17 FIRS AVENUE Price Paid vs. HPI Average

The below graph shows the average terraced house price in the Windsor and Maidenhead local authority area over time, sourced from the HPI. The three 17 FIRS AVENUE sales between December 1997 and July 2013 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 2011 sale was for 2% below the HPI. So the extrapolation line tracks at 2% below the HPI over time, until the July 2013 sale, where it falls to 5% below the HPI. The line then continues to track at 5% below the HPI.

What might 17 FIRS AVENUE be worth now?
