There have long been obstacles to investing to US SFH rentals.

They are an amazing asset class, but hard to bulk buy in 20-50 million chunks like stocks and bonds, buy in specific amounts, buy for foreigners, etc.

Hedge funds and SFH rental REITs are working to fix this issue.

Think of all the German insurance companies and pension funds buying bunds that pay only 0.8% now. Their excess savings are better invested here. Instead of losing about 10% the past year as yields rose from negative to .8, they could have gained 30% appreciation plus another 10% on the dollar rising.
