20 PERCY ROAD Price Paid vs. HPI Average

The below graph shows the average terraced house price in the Watford local authority area over time, sourced from the HPI. The three 20 PERCY ROAD sales between July 1997 and December 2007 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 March 1998 sale was for 3% below the HPI. So the extrapolation line tracks at 3% below the HPI over time, until the December 2007 sale, where it rises to 3% above the HPI. The line then continues to track at 3% above the HPI.

What might 20 PERCY ROAD be worth now?
