The below graph shows the average detached house price in the North Northamptonshire local authority area over time, sourced from the HPI. The three 21 HARDEN CLOSE sales between November 1997 and August 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 January 1999 sale was for 28% above the HPI. So the extrapolation line tracks at 28% above the HPI over time, until the August 2015 sale, where it falls to 27% below the HPI. The line then continues to track at 27% below the HPI.

21 HARDEN CLOSE might now be worth an estimated £304,119.
This is based on house price inflation of 64.4%, between August 2015 and August 2025, for 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 64.4% inflationary increase is applied to the most recent sale price for 21 HARDEN CLOSE of £184,950 on 7th August 2015. For the value to have increased from £184,950 to £304,119 over the ten years to August 2025, the following assumptions must hold true:
