41 PORTERS HILL 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 41 PORTERS HILL sales between March 1999 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 June 2004 sale was for 41% below the HPI. So the extrapolation line tracks at 41% below the HPI over time, until the September 2010 sale, where it falls to 48% below the HPI. The line then continues to track at 48% below the HPI.
