A guaranteed acceptance program (GAP) at an affordable state school is great way to keep costs down.
For private schools, maybe take a look into Seton Hall’s new-ish BS/MD. They tried to change how these programs work. You are considered for undergrad merit like any BS student and SHU gives a lot of merit (like $20-30k) so that can bring the cost way down for a private school (still not Florida in-state of course). They are affiliated with Hackensack Meridian medical school and Hackensack is a top NY area hospital. As a student in the program, you are guaranteed an interview (only) with the med school and they have a certain number of slots. Not guaranteed acceptance, but you get the interview.
