Oh and I just checked the rates, so is AU mortgage rates 6.8% with the term 30 years, so you telling me the buyer ends up paying 13 million in the end? Good grief

This was likely either a Developer who will put 4 townhouses on the block and sell them for $2M a pop or a Chinese buyer who paid cash.
Not even the top 1% can afford a $30k per month mortgage. 
30 year fixed rate mortgages are not a thing outside of the US
Not sure about fixed rates, but there are 30 year mortgages in EU countries
Those are definitely not fixed rate mortgages
