16 WILLOW GROVE 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 16 WILLOW GROVE sales from September 1999 and April 2005 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 September 1999 sale was for 5% below the HPI. So the extrapolation line tracks at 5% below the HPI over time, until the April 2005 sale, where it falls to 21% below the HPI. The line then continues to track at 21% below the HPI.

What might 16 WILLOW GROVE be worth now?
