While you will definitely need to line up funding I think the harder part is finding reliable contractors that  you are comfortable with.  1. 

My regular personal biz is a little slow, and my monthly nut is very high, I'm finding myself too close for comfort as far as the amount left in my bank each month, especially after April, with both property tax and my personal that was due!

Then watch how fast they sign.The tenant is comfortable now and obviously doesn't see signing it as an urgent matter.

, comfort levels, etc. 

Nicole, I would wholeheartedly suggest to you to stay away from RE investing until you acquire more knowledge - practical and theoretical, and become comfortable with it.

I know that the debt is unavoidable but my question is if I'm good in math and and working with numbers, and love business(someday want to be a CEO or entrepreneur) what major/minor should I look into that can help me obtain a nice FT career(not a job) that has a nice salary so once I finish college I can pay off my loans and invest in RE comfortably.

I am all about networking with other RE professionals and REI's, but I am not comfortable not having control of the situation when it is my blood, sweat, tears, and CASH on the line.So, have I missed something?

My hobbies include traveling, reading, hiking, gaming, disc golf, scuba, consuming art especially concerts, and relaxing.

It's not a formal document, just a simple paper that spells it out and gives them comfort you won't be taking them to court later. 

I think other things come into play like you're comfort level in buying another one, your ability to manage another, your cash flow situation, your reserves, your other income streams (if you have some) etc.My personal approach is that I look for the best deals when I'm comfortable buying something.
