1 SIBLEY 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 four 1 SIBLEY AVENUE sales between August 1996 and October 2017 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 March 2012 sale was for 23% below the HPI. So the extrapolation line tracks at 23% below the HPI over time, until the October 2017 sale, where it falls to 29% below the HPI. The line then continues to track at 29% below the HPI.
