It's usually wholesalers or flippers. They'll lowball the daylights out of you most of the time. They usually cold call people with multiple properties, people who have defaulted on their mortgage and homes where someone died (elderly). I know folks that have done it and you usually take a hit on the price but most of these guys can close FAST. For the folks I've known to do it, it was for their late parents homes that had tons of issues and they just wanted it gone.
