Anyone know of any good sites listing apartments or houses for rent in Arizona? Thanks.
Try Craig's List (they're all over, but Arizona shouldn't be hard to pin down).
Ditto Craig's. I started advertising my houses there, whopping response compared to local newspaper. Since CL is free (for now) and reaches a much broader audience, I plan to continue to use it. The local paper generated only a couple calls and the ad was a whopping $120. I linked to it below.
There's also City Data forums. You can ask there if anyone knows of good places to live/rent/or seek housing online. It's very area specific. Here is City Data forums.
