86 COWPER ROAD 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 four 86 COWPER ROAD sales between September 1996 and September 2010 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 April 2004 sale was for 15% below the HPI. So the extrapolation line tracks at 15% below the HPI over time, until the September 2010 sale, where it falls to 19% below the HPI. The line then continues to track at 19% below the HPI.
