Man. I wish we had CC managing the national budget.
I think, OP, that you are getting a lot of pushback because your dreams are simply larger than your budget. Even if your parents were willing to co-sign for massive debt, they would be unwise and you would be unreasonable for asking them to do it. The advice to make a spreadsheet is very good rather than simple pro:con lists.
Bottom line for Alabama, your best case scenario financially, in rough numbers:
Total cost of tuition, room, board, transportation (flying 3 times a year): $187,772
Financial aid from UA: -$80,000
Parental Contribution: $-20,000
Student Loans: ~22,000
Net result: $65,000 shortfall.
In other words, your best choice is unaffordable. Even if your parents were willing to take on that debt, they should not.
UA offers generous credit for AP’s so you might be able to finish in 3 years which would tread against the “time of your life” ideal but would lessen the blow financially. Cost of $140,829 - 60K aid - 20K parents - 15.5K loans = deficit of about $50,000 for 3 years. If you did work study and worked in the summers maybe you could whittle $10K off of that leaving your parents liable for $40,000.
You don’t mention your parents income (which is fine). Perhaps they make enough that they could cut back on spending and loan you the money personally e.g. 20K gift, 40K loan. That would make UA in three years barely affordable.
You might not like it, but money will make the choice for you. NYU is an impossibility. Even if you went there your lifestyle would not lend itself to the time of your life. And winters in Pittsburgh vs Alabama? Unfortunately you have crafted a dilemma for yourself with your college choices. Sounds like Michigan or Michigan State would be the most likely choices. I understand the urge to move on - but that is what graduate school and work are for. At this point in life, you need to be willing to go where reality takes you until you can create your own options.
