The Banks are convinced that they can keep many homeowners dipping into their savings, working 2 jobs, etc. to pay mortgages on the inflated bubble values. One way they hope to do this is by punishing owners wherever possible
After foreclosure, when they have to sell foreclosed REO property at real value, they refuse to sell that property back to the former owner or their family even if they can afford it. When non-profits make offers to by occupied foreclosed buildings, Wall St. banks will often insist on eviction first. They want to make the pain of foreclosure as unbearable as possible.
For this to be done by Wall St. banks that have been bailed out with trillions of dollars by taxpayers is unconscionable.
