Where you live shouldn't matter so much as what schools you've applied to and how late in the season you filled out your FAFSA.
The best time to fill out the FAFSA is as soon as you've filled out your federal income taxes for the previous year or better yet, as close to the beginning of the year as possible. That's because you want to be one of the first in line while the schools still have most of their funds available for distribution.
Unfortunatley, at this late date, most schools have already given away most of their funding. Don't worry though, there's always something left.
Now that you've filled out the FAFSA and it's being processed, I would give it a couple of days and then call the school to confirm that they've received it in their systems and after that, there's not much you can do but wait. You will recieve a letter from FAFSA telling you that your application has been processed or asking for more information if needed. Just fill that out and return it.
Then you'll start receiving letters from your schools (if you've been accepted) detailing how much money in loans and grants that you'll be provided coming from both the federal government and the school. With that information, you'll be able to make up your mind which school you can afford to go to.
The biggest difference between you (as an adult single mom) and most of the other population (of young first time college students) is because you may actually have an income to report to FAFSA rather than your parent's income, you'll more than likely get offered more loans than grants. In that case, just be careful to to know the difference between subsidized and unsubsidized loans.
Here's a quick breakdown:
Subsidized loans are awarded based on financial need and you will not be charged interest while you're still in school and during any periods of deferment.
Unsubsidized loans are not awarded based on financial need. Any student can take out this loan to help pay for school. You will begin paying interest from the time the loan is disbursed until it's paid in full.
Anyway, that's all I can think of. Hope it helps.
