Does anyone know when university of marylands fall decision for transfers usually comes out? I know they said mid-July but I’m getting antsy because I need to find housing if I get in or figure out what I’m going to do if I don’t 
According to their website, decisions will be released Mid-July for fall transfers.

Although you should not plan for either scenario, you should have a basic idea of what you’re going to do for either scenario.
It doesn’t hurt to call though, admissions office may provide more information concerning the precise date of decision.
University View apartments have spaces for the Fall (the Varsity is sold out already). As for calling admissions, if it’s anything like it was for the early decision group in April, then don’t bother. You’ll get a different answer from each person you speak to. I’d be prepared with a plan B just in case.
