Sixth, I do not tolerate tenants that reject my communication.

Not saying it's going to happen but it's good to build in tolerance or at least know you can handle it if it were to happen. 

Will depend on several factors like the type of property, type of tenants, your risk tolerance, other assets you own, your estate planning, laws where the property is located, etc.Any lawsuits would be limited to the assets of the LLC and not your personal assets (assuming you run the LLC appropriately and the corporate veil is not pierced).

A bigger worry, in your case, would be where you're going to live; duplexes tend to be in worse neighborhoods (although honestly there aren't any REALLY bad neighborhoods here), so it depends on your tolerance for shenanigans around your family.

It ultimately is going to come down to what your risk tolerance is and how much time you have to put in the work required.

It all comes down to what risk tolerance you have.

None of us are going to know your internal risk tolerance.

The safer bet would be to pick a more stable location in the Midwest, but everyone's goals, risk tolerance, etc is different.

You get what you tolerate!

But, my husband can handle a lot more stress than I can, so he would have a much higher tolerance level of nonsense, so in that case, enjoy the high returns if high handedness of the court system.
