The below graph shows the average semi-detached house price in the North Northamptonshire local authority area over time, sourced from the HPI.

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 January 2019 sale was for 6% below the HPI. So the extrapolation line tracks at 6% below the HPI over time, until the July 2026 sale, where it rises to 2% above the HPI.
