8 GRASS SLADE Price Paid vs. HPI Average

The below graph shows the average detached house price in the West Northamptonshire local authority area over time, sourced from the HPI. The three 8 GRASS SLADE sales between September 1995 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 October 2017 sale was for 39% below the HPI. So the extrapolation line tracks at 39% below the HPI over time, until the September 2025 sale, where it rises to 37% below the HPI. The line then continues to track at 37% below the HPI.

What might 8 GRASS SLADE be worth now?

This is based on house price deflation of 0.3%, between September 2025 and May 2026, for 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 0.3% deflationary decrease is applied to the most recent sale price for 8 GRASS SLADE of £300,000 on 3rd September 2025. For the value to have decreased from £300,000 to £298,953 over the one year and four months to May 2026, the following assumptions must hold true:
