15 CARBONE HILL Price Paid vs. HPI Average

The below graph shows the average detached house price in the Welwyn Hatfield local authority area over time, sourced from the HPI. The two 15 CARBONE HILL sales from July 2002 and July 2010 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 2002 sale was for 246% above the HPI. So the extrapolation line tracks at 246% above the HPI over time, until the July 2010 sale, where it falls to 181% above the HPI. The line then continues to track at 181% above the HPI.
