Sadly, since living conditions in the US are deteriorating, dangerous, and unattractive, your investment... is the same: people won't pay a fortune in rent for the privilege of being mugged in their sleep (exaggerating for effect).
And again I'm not even saying that it's actually like that there, but that's how we seem to perceive the US from abroad: we're not jumping on it, it's scary and strange, and it doesn't bring as much yield as safer, less unstable countries. I'd rather buy a losing property in Japan, making up for the value loss (automatic there due to earthquake damages) in stable unchanging rent, with an asset I can safely visit when needed, or at least just access when needing to sell.
If you just want real estate exposure you make a REIT mix and pray the Gods you won't be scammed, from a few click in your broker's app. When you buy a real thing, you don't touch the US.
