I guess I was a little short on the detail. We've owned and lived in our home in Michigan for 30 plus years, both my wife and I worked within 15 miles of said home for 40 and 24 years respectively, our children attended school from preschool - to high school in the town that the house is located in. Trust me, as long as I continue to own and arguable inhabit that house (at least part time while we're not off traveling) - we would be hard pressed to make a claim of domicile in another other state. Were we to sell the house - the door to arbitrarily selecting another state for the purposes of domicile would open. But, in our current situation ... not a chance. I'm stuck with Michigan's vehicle registration fees for the time being.
