true, but i really don't intend to defer payments. Because unless they are the "subsidized" version of the Stafford loan, the "Unsubsidized" that is, interest will accrue over the time in graduate school and you might tend up paying back twice as much as you actually borrowed. I plan to pay a little bit each month while in grad school and hopefully get rid of it. I don't have as much as some people have, but you can get up to (not guaranteed) $8500/academic year in subsidized loan. It would be smart to take that loan out (whether you need it or not) and use that money to pay off "Unsubsidized" loans from undergraduate if you happen to have some. Essentially you switching 8500 of Unsubsidized loans to subsidized loans. that way you can defer it through grad school and not pay a monthly bill and don't have to worry about it accruing interest over 5 years or so. Again its only 8500, so it most likely only take care of only a portion of unsubsidized loan, but at least its something. This is something no one will tell you but you have to think of on your own.
Plus with inflation, you'll pay back the loans (5 years from now) with dollars worth a lot less. Economics I think is just as fundamental as physics.
