Housing Advice

I am currently having a housing dilemma. Im going to be a junior next year, and I know that most people get an apartment off campus. However, due to some unforeseen circumstances, I don't have anyone to get an apartment with and I don't think I can afford one by myself. So, the only option I can think of are the on-campus housing options. I know that for RAHPS you have to live with like 3 other people and I don't really trust the lottery to give me good roommates. I guess I'm just wondering what the other 2 options are like (Stackwyck and Polytechnic). Which one's better? Also, are there any other options for someone in my situation?
