sophomore fraternity rush

I am rushing as a sophomore in the fall semester and am wondering how much does being a sophomore during rush affect me? I received some bids this past spring and I ended up rejecting them because although they felt like I fit into their house and they were great guys, I just didn't get the same "home" feeling when being there and joining a brotherhood is a big decision I want to be 150% sure on. I enjoyed speaking with the guys, but i found some houses that I absolutely love because i know some guys in them very well and I'm worried that they might not take me since ill be a sophomore. Does me being a sophomore matter?
