My sister inlaw and her hubby are one of them .. they have 3 mortgages at the moment .. it's a long story
My daughter, who's a class mother, tells me that when they're collecting for a teacher's gift around Christmas, the parents they have the hardest time getting money out of is the people living in the neighborhoods where the houses go for more than 750k. I know for a fact many of those folks are living paycheck to paycheck.
