31 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 two 31 FURNACE LANE sales from November 2004 and July 2011 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 November 2004 sale was for 31% below the HPI. So the extrapolation line tracks at 31% below the HPI over time, until the July 2011 sale, where it rises to 16% below the HPI. The line then continues to track at 16% below the HPI.

What might 31 FURNACE LANE be worth now?

This is based on house price inflation of 84.7%, between July 2011 and February 2025, 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 84.7% inflationary increase is applied to the most recent sale price for 31 FURNACE LANE of £130,000 on 1st July 2011. For the value to have increased from £130,000 to £240,166 over the fourteen years and five months to February 2025, the following assumptions must hold true:
