Howard won’t supply much FinAid. Not 100% certain, but you should plan on paying a minimum of $30K-35K/yr out of pocket if you plan to transfer to Howard. It would be unusual for a transfer to get much FinAid there.
Hampton will be slightly less costly out-of-pocket and is a fantastic university, too.
Emory, USC and Vanderbilt are full-need universities, so all meet your financial need as they determine your need. On the other hand, each of these are going to be much more difficult to be admitted into.
If these are your most desired choices, you should most definitely apply. However, if you must transfer out of your current college, be sure you include other schools where it is more likely you’ll be admitted AND are affordable to you.
Good luck!
