Could describing *yourself* in a housing ad be considered "descrimination"?

[Paul N.]

Hi all,
Long time no visit. I have a question regarding posting what might be considered a discriminating ad for my rental. Note that this would be a "share with owner" situation, and not an ad for an apt, or a unit in a multi-family house. Now, according to Craigslist,
there are all kinds of things that are illegal to state as preferences,such as "Christian home", references to sexual orientation, and obviously, race, among other things.

I believe I have a bit more leeway with a share with owner situation
(correct me if I'm wrong), but what if I described *myself*? For instance:

"Older, SWM, straight, smoker, not particularly religious, has room available for rent for one person, share rest of house"

In this hyper-politically-correct world we now inhabit, would posting the above put me at risk for getting slapped with a charge of posting a discriminating housing ad? Obviously, I very much DO want to be discriminating about whom I share my home with, but adding something like "seeks same" or "seeks compatible housemate" would make that rather obvious

What about adding an insincere "All welcome, M or F, No pets, 720 FICO or better required".? Would that cover my butt?

Basically, I guess I'm looking for advice for how to write an ad

for a house-share that weeds out most of the people I wouldn't want to share with, while toeing the line on the ad-copy and keeping it legal. Any advice from veteran landlords or property managers would be most welcome. (The property is in SC, if that matters)
