Is it a bad idea to invest a student loan?
There will be many who will judge your proposal on the idea that subsidized loans should be available to those who need them, and should not be used by others who are simply trying to profit from them. Each school has a pool of money available to offer for subsidized and unsubsidized loans. If they are giving you a subsidized loan, they cannot allocate it to someone else who needs it. Once you weigh the investment risks, I agree that it is analogous to investing rather than repaying your mortgage quickly. If you understand the risks, there's no reason why you shouldn't consider other options about what to do with the money. I am more risk averse, so I happen to prefer paying down the mortgage quickly after all other investment/savings goals have been met. Where you fit on that continuum will answer the question of whether or not it is a "bad idea".
