How will you be paying your private lenders since there will be no rent collected?  

And if the builder is seasoned and/or has good financial resources in place then you should be fine. 

And while you are doing that you can sell a few of the nicer properties with owner financing and sit back and collect $199/mo per property for doing nothing.

Even if tenants pay base plus cam to landlord they generally do not have the funds to cover parking lot or roof right away and landlord has to pay upfront and collect cam over the years to make it up.If you want to fully update the center for new roof,re-coat and stripe parking lot, new paint and facade etc. it could run into the 6 figures for that or more depending on building size.There are companies that buy shares but they want a discount. 

I am in Atlanta, GA but haven’t come across any knowledgeable resources yet, any recommendations would be greatly appreciated.  

I'm getting mixed messages between what our lender is giving us, usmortgagecalculator.com and several other resources.

Spreading your limited resources on multiple marketing channels won't get you more deals, it'll actually hurt you.You should examine what your strengths and weaknesses are, and understand what it would cost you to deploy one of those channels in an efficient manner to make your own decision. 

If you don’t know of any local LO, I would recommend you contact Upen Patel who lends Nationwide and see if you both can come up with some viable options after some self discovery about you and all available resources at your disposal.

Education, networking and some resources will help greatly.

For example, we aim to collect rent that is double what are mortgage would be.
