Thanks. I have the money, I want points and for him to deduct the 2 that are currently accruing interest (unsubsidized). The subsidized ones have a 6 month grace period and technically could be discharged with public service but I hear that's impossible to actually get. And he'll be left with about 4k+ what he cannot save from this summer or pay off as he goes.
Yup - as stated above, if you pay the minimums on the loans, then any extra you want to pay you can designate to specific loans (sounds like in your case it would make sense to designate any extra amounts to the unsubsidized ones) - but you generally have to call each time to the servicer to specify that. And if you're paying on behalf of your grandkid, only they get to deduct the student loan interest (and there are income rules, once he starts earning a certain amount income, or if he files separately from a spouse, then he's not eligible to deduct student loan interest anymore) - either way, you don't get to deduct the interest on his loans even if you're the one paying them off. Also to your comment about public service loan forgiveness for your grandkid - it's not worth it unless he will have well over $100k in loans which it doesn't sound like he will. It takes 10 years to qualify so if he only has say, $40k in loans, he's much better off just paying them off as quickly as he can. Now, if he's making very little in a public service job (for example, teaching music at a public elementary school or something) and there is no way he can pay his loans off within 10 years, then it is what it is, he can get into a repayment plan eligible for loan forgiveness that only makes him pay 10% of his discretionary income and even though his balance will balloon (because generally, on a low salary, 10% of your discretionary income means you're just paying off a little interest each month and not at all touching the principal so your balance keeps growing), if he stays in public service for 10 years then it can be forgiven, but for most people, it's not worth it to let a small balance balloon due to unpaid principal over 10 years just to qualify for loan forgiveness because during those 10 years you have to be making payments every month. And from a career standpoint, if he lets his balance balloon, then he might feel trapped in a public service job for 10 years just because if he were to get out before forgiveness, then he'll have to pay back way more than he ever would have if he had never tried for forgiveness.
This is why loan forgiveness is a tough situation - even if one is able to navigate the rules to qualify for it, there are so many non-financial decisions to take into account because it honestly doesn't make sense for everyone even though in theory it sounds like free money - do you want to be trapped in public service for 10 years (in some fields like mine, this is not a problem, in others, it can really limit your career choices), if you started out in the private sector and have already made a good amount of payments before moving to public service - it might not be worth it to try and qualify in 10 years if you're halfway done to paying off your loans, etc.
