The below graph shows the average terraced house price in the North Northamptonshire local authority area over time, sourced from the HPI. The four 71 KING STREET sales between July 1995 and May 2004 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 2000 sale was for 10% below the HPI. So the extrapolation line tracks at 10% below the HPI over time, until the May 2004 sale, where it rises to 13% above the HPI. The line then continues to track at 13% above the HPI.

71 KING STREET might now be worth an estimated £231,930.
This is based on house price inflation of 132%, between May 2004 and August 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).
