15 ROSEDALE 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 ROSEDALE sales from October 1997 and July 2009 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 October 1997 sale was for 45% below the HPI. So the extrapolation line tracks at 45% below the HPI over time, until the July 2009 sale, where it rises to 40% below the HPI. The line then continues to track at 40% below the HPI.
