Help Me Decide! Grinnell vs Private Local College

Hello,
I’m currently on a gap year studying a foreign language on the NSLY-Y program.
I’m deciding between Grinnell College and a local private university. I’m debt adverse and wondering if Grinnell is worth the extra cost. Grinnell would cost me $18,100 a year and the local university would be around $10,000. I will work during the summer and on breaks at my family’s business where I make $15 an hour.
I plan to major in computer science and continue studying a critical language.
Stats:
30 ACT
4.0 GPA

How much of the extra cost for Grinnell would be debt?

In terms of CS and the language, you can compare courses offered, but since you did not name the non-Grinnell college or the language, others cannot help you in this respect.

Around $50,000 would be debt at Grinnell. I don’t want to give out too much personal information but only Grinnell offers my target language.

^That’s about $20k more (in loans) than you can take out on your own. Are your parents onboard with taking out loans?
