One more thing, what if I have an umbrella policy that covers the worth of my assets, will that not be sufficient to protect me against liability? 

We currently have an umbrella policy which covers our primary and 4 investment properties.

Then I would consider an umbrella insurance policy to increase coverage over all your properties.

As mentioned I am new to this and I am have been a bit confused trying to determine all the differences between homeowners, landlords, umbrella policies, etc.

You may want to explore other coverage such as an Umbrella policy (for additional Liability coverage) and Workers Comp.

@Julie Williams I personally invest in my own name currently, just make sure you have a good umbrella insurance policy.

landlord insurance and and umbrella policy (which you would need with your LLC anyway) are all you need -- and keeping you properties well maintained.Again, the LLC is there for asset protection, not for tax reasons, unless you are investing with a non-spousal partner. 

(Umbrella required limits.)

Protect yourself with an umbrella policy.
