That is a tough decision. For my family, we chose the most affordable option. Although maybe I would have fit in socially more at Brown, it was really a financial stretch for us (and Johns Hopkins was just out of the park). I am fortunate to have the most affordable option be in a location (Cambridge) that has many job/internship opportunities.
I have no experience with finances from an adult standpoint, but I think you should choose out of the schools that are the most affordable out of all the options (even if they are a little stretchy). Then crunch the numbers and see if after the 5500 federal loans, if the out of pocket cost is doable or not. That's what really helped my family. But we also didn't forget that although maybe my mom could have paid the remaining cost with no/minimal loans, there would still be $20,000+ of loans when I graduate that I will have to pay back. And my mom and I want me to try and live on my own when I graduate from college/graduate school, and that much money in debt would be difficult while straddling living costs.
Good luck! Hope everything works out and let us know what you ultimately decide.
