £246,129 over the ten years and one month to August 2025, the following assumptions must hold true:
