I agree transfer merit aid will generally be less (need based aid should be the same especially at the schools that meet full aid or come close), but it’s not clear you qualify for need based aid), and many LACs don’t even take many transfers because well, they’re small.
If she takes a gap year, realize she will be applying in a matter of months, and nothing will have happened that is likely to change the results at the schools where she wasn’t accepted. I agree with the other less selective LACs listed above, if your D does take a gap year.
Also do you know if Rochester allows those who take a gap year to apply to other schools…most selective schools do not allow that)…has your D asked them?
