The Beta house at Kettering University, Michigan (Formerly GMI) actually is two chapters within one. When the two schools merged 'back in the day', the two chapters came together...somewhat. First semester the A-Chapter gets to live in the house and then second semester the B-Chapter gets the house. It is pretty unique, they actually rush seperate too. That chapter also owns a bus for them to get around in.

I think that other fraternities at that school are the same way.
Other than that, I know that a lot of older Beta houses were used for housing during the wars.
