I think we also have to remember that student loan debt is not bankruptable. It will never go away until it is paid off. There was a mention of Suze Orman in a PP and I have seen one of her episodes where a man was semi-suicidal and crying because he could not get out of his student loan debt and couldn't afford to pay it. He was in his 40's so I don't know if he could defer it.
To answer Honey693, I am in theory against mortgages but do have one because I am also against us being homeless. haha. But then again a loan for a house guarantees a house. Loan for school doesn't guarantee anything.
