16 OLD 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 16 OLD CLOSE sales from August 2001 and August 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 August 2001 sale was for 54% above the HPI. So the extrapolation line tracks at 54% above the HPI over time, until the August 2006 sale, where it falls to 20% above the HPI. The line then continues to track at 20% above the HPI.

What might 16 OLD CLOSE be worth now?

This is based on house price inflation of 76%, between August 2006 and April 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 76% inflationary increase is applied to the most recent sale price for 16 OLD CLOSE of £325,000 on 16th August 2006. For the value to have increased from £325,000 to £571,966 over the twenty years and four months to April 2026, the following assumptions must hold true:
