If your real goal is keeping a clean U.S. base for banking and investment purposes while you travel, I would look at a legitimate domicile setup before I would look at renting a place you never plan to live in. In a lot of cases, paying for a room or property just to maintain an address becomes the more expensive option and still does not simplify the paperwork the way people hope it will.

Full disclosure, I run Your Best Address — a mail forwarding and domicile service in South Dakota. We've been helping full-timers, van lifers, and people in transitions like this since 2005.

I became the owner in 2024, and we work with a lot of people who need one stable U.S. address for mail, licensing, registrations, and general continuity while they are mobile. South Dakota is often attractive because it is one of the more straightforward domicile states for people who are no longer tied to one physical home base.

What usually matters most is not just having any address, but having a setup that is consistent and defensible across the accounts and documents you care about. If you want, I can outline the practical pieces people usually think through before choosing a domicile state.
