The below graph shows the average semi-detached house price in the West Northamptonshire local authority area over time, sourced from the HPI. The four 21 SKINNER AVENUE sales between January 1997 and August 2013 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 2004 sale was for 15% below the HPI. So the extrapolation line tracks at 15% below the HPI over time, until the August 2013 sale, where it falls to 18% below the HPI. The line then continues to track at 18% below the HPI.

21 SKINNER AVENUE might now be worth an estimated £235,281.
This is based on house price inflation of 78.4%, between August 2013 and May 2026, for semi-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 78.4% inflationary increase is applied to the most recent sale price for 21 SKINNER AVENUE of £131,900 on 2nd August 2013. For the value to have increased from £131,900 to £235,281 over the thirteen years and three months to May 2026, the following assumptions must hold true:
