As I'm sure you're well aware, the small multifamily space in metro ATL is competitive despite current interest rates. 

I have already sold by owner and am well aware of 1031.

My initial investment there started off a bit rocky.

I am just a guy who tends to give illegal advice, I guess.And finally, folks need to be aware that while many travelers pick the nomadic lifestyle for some of the awesome reasons: travel, excitement, variety, some pick it to try and increase their income to a level where they can earn their way out of terrible financial situations or decision making.

Are there other players in this field that I should be aware of and consider talking to before making a final decision?

It’s not a binary on/off choice.

I know so many people who have been ripped off by contractors.  

Many voucher holders are grateful for secure housing and are acutely aware of their responsibilities under the program. 

I have done a 1031 exchange before so I am aware of the rules.

One thing to be aware of is the FHA multifamily self-sufficiency calculation which determines if a property can generate enough rental income to cover its mortgage payments.
