"Just what happens when our undocumented friends end up underwater on their mortgage and flee back to buena Mexico? I'm betting Wells Fargo won't be stuck with the tab."
What tab? - this is a home loan, secured by a house. Wells Fargo simply forcloses, takes all the equity for themselves, and resells. A nice scam.
However, WF is scum for doing this - it's like saying "Hey, it's not my job to help put my neighbor's house fire out - that's the job of the city fire department".
Maybe they are counting on a huge populist uprising where all the illegals are thrown out - then they will own all the houses the illegals used to live in?
