Brad, I'm not an attorney, but I have always heard that it is best to set up your LLC in the jurisdiction where your property is located, unless you are trying to get the benefits of a specific state's corporations law (Delaware, Wyoming, etc. - ask your attorney). We have several properties in Valdosta, and our LLC is set up in Georgia. Remember - Since you've already purchased the property (in your own name?), once you set up the LLC, you have to actually transfer it to the LLC or the LLC will be of no benefit to you.
Again, I am not an attorney or accountant, but my understanding of the new tax plans is that they give preferential tax treatment to any "pass-through" income, and so long as you form a pass through entity (LLC taxed as a partnership, for example, and not a corporation that is taxed at the entity level) you should be good. However, with real estate you really shouldn't be paying taxes on the property for several years due to teh depreciation anyway. If you do any significant rehab, you really won't be paying taxes for a while.
