Health Professional Student Loans and all other private loans will allow you to borrow COA(Cost of Attendance) minus the Federal Aid.
Our COA for first year is 57,131 I believe (you can check this out under webstar after logging in click on Financial Aid and then My Overall Status of financial Aid). Federal Aid from Stafford is 38,500 (max). So, I think you can borrow upto 57,131 - 38,500 = 18631. I talked to a financial aid counselor a week ago about this myself.
BUT, I believe the disbursement of HPSL is based on need and the amount of funds the school recieves. So after you apply, THEY will determine how much to give you, it can be any amount (the counselor told me it depends on how many apply and how much funds they have to disburse among applicants). Also, they don't determine this until October...so we kind of have to wait on this loan. Hope that helps.
