The below graph shows the average terraced house price in the North Northamptonshire local authority area over time, sourced from the HPI. The three 121 BARNWELL STREET sales between June 1999 and January 2020 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 2007 sale was for 3% below the HPI. So the extrapolation line tracks at 3% below the HPI over time, until the January 2020 sale, where it rises to roughly the same level as the HPI. The line then continues to track in line with the HPI.

121 BARNWELL STREET might now be worth an estimated £205,477.
This is based on house price inflation of 30.5%, between January 2020 and August 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 30.5% inflationary increase is applied to the most recent sale price for 121 BARNWELL STREET of £157,500 on 15th January 2020. For the value to have increased from £157,500 to £205,477 over the four years and five months to August 2025, the following assumptions must hold true:
