You do need to take homeowner education training (online) and landlord education for 2-4 unit properties. 

Are there any online and/or national banks that are open to this very low risk proposition where I can find an interest rate under 4.5%? 

I've had many different scenarios played out, worst being getting a writ of possession from the Sheriff and them showing up in bullet proof jackets, drilling out the lock on the door only to get inside to have dog feces/urine 1" thick throughout the entire home! 

You can also check their reviews online at Google, Facebook, or Yelp.

Need not to down play any profession.

In this day an age, syndications are done online and its called crowdfunding.

As new units came online existing tenants saw the writing on the wall and began looking for new places.  

You could use the BP calculator (5 times for free membership) or find some available online for free.The most important thing that is going to get you ahead: commit to do 1 thing at least every day that is going to get you closer to your goal of acquiring and creating wealth through real estate: read, analyze, go to open house....Hope that helps.Good Luck

I have googled and found several online, but nothing with actual reviews from users/investors.

I’m looking for a place online to get my real estate license in Tennessee  .
