The below graph shows the average detached house price in the St Albans local authority area over time, sourced from the HPI. The two 41 CLAYGATE AVENUE sales from September 1999 and October 2011 have been plotted on the graph.

For example, the September 1999 sale was for 5% above the HPI. So the extrapolation line tracks at 5% above the HPI over time, until the October 2011 sale, where it rises to 46% above the HPI.
