18 SOUTHBROOK Price Paid vs. HPI Average

The below graph shows the average detached house price in the North Northamptonshire local authority area over time, sourced from the HPI. The two 18 SOUTHBROOK sales from July 2000 and March 2002 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 July 2000 sale was for 35% below the HPI. So the extrapolation line tracks at 35% below the HPI over time, until the March 2002 sale, where it falls to 36% below the HPI. The line then continues to track at 36% below the HPI.

What might 18 SOUTHBROOK be worth now?

18 SOUTHBROOK might now be worth an estimated £261,672.

This is based on house price inflation of 213.4%, between March 2002 and December 2024, for detached houses, in the North Northamptonshire local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 213.4% inflationary increase is applied to the most recent sale price for 18 SOUTHBROOK of £83,500 on 22nd March 2002. For the value to have increased from £83,500 to £261,672 over the 21 years and three months to December 2024, the following assumptions must hold true:

• The value of 18 SOUTHBROOK has moved in line with the HPI for detached houses in the North Northamptonshire local authority area.
• The March 2002 sale price of £83,500 represented a fair market value for the property.
• The size, condition, and specification of 18 SOUTHBROOK has not materially changed since March 2002.
