40 NORTHUMBERLAND AVENUE 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 two 40 NORTHUMBERLAND AVENUE sales from July 2012 and August 2014 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 July 2012 sale was for 29% below the HPI. So the extrapolation line tracks at 29% below the HPI over time, until the August 2014 sale, where it rises to 4% above the HPI. The line then continues to track at 4% above the HPI.
