23 ROSEMARY DRIVE 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 23 ROSEMARY DRIVE sales from June 2005 and December 2014 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 June 2005 sale was for 24% above the HPI. So the extrapolation line tracks at 24% above the HPI over time, until the December 2014 sale, where it falls to 4% below the HPI. The line then continues to track at 4% below the HPI.
