The below graph shows the average semi-detached house price in the Welwyn Hatfield local authority area over time, sourced from the HPI. The three 4 TREVENA GARDENS sales between August 2002 and September 2012 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 2011 sale was for 60% above the HPI. So the extrapolation line tracks at 60% above the HPI over time, until the September 2012 sale, where it rises to 69% above the HPI. The line then continues to track at 69% above the HPI.
4 TREVENA GARDENS might now be worth an estimated £884,893.
