Great tip, @guifig! I’m sure this can come in handy for many 
If just like to add that Interactive Brokers has a similar offering open to both US and non-US residents.
Since many already invest with them and their fees are incredibly low you should check if they can offer you what you need. I don’t recall the specifics, but I believe you may not be able to take out as big of a loan (as a % of assets) as you could with the banks Gui mentioned.
