Bibbs: At your income level, fin aid will just be loan offers. The parent contribution portion will be high.
Any 529 is considered liquid cash. Your retirement funds are noted, but are not a factor in the fin aid calc. Same with home ownership and business assets.
They will tell you you don’t have to sell your house, nor dip into retirement to pay for college.
Flu is spot on regarding the 529 advise.
Of course at private univ, residency doesn’t matter.
The emancipated minor angle is legit and will qualify kid for more grant money as he has no income nor assets. I don’t agree on doing this just to save a buck.
