I have leftover 529 funds and want to use them for my brother's two kids. My brother has zero EFC so I don't want to negatively impact his financial aid. The kids are two years apart in age. I'm thinking of waiting until the last year and a half of college to use the 529 funds for the older child, so I won't impact the financial aid. And then do the same thing for the younger child. But will the use of the funds for the older child (when the younger child is in college), affect the financial aid for the younger child?
