Profits from property sales are often tax as CGT. It's only a select few jurisdictions that don't tax property sales, often with both CGTs and stamp duties.
The difference in how their taxed in the US is certainly not standard globally, nor is it likely to be optimal.
OK I did not know this about the U.S, having never owned property there.
Actually seems a bit weird to find a tax situation in the U.S that seems less beneficial to the person paying the tax than many other countries.
