I'll ignore some of the insanity as others have got it covered, but here's an idea- if you don't have a house, why not considering playing it up as a positive? My college was very similar to Linfield- small, private, liberal arts school with 3-5 fraternities and sororities. The fraternities had houses, the sororities didn't. Sounds pretty similar to Linfield.
One of the challenges that several of our fraternities faced was getting enough people to live in. Some people, including my husband, either didn't join or disassociated when they found out they would have to live in the house. With such a small student body and not a ton of interest in Greek life, the fraternities often struggled to fill all of their beds. I'm sure it is really hard on you guys to have had your house condemned (ouch
) and you guys want it back, but until you do- it's all about how you spin it. "We have a fantastic, close-knit brotherhood and we do a lot together, but we also live in the dorms/apts/whatever and are able to be really involved in other aspects of college life".
Yes, the spin may not work, especially if you guys don't embrace it & believe in it- but find a way to put a positive spin on the situation and showcase what you have to offer. In this case, not having a house can be a huge perk to some people. Just a thought...
Also, since you don't have a central house to congregate in- be visible. Wear letters, have lunch together on campus, host activities. Show that brotherhood goes beyond the house. Any group should do this regardless, but for you especially this is important.
Good luck!
