To answer the question about what will the banksters do, we must look to what the WEF says the goals are.

To own nothing.

So, the person in their system, will work, and part of their "payment" will be for their home.
In this system, the bank gets a mortgage (the person pays for life) that is always paid.

The person thinks they get a free house.
Everyone's happy?

The banksters get to leach off society, without having to get their hands dirty.
The person gets to live in as cheap of a place as law will allow... for free!

So, the answer is, is that particular bank in with the WEF?
Most small banks aren't, and they will be destroyed in this house bubble destruction.
Blackrock and stone will buy up all the houses that they can.
(and supposedly rent them)
BofA and all the other bigs will absorb all that they can, taking in all the mortgages.

BTW, many mortgages do not include a clause that the buyer gets the house deed at the end of the mortgage.

This is their goal and their plan.
It just will not work.

Just like the prison camps all over America will not go according to plan.
