3 KEYSTONE 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 five 3 KEYSTONE sales between October 1999 and May 2020 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 July 2012 sale was for 12% above the HPI. So the extrapolation line tracks at 12% above the HPI over time, until the May 2020 sale, where it falls to 5% above the HPI. The line then continues to track at 5% above the HPI.
