15 HILLSIDE WAY Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the West Northamptonshire local authority area over time, sourced from the HPI. The three 15 HILLSIDE WAY sales between January 1996 and October 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 January 1999 sale was for 49% above the HPI. So the extrapolation line tracks at 49% above the HPI over time, until the October 2013 sale, where it falls to 37% above the HPI. The line then continues to track at 37% above the HPI.

What might 15 HILLSIDE WAY be worth now?

The 74.4% inflationary increase is applied to the most recent sale price for 15 HILLSIDE WAY of £225,000 on 11th October 2013. For the value to have increased from £225,000 to £392,400 over the twelve years and eight months to February 2025, the following assumptions must hold true:
