25 RAFFIN GREEN LANE 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 25 RAFFIN GREEN LANE sales from September 1999 and September 2003 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 September 1999 sale was for 31% below the HPI. So the extrapolation line tracks at 31% below the HPI over time, until the September 2003 sale, where it rises to 32% above the HPI. The line then continues to track at 32% above the HPI.
