How to not break laws (business license on rental, taxes, etc)

[Mary Jay]

What do you guys do to make sure you are not breaking any laws?

Do you obtain business licenses on properties? Ive heard it is important to do.

Also, who do you pay taxes for operating your business (Business taxes on your rental that is in LLC) ? Maricopa county? City of Phoenix/Glendale/Peoria etc?

Also, how much in property (not business) taxes are you paying? 

Anything else am I missing that we need to do to make sure we are operating all correctly?
