As i know, $70000is used to cover tuition plus $4000 fellowship. And the total tuition for MS.MBA students is a little more than 80000USD.
Your background seems strong to get the scholarship. However, it depends on other factors including essay, interview and your career goals and your style. I strongly recommend you to have a try. good luck.

As i know, any loans BU offers to the international students require a us cosigner. I recommend you to try vanderbilt. It is a pretigious school in state. And it is generous to give full scholarship to cover both tuition and living expense. But, one of its shortfalls is its location.
I did not hear anyone in BU who got scholarship to cover both T & LE. But some one did in vanderbilt. I know one girl who apply for vanderbilt with the concentration on healthcare in the first ground got full scholarship.
