Clarification on umbrella policies

[Patty Tran]

I see numerous threads on umbrella policies here, but I am still not 100% clear.  Few questions.

1) Does the umbrella policy on my primary residence also cover any rentals I own? I think the answer is it depends on the insurance company, but not 100% certain. I have an umbrella policy with Amerprise for our primary residence and our automobiles.

2) Is it common to own a separate umbrella policy for a rental? Meaning having one policy for primary residence and personal automobiles and another one for rentals.

3) If I transfer my rental into an LLC, does the LLC own the umbrella policy? Or does this depend on if I have a trust?

Apologies for reposting questions that have may already been asked. But there are too many threads and I am trying to find out answers asap.
