9 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 four 9 GRASS SLADE sales between March 1997 and April 2010 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 March 2001 sale was for 47% below the HPI. So the extrapolation line tracks at 47% below the HPI over time, until the April 2010 sale, where it rises to 35% below the HPI. The line then continues to track at 35% below the HPI.

What might 9 GRASS SLADE be worth now?

9 GRASS SLADE might now be worth an estimated £308,334.

This is based on house price inflation of 76.2%, between April 2010 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 76.2% inflationary increase is applied to the most recent sale price for 9 GRASS SLADE of £174,995 on 12th April 2010. For the value to have increased from £174,995 to £308,334 over the fifteen years and two months to February 2025, the following assumptions must hold true:

• The value of 9 GRASS SLADE has moved in line with the HPI for detached houses in the West Northamptonshire local authority area.
• The April 2010 sale price of £174,995 represented a fair market value for the property.
