When I fill out the FAFSA they don't care about money you have in retirement, what they care about is current income for the household. So if you save for your own retirement, in qualified retirement accounts, that money is not touchable as to college money and cannot be considered.
However, the income threshold is rather low in order to get grants for school. My children do not qualify for grants, only loans, so they're going to community college if they don't get a scholarship. I will discourage them from getting loans and help where I can,but I won't be short changing my retirement fund while doing it either.
They can live at home, free room, free rent, go to local community college, which is not expensive at all and they have monthly payment plans

. If they want more than that they better get great grades and a scholarship. My oldest daughter did get a few scholarships, knowing that mom and dad will help with community college. I believe we should pay 2/3 and the student should pay 1/3 of their college tuition and books. This teaches responsibility, appreciation and that money doesn't grow on trees.
My 21 year old daughter is a Nurse Technician and is putting herself through school now because she had dropped out previously after getting herself in a bit of trouble with credit cards. She went away to college due to the scholarships, but apparently they bombarded her with credit offers, and being a starving student she finally caved. Dad and I sent her exactly the amount of money we would have, had she gone to community college because that is all we should do (in our opinion). But, she has grown up a lot and is doing well.
Younger daughters learned from watching oldest daughter, they are frugal with money, and hate credit cards, and WANT to go to community college and live at home for free. haha
