Long story short, we made it clear to our 3 wonderful daughters that DW and I were able and willing to fund each of their 4-year undergraduate degrees, the equivalent $ of 4- years tuition, books and fees, at the nearby major state university (Go Buckeyes!). There was no need to either go out of state or live on campus since we are approximately 20 minutes from main campus. Want to live on campus? That's entirely optional and on them. This was back in the early 2000's, with tuition running approx $8k per year, and room and board about the same...
Two went further for Masters (education)and one to a doctorate (DPT). All are very successful in their fields, and student loans are practically paid off.
Neither we nor they went broke in the process. We think having some $skin in the game encouraged great academic achievement and actually more appreciation of our "gifts" than had we simply given them all the money up front.
