12 SCHOOL LANE 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 12 SCHOOL LANE sales from November 2008 and January 2019 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 2008 sale was for 94% above the HPI. So the extrapolation line tracks at 94% above the HPI over time, until the January 2019 sale, where it rises to 95% above the HPI. The line then continues to track at 95% above the HPI.

What might 12 SCHOOL LANE be worth now?

12 SCHOOL LANE might now be worth an estimated £794,988.

This is based on house price inflation of 23.3%, between January 2019 and February 2025, 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 23.3% inflationary increase is applied to the most recent sale price for 12 SCHOOL LANE of £645,000 on 3rd January 2019. For the value to have increased from £645,000 to £794,988 over the five years and eleven months to February 2025, the following assumptions must hold true:

• The value of 12 SCHOOL LANE has moved in line with the HPI for detached houses in the North Northamptonshire local authority area.
• The January 2019 sale price of £645,000 represented a fair market value for the property.
• The size, condition, and specification of 12 SCHOOL LANE has not materially changed since January 2019.
