Living expenses, travel expenses, book expenses, and even the one time expense of a $2000 laptop computer are included in the cost assessment that GradPlus covers. You are getting yourself in serious *&^% if you try to take out a loan even bigger than the maximum amount GradPlus allows for and I really doubt any lender will be willing to take on that kind of risk and they certainly wouldn't be willing to do a deferment because it is obviously not for school.
