55 SCHOOL LANE Price Paid vs. HPI Average

The below graph shows the average detached house price in the West Northamptonshire local authority area over time, sourced from the HPI. The two 55 SCHOOL LANE sales from March 2012 and July 2014 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 March 2012 sale was for 99% above the HPI. So the extrapolation line tracks at 99% above the HPI over time, until the July 2014 sale, where it falls to 75% above the HPI. The line then continues to track at 75% above the HPI.

What might 55 SCHOOL LANE be worth now?

This is based on house price inflation of 54.5%, between July 2014 and December 2024, for 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 54.5% inflationary increase is applied to the most recent sale price for 55 SCHOOL LANE of £532,000 on 9th July 2014. For the value to have increased from £532,000 to £821,929 over the nine years and seven months to December 2024, the following assumptions must hold true:
