8 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 two 8 PORTERS HILL sales from January 1999 and June 2001 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 January 1999 sale was for 58% below the HPI. So the extrapolation line tracks at 58% below the HPI over time, until the June 2001 sale, where it falls to 59% below the HPI. The line then continues to track at 59% below the HPI.
