Umbrella insurance for citizens policy holders in Brevard county?

[Cindy Joseph]

We purchased a duplex and Brevard county Florida. We are living in one side and getting the other side ready to rent. Because of the age of the house (1957) location citizens insurancr is the only insurance that will ensure us. They have a liability of $100,000. I would like to purchase umbrella insurance for extra liability coverage when we get tenants. However the minimum liability coverage needed for umbrella is 300,000. We are hesitant to make an LLC in case the bank will require us to pay upfront and also loss of some of the tax benefits. Is it worth it to get excess liability coverage to bridge the gap and then get umbrella? It would be about 100 month extra for an extra 200,000 liability. Then we would have to pay the premium for the umbrella as well. We are already spending 5,700 a year for home owners insurance through citizens and flood insurance. I am just not sure if this is worth it. What does everyone think who has been a similar situation?
