The below graph shows the average semi-detached house price in the West Northamptonshire local authority area over time, sourced from the HPI. The two 12 BLACKWELL END sales from October 2003 and March 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 October 2003 sale was for 24% above the HPI. So the extrapolation line tracks at 24% above the HPI over time, until the March 2006 sale, where it falls to 16% above the HPI. The line then continues to track at 16% above the HPI.
12 BLACKWELL END might now be worth an estimated £330,162.

The 85.5% inflationary increase is applied to the most recent sale price for 12 BLACKWELL END of £178,000 on 24th March 2006. For the value to have increased from £178,000 to £330,162 over the nineteen years and one month to February 2025, the following assumptions must hold true:
