18 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 two 18 GRASS SLADE sales from January 2018 and June 2018 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 January 2018 sale was for 51% below the HPI. So the extrapolation line tracks at 51% below the HPI over time, until the June 2018 sale, where it rises to 34% below the HPI. The line then continues to track at 34% below the HPI.

What might 18 GRASS SLADE be worth now?

18 GRASS SLADE might now be worth an estimated £311,632.

This is based on house price inflation of 19.9%, between June 2018 and February 2025, 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 19.9% inflationary increase is applied to the most recent sale price for 18 GRASS SLADE of £260,000 on 6th June 2018. For the value to have increased from £260,000 to £311,632 over the seven years and four months to February 2025, the following assumptions must hold true:

• The June 2018 sale price of £260,000 represented a fair market value for the property.
