Not to deter you from getting an LLC, but I would look into getting a Umbrella Policy for your AZ home and get an amount of coverage that you feel is necessary.

Be intimately familiar with it or find someone that is. 6.Buy umbrella insurance to CYA. 7.If you do not hire a Realtor and are not familiar with contracts, hire a lawyer to look over.8.Make sure your credit score is good and you have liquid assets for more than you think you need. 9.Talk to an investor friendly lender to get familiar with the types of products. 

Once you're under the management umbrella of REI you'll be assigned a customer service rep that will reach out once a month regardless of what's going on so there's open lines of communication. 

Quite frankly, we do so much coaching with new investors under the umbrella "buyer representation" and not getting paid for it.

I'd do a landlord insurance policy and umbrella policy regardless.2) I may cash out refi the second and third duplex (both bought in cash) if/when interest rates drop to buy my dream home in the next few years. 

A last and very important part; I hear investors all the time talk about how hard it is to find good deals in TCM market, even asking "is there any 1% rule properties left" and I just laugh because in the Central MN market the #'s can be epic compared to TCM market and others.

We (wife and myself) do have an umbrella policy. 

I am looking for an umbrella policy that covers my rentals in Florida, Alabama and North Carolina. 

6) Umbrella Insurance Policies/LLCDo most investors have an umbrella policies for personal belongings and assets?

It's probably equivalent to being struck by lightning.If you are still worried about it, get an umbrella policy of $1 million for around $200 a year.
