21 BLACKSMITHS HILL 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 two 21 BLACKSMITHS HILL sales from May 2003 and March 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 May 2003 sale was for 73% above the HPI. So the extrapolation line tracks at 73% above the HPI over time, until the March 2020 sale, where it rises to 95% above the HPI.
