21 CHAPMAN CLOSE Price Paid vs. HPI Average

The below graph shows the average detached house price in the Buckinghamshire local authority area over time, sourced from the HPI. The three 21 CHAPMAN CLOSE sales between June 2001 and September 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 April 2004 sale was for 42% below the HPI. So the extrapolation line tracks at 42% below the HPI over time, until the September 2011 sale, where it falls to 53% below the HPI. The line then continues to track at 53% below the HPI.

What might 21 CHAPMAN CLOSE be worth now?
