It's not about foreclosure sales. It's about the desperation, the ruthlessness, the intense pressure, the instant legal armament. Some other commenter here mentioned 3 day eviction notices (when renting) are a thing. Come on...
You obviously read other comments, so you'd know that people talk about foreclosures taking 6 months. That's far from "instant legal armament". I wouldn't even call it ruthless.
The 3-day eviction notices on renting are a red herring. We're not talking about renting from an owner, we're talking about foreclosures.
