The below graph shows the average semi-detached house price in the West Northamptonshire local authority area over time, sourced from the HPI. The three 18 WILLIAMS TERRACE sales between April 2013 and June 2023 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 August 2019 sale was for 17% below the HPI. So the extrapolation line tracks at 17% below the HPI over time, until the June 2023 sale, where it rises to 4% above the HPI. The line then continues to track at 4% above the HPI.

18 WILLIAMS TERRACE might now be worth an estimated £296,359.
This is based on house price inflation of 5.8%, between June 2023 and May 2026, 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 5.8% inflationary increase is applied to the most recent sale price for 18 WILLIAMS TERRACE of £280,000 on 7th June 2023. For the value to have increased from £280,000 to £296,359 over the three years and one month to May 2026, the following assumptions must hold true:
