Thanks for your responses everyone. I appreciate it. There is some good information here.
For my own understanding, if the building is owner-occupied (which in my case, it will be, I forgot to mention that in the first post), a normal homeowners policy would suffice (via @Frank Chin). The policy will include liability to a certain extent (if it doesn't I will inquire about that). However, an umbrella policy should be added to pick up liability outside of the original policy's coverage including my personal assets.
The next question I think of is, how much liability coverage do you need? Is there a rule of thumb for this? How do I know that my homeowners liability policy isn't enough and should get an umbrella (besides using the umbrella to extend to personal assets). I'm assuming that is based on property value and even personal asset value?
If I end up taking the LLC route, I can choose a Dwelling/Fire or BOP (@John Mocker) . How does that work with the property being "owner occupied"? Is the reason that I can get Dwelling/Fire because the property isn't really owner occupied? (LLC owns it, not me - I pay rent to LLC). The benefit would be because its cheaper like John said. However, I sacrifice the higher limits of a BOP. That's a decision I have to make.
Out of curiosity, can you not get a normal homeowners policy with an LLC because it is not owner occupied? (which explains @Mike McCarthy's last line saying landlord/property insurance plus umbrella and not homeowners plus umbrella)
