If a neighbor is a pain in the butt and is calling in complaints, that is really bad. 

Personally I won't lose a friend over a difference in profit sharing (unless really distressed like needing this extra money to feed my family).I would use the pain as a sharp reminder to never get into any deal with anybody without prior and clear agreement.

I need to go outside to the basement which is a pain in Wisconsin winter.

That's all I really need them for, though if there are major repairs I don't mind having them hire a professional for it (ie if the the motor in the furnace needs to be removed and blown out because the tenant failed to replace air filters; replacing doors is kind of a pain so I'll pass that off even though I can do it, stuff like that.) 

I currently live in New York, what state would make the most sense (financially) to open up and LLC for my property in PA: in the state the property is located; in the state I currently live in; in some other state that has low income tax?

We have people squatting in some of our houses for over a year that started before Covid19, so I feel your pain.

You would be subject to ordinary income at this point, which would be even more painful.  

I wouldn't, it's a pain to find a home. 

It's a long-term game, so if you want to be part of the growth, you have to deal with the growing pains too.

You’re obviously more valuable than the average buyer unless you’re a pain to work with.
