18 ROMAN WAY 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 three 18 ROMAN WAY sales between August 1997 and July 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 December 2004 sale was for 14% below the HPI. So the extrapolation line tracks at 14% below the HPI over time, until the July 2011 sale, where it falls to 17% below the HPI. The line then continues to track at 17% below the HPI.

What might 18 ROMAN WAY be worth now?
