Could this be a means of writing off mortgages for DNC supporters, allowing them to funnel more cash back into the party?
Partly. I see it primarily as just another step to bankrupt the country and the world, creating a demand for a one world government and a super currency.
They just keep spending money where there is none. They either print it or expand credit to infinity. Either works toward their goal and together they accelerate the end.
They must get this all in place before someone with common sense gets in charge.

It may be via that method, it may be via other indirect methods, but it is surely the creation of a giant slush fund and/or patronage job bank in one form or another.
