27 IRONSTONE 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 27 IRONSTONE LANE sales from May 1997 and March 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 May 1997 sale was for 55% below the HPI. So the extrapolation line tracks at 55% below the HPI over time, until the March 2014 sale, where it rises to 22% below the HPI. The line then continues to track at 22% below the HPI.

What might 27 IRONSTONE LANE be worth now?

27 IRONSTONE LANE might now be worth an estimated £221,905.

This is based on house price inflation of 69.4%, between March 2014 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 69.4% inflationary increase is applied to the most recent sale price for 27 IRONSTONE LANE of £131,000 on 11th March 2014. For the value to have increased from £131,000 to £221,905 over the eleven years and one month to February 2025, the following assumptions must hold true:
