You'll be comfortable with investing in ATL because you know the area and your team, and you get to write-off your trips back to ATL to visit friends/family.

I'm comfortable with the Texas contract, so I may see if I can use some version of it for this purpose.

Depends on where you feel comfortable living.

Find a realtor you are comfortable with and knows the market well.  

My attorney suggested to me that I specify a certain amount of equity that I was comfortable at risk in one LLC.

You might offer $11k with owner financing if you're comfortable with the deal.

This will lead you to secondary and tertiary markets to find deals, which lead to additional operational challenges if you don't have an appropriate asset management strategy designed for smaller markets.  

Thanks for the thoughts - I can probably get to a point where I'm personally comfortable with it, especially since they've been there without incident for a few years.From an insurance/liability perspective, should I be concerned?

I have looked at PA (more Philly though) and just never got comfortable that I knew enough to invest (being from out of town) or that I had help I could trust.  

I would suggest 1) Commit to attending the next 6 months of REIA meetings, 2) read the Bigger Pockets getting started guide, 3) stay active in these forums without necessarily asking for mentorship -- just ask questions and engage in threads.Once you've done that, you should at least feel comfortable enough putting out some form of marketing to find a deal that fits your plan.
