17 HALL CLOSE 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 17 HALL CLOSE sales from June 2000 and March 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 June 2000 sale was for 35% above the HPI. So the extrapolation line tracks at 35% above the HPI over time, until the March 2006 sale, where it rises to 50% above the HPI. The line then continues to track at 50% above the HPI.

What might 17 HALL CLOSE be worth now?

This is based on house price inflation of 86.2%, between March 2006 and August 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 86.2% inflationary increase is applied to the most recent sale price for 17 HALL CLOSE of £382,500 on 14th March 2006. For the value to have increased from £382,500 to £712,253 over the eighteen years and seven months to August 2025, the following assumptions must hold true:
