While for rental property it is not required that you create a partnership, I am of the opinion that when you have 2 or more owners that are not married to each other and not filing a joint return, it's the better way to go. Besides, creating a partnership in FL is dirt cheap compared to some other states. In fact, it's less than $100 to create a General Partnership in FL, based on what I see right now at http://form.sunbiz.org/pdf/cr2e074.pdf
Also, the cost of registration as well as the cost of the TTX program and the filing fees can all be claimed by the partnership as a rental expense, if that's the only reason for which the registered partnership exists.
