Ask HN: Good time to ask about working remote?

I'm looking around for something new, but would like to stay where I am. I believe I have the experience and ability to work remotely, and my current situation has many people throughout the company that work remote. My question is, when is a good time to negotiate working remotely? Should I bring it up right away in the initial phone interview? Or wait until an offer is made and make my case then? Or somewhere in between?

By "good time" I mean the best odds of landing a good remote job.

Thanks!
