what happens if all the bank owned properties. keep them and rent them out.?

will all real estate in america soon be owned by banks and we all become slaves to the big banks of the world?

What on earth are you talking about?!?!?! Why would all property become owned by the banks? This makes no sense at all. Many of us own our own homes free and clear.
The bank only takes houses when people stop paying their mortgages. Many people are responsible and either own their homes outright or did not buy something they can not afford. When you buy a $400,000 home and only make $20,000 a year expect the bank to take it away when you can not make your mortgage payment,
no, cause the banks will lose too much money. if people can't afford the mortgage how can they pay the same amount in rent? also rents would go down and prices of real estate will go up which is not efficient equity management on the bank's part.
What in the hell are you talking about?
They sell them usually. I've never heard of them renting them out??
