7 CLAYGATE 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 7 CLAYGATE AVENUE sales from December 2005 and March 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 December 2005 sale was for 25% above the HPI. So the extrapolation line tracks at 25% above the HPI over time, until the March 2012 sale, where it rises to 41% above the HPI. The line then continues to track at 41% above the HPI.
