OP has not clarified. I took her initial comment to mean FAFSA EFC which of course does not count home equity @mom2collegekids. I agree with everyone that when only referring to FAFSA, the two kids should be the same barring some windfall that only one received from work or a relative.
I was responding to Thumper1 and the comment about UNC and UVA meeting full need and UMich trying. Admittedly off topic but again in response to twogirls saying her kid was at an OOS Public that meets full needs.
