@Nold R.In addition to the great post from Dave, possibly consider an option where the property is taken out of the LLC sooner rather than later and held as tenants-in-common prior to the sale, possibly setting you up in a position to take your share of the proceeds and individually purchase a replacement property via 1031 exchange. 

Separate LLC per Property: Maximizes liability protection but adds complexity and costs with individual tax filings.3.

My best advice would be to read through the contract carefully (builders usually have their own individual contract that's written for them and is leaning heavily in their favor).

and connecting with local REI individuals and attending meetups to learn from experienced investors. 

Connecting with a local agent who knows the Atlanta market well can help you navigate these choices and find the best fit for your investment goals.

Obviously a lot can change between now and next year as well.1031 would seem an obvious choice.

My contractor has one credit card for all of my individually owned buildings (jointly not multiple cards) and one credit card for the building I own in a partnership.

Break down your rehab into individual jobs, for example get a electrician for electrical work, a plumber to repipe the house, a dry wall guy to close out the walls, etc.

@Brody Veilleux I keep individual checking accounts for all my properties and have mortgage accounts on most of them.
