1 RAFFIN CLOSE Price Paid vs. HPI Average

The below graph shows the average detached house price in the East Hertfordshire local authority area over time, sourced from the HPI. The two 1 RAFFIN CLOSE sales from July 2007 and September 2015 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 2007 sale was for 9% above the HPI. So the extrapolation line tracks at 9% above the HPI over time, until the September 2015 sale, where it rises to 31% above the HPI. The line then continues to track at 31% above the HPI.
