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 18 SENTINEL ROAD sales from September 2007 and September 2014 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 September 2007 sale was for 15% below the HPI. So the extrapolation line tracks at 15% below the HPI over time, until the September 2014 sale, where it rises to 3% below the HPI. The line then continues to track at 3% below the HPI.
18 SENTINEL ROAD might now be worth an estimated £276,791.

The 58.2% inflationary increase is applied to the most recent sale price for 18 SENTINEL ROAD of £174,950 on 2nd September 2014. For the value to have increased from £174,950 to £276,791 over the eleven years and seven months to February 2025, the following assumptions must hold true:
