The below graph shows the average terraced house price in the North Northamptonshire local authority area over time, sourced from the HPI. The four 70 DUKE STREET sales between June 2005 and March 2016 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 2009 sale was for 12% above the HPI. So the extrapolation line tracks at 12% above the HPI over time, until the March 2016 sale, where it falls to 8% below the HPI. The line then continues to track at 8% below the HPI.

70 DUKE STREET might now be worth an estimated £187,105.
This is based on house price inflation of 55.9%, between March 2016 and May 2026, 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 55.9% inflationary increase is applied to the most recent sale price for 70 DUKE STREET of £120,000 on 22nd March 2016. For the value to have increased from £120,000 to £187,105 over the nine years and ten months to May 2026, the following assumptions must hold true:
