I would like to know if this is feasible while maintaining a job and keep in mind I won't be stationary in a city for longer than 3 years.

Would trying to go through a local (in this case New Orleans, Louisiana) based lender be feasible?

Then research the laws in your state to see if the strategy is feasible in your locale.It's very state specific.

I am a beginner and to me this seems logical, but may not be feasible as I have not seen it discussed much here.

The problem is not that I cant afford it is that whether I buy a 400k location or a 750k location getting even 1% return IE 4k rent from the 400k investment does not seem feasible.

I also like the idea of being able to leverage banks' money into an investment rather than throwing all of mine into some kind of retirement account and relying on interest for any real growth (not that that's not feasible, just not for me).

That doesn't mean those zip codes are bad or not feasible areas for rentals whatsoever...just means I can't give you a fair answer to your questions. 

All 5 are rented, but with two  are on month-to-month leases, so I could feasibly get those empty pretty easily prior to selling if that's what the investor wants (I know inheriting tenants is a very opinionated topic).What are some good tips for presenting my inventory to help me get the best price?

Getting a broker's license would be a good thing to have, you just need to be sure its feasible for your life structure at this moment.

There are municipal requirements and zoning so I'll double check feasibility in this regards.
