Hey Zach,
First off, hello from St. Augustine, and welcome to Bigger Pockets. There's a lot of information here...I've barely scratched the surface myself.
There seem to be a couple schools of thought as far as student loans and investing. One camp will make the argument to save your money and invest as long as you can get higher returns on that money. Others will encourage a more conservative approach that focuses on paying down the debt as quickly as possible. Then there are some hybrid thoughts, like Ian's above, that mesh the two....he seem pretty logical by the way. In the end you've got to weigh your own risk tolerance and other life details. Ask yourself how quickly can you honestly pay it down. Depending on income and expenses, I've seen people pay off that much debt in less than a year. In that case I tend to lean more toward the conservative side. Then again, if you're able to refinance it into a low fixed rate then you may be better off taking advantage of that.
Either way, earn and learn. Take advantage of what your broker offers and build your business. Build you some cash reserves, because like Ken mentioned, you're going to have some slow times that you have to survive. In the end, the market may make this decision for you.
Good luck, and if you are interested there is a REIA group that is meeting next Thursday in St. Augustine. https://www.meetup.com/JAX-Cashflow-Community/events/fqmzmlywlbfb/
