Question about umbrella policy as an alternative to LLC

[James Park]

I currently own 4 rental properties and want to make sure that i am properly insured. All my properties are insured with All state with a $300,000 liability coverage. I called my agent to get a umbrella policy but he tells me that all state no longer offers an umbrella policy for land lords.

How much liability coverage should i have for each property? Can i get an umbrella policy through state farm while all my properties are insured with all state. What are my options?

Thanks.
