You can get income based deferrals, or reductions in payments. You have to prove your income and debt. Call your loan provider, and they can provide you with the options. Depending on what type of a loan you have, it may be a one time thing.
That said, what are your other options? It sucks that you have that payment with your income, for sure. But can you get a cheaper car? Do you have a relative with a beater car that you can buy? Can you move closer to work? Can you live somewhere with cheaper rent? I'd suggest other options other than trying to lower your repayment. It will be a long time to pay them off, but with interest riding, you could make it alot longer if you choose to reduce your payments.
I understand it's not uncommon nowdays for people to come out of college with student loan debt and lower incomes, but how did that happen to you? What was your major? Why the high student loans?
I currently pay $495 for rent (studio) and live about 5 blocks from work in Des Moines; I didn't get this job until it was too late to get a roommate to split rent for a bigger place. That's something I'm hoping to change next year, since I've got several buddies from high school who are now working here in DM, but already had living arrangements taken care of by the time I knew I'd be here, too.
I need something with pretty low miles because I'm going to be putting a lot on for work driving to games all over the place. And I absolutely refuse to get something that isn't certified, because I've had horrendous luck with vehicles thus far (I'm currently on my fourth in 7 years). I want something I know I can depend on.
As far as supplemental income, I'm probably going to be picking up a second job for a couple nights a week, and I also want to find time to get tested for plasma donation. That helped me get through my last couple years of school when I was making about $75 a month working for the student paper. I've just struggled to find a 4-5 hour window to get tested (I know from experience that it's wise to plan for that long on your first visit).
I'd definitely love to have a better paying job, but I had similar offers from every opportunity that popped up. I don't currently get health benefits, but I have insurance through the university that's good until next summer. But if benefits won't be picked up by the time my current insurance expires, I'll be job shopping pretty hard. However, this is largely a startup operation (new ownership group took over last year) and my job is basically to help grow this from what it's been, not just maintain it. We also plan on moving to a digital magazine for our monthly content and then print a few special issues (like our football preview). That cuts out a ton in printing expenses, which could mean a little more money for employees. Bottom line, I never planned to stay here for more than 2-3 years before moving on to something else, hopefully at either the Register or Gazette.
