How old is your daughter? If you do this for your son, you are looking at his three remaining years in high school plus all four years he is in college, right? What about your daughter.
Seven plus years sounds like a very long time to work at a job you really can’t stand, if you can find something else.
Plus…your kids might not even get selected for tuition exchange. It’s not guaranteed.
I agree…is there anything else within your college that might be better work wise for you?
Can you put out applications elsewhere and see who bites?
Think about what your college budget will be annually. Make sure your kids know this when it comes time to apply. Hopefully they will get great grades and SAT or ACT scores which could net you a lower net cost than TE does.
Can you afford your instate public universities?? Looks like that might be Wisconsin…there are some less costly publics there.
How are you paying for your current freshman son who is already in college?
