I’m a 21-year-old college student majoring in physics and economics, I am the president of the Commercial Real Estate Club at my University, and am preparing to enter the investment banking industry after graduation.

It is simply a high-stakes gamble that you have to exit in 3 yrs or the bet won't pay off.

I bet you were ecstatic when that deal finally closed lol!

Does anybody know any banks that would be easy to open a business checking account without my partner's physical presence?  

Bet you don't refund them when they fail, do you?

How would you approach the seller to plant the idea of seller financing.Your best bet is to LBO the acquisition through packaging the business into a CDOYou'll take that CDO to private or commercial investors  

I'll bet my favorite Tulsa super-agent, @Tom O'Stasik, could answer your questions!

As soon as you start discussing your business practice and strategies with your customers (tenants), then all bets are off and you run the risk of Fair Housing violations. 

I bet realistically most people would stop there.

It seems like you enjoy being active and using your hands so maybe the BRRRR method (buy, rehab, rent, refinance, repeat) is your best bet as you could save some money and do plenty on your own, you could also do a live in flip potentially and sell it or rent it out later.
