18 GREVILLE AVENUE 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 GREVILLE AVENUE sales from November 2001 and June 2006 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 November 2001 sale was for 38% below the HPI. So the extrapolation line tracks at 38% below the HPI over time, until the June 2006 sale, where it falls to 39% below the HPI. The line then continues to track at 39% below the HPI.

What might 18 GREVILLE AVENUE be worth now?

This is based on house price inflation of 78.8%, between June 2006 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 78.8% inflationary increase is applied to the most recent sale price for 18 GREVILLE AVENUE of £163,000 on 2nd June 2006. For the value to have increased from £163,000 to £291,393 over the nineteen years and four months to February 2025, the following assumptions must hold true:
