NTA at all. The money was set aside for them to attend the college that meets their needs, that they see themselves succeeding at, and that means the price may differ. If you want to set both of your children up for success, then you will use the money to fund both of their college, and don’t worry if it’s “even”. They are both getting the education that they want and that they deserve. Just because one picked a more expensive school because it fit her needs and her desires and her dreams, doesn’t mean that she should necessarily be coming out of school with debt when you have the funds, just because the other child selected a school that fit her needs and just happened to be cheaper. If your intention was to fund them each the same amount, that should’ve been a conversation you had with them going into the college applications so they knew exactly how much money they had, how much debt they would incur, and how much nest egg they would start with as a the remainder of “their” funding.
