FLAT 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 FLAT sales from October 2002 and February 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 October 2002 sale was for 33% above the HPI. So the extrapolation line tracks at 33% above the HPI over time, until the February 2003 sale, where it rises to 50% above the HPI. The line then continues to track at 50% above the HPI.

What might FLAT be worth now?

FLAT might now be worth an estimated £428,104.

This is based on house price inflation of 135.9%, between February 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 135.9% inflationary increase is applied to the most recent sale price for FLAT of £181,500 on 21st February 2003. For the value to have increased from £181,500 to £428,104 over the 22 years to February 2025, the following assumptions must hold true:

• The value of FLAT has moved in line with the HPI for semi-detached houses in the West Northamptonshire local authority area.
• The February 2003 sale price of £181,500 represented a fair market value for the property.
• The size, condition, and specification of FLAT has not materially changed since February 2003.
