1 TRELAWNEY 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 1 TRELAWNEY AVENUE sales from May 2013 and March 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 May 2013 sale was for 56% below the HPI. So the extrapolation line tracks at 56% below the HPI over time, until the March 2017 sale, where it rises to 44% below the HPI. The line then continues to track at 44% below the HPI.
