In January 2022, the Fed owned 24% of residential mortgages.
Meanwhile, a bunch of conservatives predicted that Blackrock would gobble up all real estate in the US.
In reality, it's the US government that's been gobbling up real estate (the Fed is controlled by Congress).
When residential foreclosures start ramping up, the Fed will ask Congress, "should we evict the people who can't pay anymore, or should we just let them live in government-owned houses for a while?"
