9 CHALFONTS Price Paid vs. HPI Average

The below graph shows the average detached house price in the York local authority area over time, sourced from the HPI. The two 9 CHALFONTS sales from November 1996 and November 2001 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 1996 sale was for 18% above the HPI. So the extrapolation line tracks at 18% above the HPI over time, until the November 2001 sale, where it falls to 10% above the HPI. The line then continues to track at 10% above the HPI.
