40 LLANDENNIS AVENUE Price Paid vs. HPI Average

The below graph shows the average detached house price in the Cardiff local authority area over time, sourced from the HPI. The two 40 LLANDENNIS AVENUE sales from September 1998 and May 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 September 1998 sale was for 57% above the HPI. So the extrapolation line tracks at 57% above the HPI over time, until the May 2001 sale, where it rises to 152% above the HPI. The line then continues to track at 152% above the HPI.
