17 BIRCHALL WOOD 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 17 BIRCHALL WOOD sales from June 1997 and October 2011 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 June 1997 sale was for 44% below the HPI. So the extrapolation line tracks at 44% below the HPI over time, until the October 2011 sale, where it rises to 42% below the HPI.
