Great point - most schools do not provide similar need based aid to transfer students. A few do. Case, Cornell and Umich seem to provide some need based aid to transfer students and provide instructions to transfer students on how to run their net price calculators.
It really is a waste to apply to schools that do not provide aid to transfer students, unless that student is able to pay full sticker.
And: FA policies change yearly. So student needs to double check aid policies/calculators again before applying. But even if the best aid packages go to freshman - at least that lets the applicant know if something will be out of range financially and can move on.
