Rental Dwelling Policy How Can I Buy An Umbrella Liability Insurance Policy Without Having A Home Owners Or Renters Insurance?

How can I buy an umbrella liability insurance policy without having a home owners or renters insurance? - rental dwelling policy

I own a rental property in Houston. Since I live abroad and have no owner or tenant insurance is insurance for my business as an investment property does not go to a comprehensive policy 1000.000 U.S. dollars to write. My policy of investment in housing liabililty property features a cover of $ 300,000 for the same thing.

Is it possible to buy an umbrella policy 1000.000 dollars? The names of other insurance companies?

Thanks
