17 MAIN ROAD 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 17 MAIN ROAD sales from March 2003 and October 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 March 2003 sale was for 84% above the HPI. So the extrapolation line tracks at 84% above the HPI over time, until the October 2019 sale, where it falls to 61% above the HPI. The line then continues to track at 61% above the HPI.

What might 17 MAIN ROAD be worth now?

This is based on house price inflation of 24.5%, between October 2019 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 24.5% inflationary increase is applied to the most recent sale price for 17 MAIN ROAD of £530,000 on 24th October 2019. For the value to have increased from £530,000 to £659,917 over the four years and ten months to December 2024, the following assumptions must hold true:
