Any reference point of return?  

I would love to have a call with someone with an intimate knowledge of what I am looking to do or be referred to a rockstar commercial agent in eastern Florida.

@Paul DentingerRecommend exploring as many sources as possible to get referrals AND cross-reference them to get as much accurate information as possible.Check out NARPM.com, BP’s Property Manager Finder (BiggerPockets: The Real Estate Investing Social Network), etc.Also, encourage you to learn from the mistakes of others - by reading posts here on BiggerPockets about owners not having their expectations met by their current Property Management Company.

This will allow you give a reference point on how much potential rent you can receive.

Can someone share where in the Atlanta ordinance it refers to shart term rentals as 180 days or less?

And prior to that, it likely took her hours to research this specific topic, and years to get to the level where she can answer without having to read the reference book.

This is not 100% financing...I am referring to NO CASH, no cross collateral, NO MONEY DOWN.

I think you are on the right track comparing options - however I would note that there isn't really a differentiation between "DCSR" and "ARM" - there are a lot of 5 Year ARM options for DSCR Loans so theres overlap - maybe you are referring to a true 5-year balloon bank/credit union type loan?

Get references.

(I am referring to Illinois Series LLC).(1) Do I need separate EIN number and separate bank accounts for each Series in IL OR I can have only one EIN for master and one bank account?
