The below graph shows the average detached house price in the Buckinghamshire local authority area over time, sourced from the HPI. The two 42 BIRFIELD ROAD sales from November 2008 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 November 2008 sale was for 47% below the HPI. So the extrapolation line tracks at 47% below the HPI over time, until the July 2011 sale, which was also at 47% below the HPI.
42 BIRFIELD ROAD might now be worth an estimated £436,913.
