You are 99% certain to get no grant money but you will get all the loan money you want (up to $110k a year) as long as you are a US citizen and don't have a past drug charge.
$110k is this year, but that will go up about 5% next school year based on annual tuition increase. So $115k + market rate interest from private lender if you are non-citizen.
1st yr will probably set you back at least $120k, well on your way to half-a-mill for all 4 years.
