12 SCHOOL 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 two 12 SCHOOL LANE sales from November 2008 and January 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 November 2008 sale was for 94% above the HPI. So the extrapolation line tracks at 94% above the HPI over time, until the January 2019 sale, where it rises to 95% above the HPI. The line then continues to track at 95% above the HPI.
