I am currently going to my local college to eventually get my CPA so I have good math skills and a general understanding of money/investments/risk.

In VA, it's really easy and a great way to pre-screen people, it's like getting a public background check.  

Wondering what's the difference between a real estate broker and a real estate agent?

These are professionals with additional training and a stricter code of ethics.

Full charge escrow officer and a title officer keep you out of trouble .. and realtors are suppose to know the line between broker and practicing law.. 

@Daniel RibeiroI know the 19th already passed but I will second the notion for @David Ribardo.He is a realtor and a real estate investor in the area

Should I create and EIN and a business checking account for the LLC?

At the end of the day, your tenants will fight to get a lower rent and a better arrangement.

Craigslist gives a very good baseline, and a variety of rentals to compare to.
