The below graph shows the average semi-detached house price in the West Northamptonshire local authority area over time, sourced from the HPI. The two 40 CHURCH STREET sales from April 2018 and July 2022 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 April 2018 sale was for 41% above the HPI. So the extrapolation line tracks at 41% above the HPI over time, until the July 2022 sale, where it rises to 51% above the HPI. The line then continues to track at 51% above the HPI.

40 CHURCH STREET might now be worth an estimated £434,424.
This is based on house price inflation of 5.6%, between July 2022 and August 2025, for semi-detached houses, in the West Northamptonshire local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).
The 5.6% inflationary increase is applied to the most recent sale price for 40 CHURCH STREET of £411,500 on 26th July 2022. For the value to have increased from £411,500 to £434,424 over the two years and eleven months to August 2025, the following assumptions must hold true:
