Another question on residency

You present so many variables that I caution you to get some professional help in making your decision. Simply stated, residency is not based on where you own property. You can own real estate anywhere and in multiple states, but you are only considered a legal resident of one place for a particular period. But, you have to make a decision and do as much as you can to prove your residency. That means obtaining drivers' licenses, paying appropriate taxes, registering to vote, registering and titling your vehicle and carrying liability insurance in that state, banking there (in other words, doing your business there). It is correct that TX, SD and FL are good states for RV'ers who are traveling most of the time, but you must be cautious and know the respective rules of whatever state you spend the most time in because they'll want to get your taxes, too.
