The below graph shows the average terraced house price in the North Northamptonshire local authority area over time, sourced from the HPI. The three 15 TREEN CLOSE sales between July 2006 and June 2021 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 October 2014 sale was for 2% above the HPI. So the extrapolation line tracks at 2% above the HPI over time, until the June 2021 sale, where it rises to 4% above the HPI. The line then continues to track at 4% above the HPI.

15 TREEN CLOSE might now be worth an estimated £209,788.
This is based on house price inflation of 15%, between June 2021 and July 2025, for terraced 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 15% inflationary increase is applied to the most recent sale price for 15 TREEN CLOSE of £182,500 on 25th June 2021. For the value to have increased from £182,500 to £209,788 over the three years and eleven months to July 2025, the following assumptions must hold true:
