TREWEN 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 TREWEN sales from December 2001 and February 2018 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 December 2001 sale was for 206% above the HPI. So the extrapolation line tracks at 206% above the HPI over time, until the February 2018 sale, where it falls to 174% above the HPI. The line then continues to track at 174% above the HPI.
