Hello,
1st of all, Very smart of you to appoint your children as members and use that structure as a strategy for tax savings, investing, etc.
2nd, I'm so sorry you were steered in the wrong direction for your Ga properties in Stone Mtn and Riverdale. I live and invest in GA, and both areas tend to be good rental markets; but you absolutely "must" know the "hot pockets" (and cold), in order to pull the proper returns out of your investments; and I think that's something the company didn't proper explain to you (assuming they knew). Carterville, GA is another area that would depend heavily on knowing the pockets. I tend to steer aware from each of these areas for different reasons; however, if I were to invest in a buy and hold in either of the 3 areas, I would only do so if each properties...
A.] Is occupied with a long-term, good paying (or S8) tenant who wanted to stay.
B.] Has rental and occupancy history to warrant the risk.
B.] Has ROI of at least double digits.
C.] Has a performing PM company in place.
I know this doesn't help you in hindsight; but in future endeavors of any US properties, (at minimum) it would benefit you to follow this formula. I hope this helps a little, and I wish you all the best.
