I have 3 daughters, 2 of college age and one graduating next year from high school, and college is expensive AF. But you know what? If they want to take a "gap year", more power to them! I did, in between the AA degree and transferring to a 4 year college. It's been a looooong year -- I never did go back. But I encourage them to do what they feel is best for them.
So long as they pay for it.
The agreement I have with them is this: I have been paying into college funds for over two decades now. So long as they take a full load and get good grades, I'll also pay for their apartment and their utilities, and they get an allowance for groceries and whatnot. Essentially, I'm their employer and I'm paying them to go to school and get good grades. Anything less and they need to start supporting themselves.
So if they want to take a gap year, they better get a gap job, because they are not partying on my dime. Not after I socked all that money away to pay for their college. Stick to my plan or pay for your own plan.
