There were millions and millions laid off or wiped out in the financial collapse. Many of them if not most were good Americans that did nothing to deserve the fate that was handed them.
After some years of unemployment, a person becomes de facto unemployable. This is why the Obama unemployment figures were a joke because the workforce participation rate became so low that the employment calculations became a farce.
The Trump Administration is highly supportive of putting good people back to work. After a year or so of solid employment, those people should be able to get back into a mortgage.
The mortgage crisis left millions stranded in default of mortgages. The bank owns the property in most of those cases of default. These homes sit empty and cost a lot to maintain. In many cases, there is no maintenance. The properties are a blight on the community.
The effort on the part of GSEs Fannie, Freddie, to help find employment for those that were thrown out of the Obama economy is a good one. If such persons can reestablish credit, they can possibly qualify for mortgages. The outcome can be a win-win fr all.
