@Modorney: This sounds like a great idea and something to look into! Thanks
@TSteven:

I am aware of that. Which is why I am interested in trying to push for one haha
@lucgreek: Definitely a negative. I really want to have that "Greek Life" experience for my Chapter and a house is really important for that. I've found some 5 bedroom homes in the Daly City area (just outside of SF) that are approximately $500k. But yeah, housing prices here are through the roof.
@NinjaPoodle: Definitely something we're facing here. Being an art school, and the red tape that AAU has, its really hard to get things planned and organized. We have grown up a lot in the past 2 years and I'm glad to say we are finally on the right track to getting us in order. Finances is definitely a big problem, which is a symptom of our numbers. We need vigorous recruiting. We're a small Chapter with 19 "actives" but only say... 12-14 who show to things. This wouldn't be an issue if we had, say, 40 Brothers. AAU's turnover rate is huge too, so keeping people in is a challenge.
For housing, I was figuring our only options would be A) Get a floor in a dorm devoted to Greek Life, B) Buy a house which would be more like a "lodge" a little outside of Downtown or the city such as Daly City or Alameda, C) Rent a house and pass the lease down year to year (though this would need a co-signer), and D) Buying a small Plex with different units that can be converted to a House. Though that, I'm sure, is hella expensive.
Thank you everyone for your thoughts and experiences on this, it is really helping me get some ideas rolling!
