8 WEST STREET Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the North Northamptonshire local authority area over time, sourced from the HPI. The three 8 WEST STREET sales between December 2013 and September 2025 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 September 2020 sale was for 56% above the HPI. So the extrapolation line tracks at 56% above the HPI over time, until the September 2025 sale, where it rises to 57% above the HPI. The line then continues to track at 57% above the HPI.

What might 8 WEST STREET be worth now?

8 WEST STREET might now be worth an estimated £397,122.

This is based on house price inflation of 1.8%, between September 2025 and May 2026, for semi-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 1.8% inflationary increase is applied to the most recent sale price for 8 WEST STREET of £390,000 on 15th September 2025. For the value to have increased from £390,000 to £397,122 over the one year and four months to May 2026, the following assumptions must hold true:

• The value of 8 WEST STREET has moved in line with the HPI for semi-detached houses in the North Northamptonshire local authority area.
• The September 2025 sale price of £390,000 represented a fair market value for the property.
