I do not know right now if there is age discrimination in student loan availability but if not, what would stop someone who is in their 30s or 40s from taking out student loans and investing that money instead of using it for books and housing, then getting the debt cancelled if the current proposals happen?
Can you qualify for funds for room and board if you are older? It would be an interesting way to reduce expenses and some of the college towns are in pretty interesting locations.
Well, there are several problems with your plan.
First, you'd have to actually be going to college to take out student loans. Some (most?) loans and grants require you to attend full time or at least half time. Maybe that's what you want to do with your time, maybe not.
Second, if you invest that money instead of using it for books and housing, then you'd either (a) have to use other money of your own to pay for books and housing, thus creating no real net benefit to your scheme, or (b) not buy the books and housing, therefore committing loan fraud and face prison, or (c) take out loans in excess of books and housing, the excess of which is likely to be considered taxable income (google "taxable scholarships and grants" and read a few articles).
Third, student loans have interest and origination fees, which would set you back if the forgiveness doesn't happen.
Fourth, there's a possibility that forgiven student loan principal would be considered taxable income in the year in which forgiveness happens.
Finally, you can legally only borrow for room and board for "COA" - cost of attendance. Cost of attendance is either your actual cost if you're living on campus in a dorm, or a budget number calculated for you by the school. This number may be higher or lower than the published cost of room and board depending on your living situation. My son's COA is quite low because there is a category at his school called "living with parents". Borrowing more would either create loan fraud or taxable income, depending on the circumstances.
Props for thinking outside the box, though!
