Are you in the US? In the US you still have a right to discriminate against potential roommates, and I actually think it's the right policy. It's simply too close a relationship to effectively enforce a non-discrimination policy - not romantically, "whose dishes are these" close. It's illegal to express discriminatory preferences in advertisements, but if you don't like singles from Arkansas (for example) you don't have to let one into your home.
With my crystal ball (or wherever I'm pulling these answers from) I say leave it toward the end of interviewing, especially if you get solidly gendered female.
- One other thing, can you keep it confidential? My girlfriend and I are transsexual. We don't want this to be a surprise problem later. Really we'd rather you never notice, but we thought it was better for you to know now.
The decent-human-being answers to that are either "no problem" or "thanks, I'll find somewhere else to live." You can't control which, but do you really want to stealth or smooth-talk your way into living with prejudice?
