Commonly, if all are on the same playing field it is a lot easier.
When one has the edge, a house maybe, it helps. But as another poster mentioned, it can be a lot of money to have to handle.
Dorm floors are more usual as Astro said as I know where she went to school. Many of the Fraternities had the same thing and some are doing quite well. But, times may have changed since I was there.
All GLOs at my Alma Mater PSU-Ks, have houses and have for years.
The main thing is to have a place that you all can get together with each other. If a floor, you can open the doors for a good old gathering!
If a few members have a rental house off campus it too can give a central place to hang!
