LLC or S Corp ? WI or AZ???

[Elvis Dur]

I want to open somehow of a legal entity where I can add my rental properties located in Milwaukee WI. and all other  real estate related activities that I have going on in the state of AZ.

I am  Realtor in the state of AZ and I do some property management here in Phoenix AZ.

Any ideas where should I open the LLC in the state of WI or AZ?

And another question is LLC or S Corp for RE? What's the best option?

Thank you all in advance!!

Happy New Year 2022!!
