As what I know Minato is the youngest who became Hokage. He's already Hokage that time I guess.

Right. To maintain his immortality just like what Orochimaru did transferring from one vessel to another.
Maybe he got a good chance to took Obito in Kannabi Bridge while he's dying. Since Obito is an Uchiha too and he has a young body, it can make him more powerful. See why Orochimaru was really interested to make Sasuke to be his vessel because Uchiha Clan were so powerful and Sasuke's body is young and fresh. loljk
