I tried calling around the respective govt bodies, but wasn’t able to get clarity on whether out-of-state investors can setup such a facility.

You'll need to provide Entity Docs for each LLC that is a part of the transaction so that the underwriters can review them all the way down to the natural individuals/warm bodies. 

Make sure you have all your documents scanned and ready to e-mail to them,  and ditto all your notes of conversations, etc.  

Most places I see in this range don't look so great and a quick scan through the reviews makes it easy to find what they are doing wrong.

You need to contact the governing body that has jurisdiction over the zoning laws for either the incorporated or unincorporated of the county or city for the plot you are interested in building on.  

Or use an e-card like Linq which someone can scan and download all of your information.

Response to #1: Some lenders allow for layered entities while others want warm bodies/natural persons to be direct managers.

i bought property at tax sale auction in Dekalb county Georgia, over 12 months ago, now i am doing barment,  i published ad news paper,  i sent 30 days notices to ex owners and all parties might have interest,  and the property now it empty / unoccupied.my question is: if 30 days notice expired and no body redeemed, can i enter the property and start to fix / repair the property, and rent it??

I’m currently scanning the MLS while also trying to connect with wholesalers for some off market opportunities.
