Nothing wrong with getting an umbrella policy either, just in case.

I'm arriving at the conclusion that most of the variety of interests I have fall under the umbrella of real estate services.

I mean, we got a smokin' deal (IMHO) that provides a $5mil umbrella for only $1,300 / year, on top of the $2mil primary policy.In 2017, we're planning on scaling the business by acquiring at least a few apartment complexes (20+ units) in other states while still living in CA.

Pair that with a solid umbrella liability insurance policy, and you're fine. 

I'm leaning towards just an umbrella policy, but one thing I would like is to have my tenant cut a check to someone other than me (a business name, for example).  

Or keep things in your name and bump up your insurance (usually an umbrella policy) to cover your risks.

I just kept it, collected the rent, kept basic track of expenses and took out an umbrella policy just in case.  

Looking for advice / insight on getting an umbrella policy for an investment property.

I simply thought that since it's real-estate, there may be something extra I need to do, since I may be purchasing properties under the LLC in the very near future, if I do not have a separate LLC for each property (I was told that's the way to go) or have a large umbrella policy and cover multiple properties.

A good agent will also learn your business and get a proper umbrella policy in place.
