Much like the weasel-word "affordability" (which means better access to credit, and not cheaper prices) "home ownership" means "mortgaged, bank-owned properties". Both terms mean debt slavery and a preservation of the status quo (ie: property owners stay rich. buyers, mortgagers and prospective buyers remain poor).
What is needed is cheaper housing.
Not "affordability" or easier-to-access debt.
The way to get cheaper housing is to destroy housing as an investment class. And the way you do that is by taxing 2nd and 3rd properties at increasingly higher rates.
