Interest rate-only adjustable mortgages may be making a comeback.  While recent market volatility has many investors on edge, the home loan business feels the need to perk up excitement in real estate.  As journalist Paul Sullivan points out in a 12/14/18 NYT column, this is not supposed to be a ‘back to the future’ moment.  Unlike a decade ago, loan applicants are to be thoroughly vetted to avoid a disastrous wave of nonperforming loans handed out to home buyers with insufficient resources.  OK, but… are the banks subsequently selling the loans to third parties?  Would be nice if they service them and live with the long-term consequences of their lending decisions.
