21 TREEN CLOSE Price Paid vs. HPI Average

The below graph shows the average terraced house price in the North Northamptonshire local authority area over time, sourced from the HPI. The two 21 TREEN CLOSE sales from November 1996 and June 2002 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 1996 sale was for 20% above the HPI. So the extrapolation line tracks at 20% above the HPI over time, until the June 2002 sale, where it falls to 13% above the HPI. The line then continues to track at 13% above the HPI.

What might 21 TREEN CLOSE be worth now?

This is based on house price inflation of 241.9%, between June 2002 and July 2025, for terraced houses, in the North Northamptonshire local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 241.9% inflationary increase is applied to the most recent sale price for 21 TREEN CLOSE of £66,750 on 14th June 2002. For the value to have increased from £66,750 to £228,233 over the 22 years and eleven months to July 2025, the following assumptions must hold true:
