4 BROOK 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 4 BROOK LANE sales between April 1998 and September 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 January 2002 sale was for 31% above the HPI. So the extrapolation line tracks at 31% above the HPI over time, until the September 2003 sale, where it falls to 8% above the HPI. The line then continues to track at 8% above the HPI.

What might 4 BROOK LANE be worth now?

4 BROOK LANE might now be worth an estimated £309,879.

This is based on house price inflation of 115.9%, between September 2003 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 115.9% inflationary increase is applied to the most recent sale price for 4 BROOK LANE of £143,500 on 4th September 2003. For the value to have increased from £143,500 to £309,879 over the 22 years and seven months to February 2025, the following assumptions must hold true:
