Investing with Student Loans

[Brad Koegel]

I am graduating graduate school for Physical Therapy in 4 months and will have a nice chunk of student loans (over 100k with interest included), but also have enough money currently saved to put down as a downpayment on a property or two.  I have been reading a lot of RE books and blogs, as well as listening to BP podcasts.  I would like to start investing in buy-and-hold real estate, and am toying with the idea of house hacking for my first investment, or potentially going the long-distance route if I can find a great deal.  

I understand from reading forums that investing can help to pay student loans quicker if done properly. Is there anyone who can give advice on the best way to go about doing this?  

In addition to this, would you choose the 110 month plan and pay a smaller total of student loans, or take the 300 month payment plan which will give smaller monthly payments, but will require a lot more interest on the loan debt to be paid back?

Any and all input is appreciated!
