House Hack a Primary Residence Out of State?

[Nella DiBenedetto]

Hello! I have been using the house hacking strategy for the past three houses that I have bought in Salt Lake City, UT. I would rent out a portion of my home, while I went off and worked as a travel nurse in other states. I would come back to my primary residence in between contracts (1-2 months at a time before I left again). This time, I am working in Oregon and am purchasing a home to house hack here while I am working... My question to you is, since this is my first time buying out of state and making it my primary residence, do I have to get an OR drivers license and register my car to show that I am living here? Or can I just change my mailing address and pay OR state taxes? After a year of living here, I plan to move back to Salt Lake City, so I don't want to register my car and change my driver's license if I don't have to, but I also want to make sure I am doing everything correctly with the government/my lender etc. Thank you for your insight!
