3 ROTHAMSTED AVENUE Price Paid vs. HPI Average

The below graph shows the average detached house price in the St Albans local authority area over time, sourced from the HPI. The two 3 ROTHAMSTED AVENUE sales from October 1998 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 October 1998 sale was for 60% above the HPI. So the extrapolation line tracks at 60% above the HPI over time, until the September 2015 sale, where it rises to 105% above the HPI. The line then continues to track at 105% above the HPI.
