With traffic, Tacoma isn’t very viable. Also I have a relative who commuted to his job in Tacoma from…west Seattle (granted they bought in the late 80s). It was an easy reverse commute (so close to actually 30 minutes?), going the other way is hard and you can only win with the train (sounder) or maybe bus. Link is making its way down to federal way soon (or already?) but that assumes you work near a station or it quickly becomes not competitive with driving.

My mom commuted to Redmond from Bothell when I was in high school, horrible traffic…and that was early 90s. You don’t want to do anything on 405 during rush hour.

You can also head west if you dare. I have a coworker commuting in from Vashon Island. I don’t think prices are that great on the islands though, maybe 30-20% less than Seattle, but you live by the ferry schedule and if you want something near the ferry dock you’ll pay a lot more for that walk on convenience.
