This often happens when the assessor office creates a separate lot for tax purposes but the larger lot of which it is part was not legally subdivided.Also, as pointed out above, tax liens, weed abatement charges, HOA, etc all usually survive.  

@Eric Lahoda, is it typical in your market to charge fees for those items separately?

Keep personal and business finances separate.

The company I mentioned above actually found the real issue (more on that in a separate post) and I visited their office yesterday. 

I have an existing LLC for a separate investment property with a partner. 

We've posted numerous times that +95% of agents only know how to work with owner-occupied transactions which are mostly emotionally based transactions.So, why are you even bothering contacting these agents?

First, ensuring that each property or group of properties is held in a separate LLC can limit exposure, confining potential liability to the specific entity involved.

But, they are structurally separate and both income-producing.

@Miranda LeMaster If your agent can not offer you a good commercial option, then you are working with a personal lines agent and you may want to think about making a change sooner than later.Ideally you want to have 2 separate insurance programs.  1 for your personal and 1 for you business/commercial exposures.  

Some of these people have emotional issues; some have an inability to comprehend social norms; some are ********, and some think they’re being funny.
