47 FURNACE LANE 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 47 FURNACE LANE sales between November 1997 and December 2003 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 March 2001 sale was for 11% below the HPI. So the extrapolation line tracks at 11% below the HPI over time, until the December 2003 sale, where it rises to 9% below the HPI. The line then continues to track at 9% below the HPI.

What might 47 FURNACE LANE be worth now?

The 113.1% inflationary increase is applied to the most recent sale price for 47 FURNACE LANE of £122,250 on 11th December 2003. For the value to have increased from £122,250 to £260,503 over the 22 years and ten months to February 2025, the following assumptions must hold true:
