Can I pay my enrollment fee and choose housing at multiple colleges?

I’m really in between three schools, and I want to make sure I get my preferred housing no matter which I go to. So, I feel like I should be sending my enrollment deposit and picking housing ASAP. I CAN NOT decide which school yet, but I have some more visits in the next couple months. I don’t want to end up getting bad housing, so if I do this at all three, would there be a problem? I’ve heard that it’s totally fine and that it’s the worst thing you could possibly do, so I’m really confused. Is it okay as long as I withdraw before May 1? Can I choose housing w/o paying?
Thanks

You can only deposit at one school at a time.

As for housing deposits without an admission deposit, depends on the school, but not usually.
