Moving off campus makes it more difficult to just meet people (vs being in a large dorm). But all the advice is the same–join a club, form a study group, get involved in a church, hang out at the student activity center (they will often give lessons too which is a fun way to meet people).
Don’t just meet them–when you do make a connection make a plan to see them again (don’t be pushy but sometimes you’ve got to take the lead and invite people into your life.) A lot of “friend making” is networking–you meet one person who introduces you to others who have a party where you meet more people etc (one reason clubs and sports are good).
Sometimes you’ll find yourself wanting to meet people but not sure how to strike up the conversation. “How to Talk to Anyone” (93 tricks) by Leil Lownden is an excellent book.
You don’t need all 93! Just pick three to start and try them out (I can personally attest to the success of these methods–they’re easy too). They are geared for different social situations.
Bottom line–I wouldn’t transfer–I’d change my way of looking to meet people. Good luck!
