My D graduated college in another state in May 2021. We bought her a used car in that state the summer just before her senior year. Actually, she had to buy it all on her own, but we funded it. Since we were not present for the purchase, nor we would ever be driving it, it had to be titled in her name and our insurance required us to remove her from our policy and she had to get her own in that state, even tho it was a temporary residence. She did all of this using her college rental apartment address. She then also had to, by law, get a new license in that state. When she graduated, she moved to a new apartment in the same city. Shortly thereafter, her car needed to be re-registered. Since she was living at a new address, she ended up having to due a change of address, etc, but she figured it all out. She files taxes where she lives and works. Most of her banking is online, but she uses her current address now for all of that. She has one small college loan and the mail for that was coming here until recently, but she updated her address last month and changed the statements to online access. She also registered to vote in that state so she could vote in the 2020 election. So essentially, she started changing her address for most things just before her senior year of college, even though she lives in rental properties and has already moved once.
The only mail we still get for her are credit card offers.
