This has been an interesting thread. Here in Florida, the e-buyers have been very active. I'd buy from them, even after reading what I've read here, but it will be on much less forgiving terms than I would from an individual owner of the property.
There is so much shady activity going on in RE this time around. We hit a "middle ground" somewhere between 2015 and 2019, where buyers and sellers could expect a typical transaction. Less homes underwater, meant fairly normal closing process for sellers. Underwriting on loans had absorbed much of the death of 2006-2012 by then. Credit scores for a buyer who had a bad experience in that earlier timeframe, had improved. Flash-forward to 2020, and the mania began.
All of this, ALL OF IT, is blood on the hands of the federal reserve, for keeping rates too low, for too long. Sure, we fixed the problem with liar loans, after the meltdown in 2008. But a new one has emerged, and it's predatory, deep pocketed e-buyers, like OpenDoor, Zillow (until they nixed it late in '21), and a few others. And where do they get the money for these purchases? Bond sales. "Investment Grade" bond sales. Trouble is ahead.
