100 ECTON 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 four 100 ECTON LANE sales between June 1999 and June 2013 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 August 2003 sale was for 69% above the HPI. So the extrapolation line tracks at 69% above the HPI over time, until the June 2013 sale, where it rises to 104% above the HPI. The line then continues to track at 104% above the HPI.

What might 100 ECTON LANE be worth now?

This is based on house price inflation of 92.1%, between June 2013 and March 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 92.1% inflationary increase is applied to the most recent sale price for 100 ECTON LANE of £435,000 on 20th June 2013. For the value to have increased from £435,000 to £835,533 over the twelve years and three months to March 2025, the following assumptions must hold true:

• The value of 100 ECTON LANE has moved in line with the HPI for detached houses in the North Northamptonshire local authority area.
• The June 2013 sale price of £435,000 represented a fair market value for the property.
