The below graph shows the average detached house price in the West Northamptonshire local authority area over time, sourced from the HPI. The two 31B HARTWELL ROAD sales from September 2007 and February 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 September 2007 sale was for 69% above the HPI. So the extrapolation line tracks at 69% above the HPI over time, until the February 2019 sale, where it falls to 51% above the HPI. The line then continues to track at 51% above the HPI.
31B HARTWELL ROAD might now be worth an estimated £716,061.
This is based on house price inflation of 19.4%, between February 2019 and February 2025, 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 19.4% inflationary increase is applied to the most recent sale price for 31B HARTWELL ROAD of £599,950 on 14th February 2019. For the value to have increased from £599,950 to £716,061 over the six years to February 2025, the following assumptions must hold true:
