I am realtor in Polk County Florida and have a vacant land listing in the same county. A tree from the vacant land fell during a storm.

Are you asking whether you have any liability as a realtor listing the property? No, I don't believe so, unless you had knowledge that the tree branch was going to fall.  Damaged homeowner should talk to their homeowner's insurance and make a claim since the damage occurred because of a storm.
