18 GRASMERE 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 18 GRASMERE AVENUE sales from August 2007 and September 2012 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 August 2007 sale was for 46% above the HPI. So the extrapolation line tracks at 46% above the HPI over time, until the September 2012 sale, where it rises to 77% above the HPI. The line then continues to track at 77% above the HPI.
