I retired 20 years ago and have homes in 3 states as well as my DP which might be anywhere. I call one home my primary residence although I spend little time there. Most vehicles registered there (no yearly tax or inspection and no emissions on diesels) I vote there, have drivers license there, file income tax there, and maintain a bank account there. I also maintain a bank account at all 3 houses, have ALL credit cards at a different address, another car registered at a different state than the rest, and income from 2 states that I pay taxes on. Looks complicated but has worked for 20 years.
