I am reading about Wyoming LLC's being best for anonymity, but I want the most protection with the least complication! 

I am the only member on the LLC, I am married but I would buy this next property only under my name if it avoids complicating anything. 

I am curious though, if these deals are as sweet as they sound...I’m also curious to hear about the complications of owning/investing overseas?

While there are more complicated ways to measure this, the most practical way if you care about answering the question "how much do I make every month" is just income - expenses = cashflow.

Separately — and this is a more minor gripe — it was complicating my tax situation to pay state and local income taxes in a place I didn't live anymore.I pitched to my parents that I would sell the place and roll it over into a comparable property closer to where I live.

I am finding it complicates the relationship because I want to be friendly and neighborly yet also need to set boundaries as I know landlords need to be firm sometimes. 

What are some less complicated ways to go about passive investment?

That is kind of complicated, depending on the scope of the project.

I would say I won't hire a lawyer in the beginning, thanks to Georgia eviction law, but I will definitely need one if things become more complicated.

Additionally, the record number of apartment unit deliveries in recent years has led to increased supply, putting downward pressure on prices, occupancy rates, and rent growth.Operational costs have also been on the rise, further complicating the financial outlook for multifamily properties.
