Arizona LLC, Wyoming holding company, California resident

[Kevin Gillies]

I have 4 short-term rental properties in Arizona, I live in California. Looking to put them in LLC for asset protection and have Wyoming holding company. The question is do I do have 1 AZ LLC Or separate them. Then have the Wyoming company hold them. Do I need an EIN for the Wyoming LLC? Does it need to qualify to do business in CA? Does qualifying In CA lose my anonymity and protection? Or is there a better way?
