I'm on the Q and based in MFR (by choice...more or less). I drive from the Sac area ~ 5 hours. When Winter driving gets iffy, I fly (2 legs, SMF to PDX or SEA then MFR). I have a good guest room setup for the 5-6 nights per month I'm in base (or an early morning show the following day).
I'm former Army, I've got a little kid, time at home is precious, and the automobile gives me flexibility to get to work on my own schedule while hauling a lot of stuff.
I'd consider staying put in Redmond and driving. Fly when the weather turns bad. Suck up those first few months of reserve time with a crash pad. Crew rate at the Shilo is ~$60. Bask in the glow of your small children.
Keep as much normal as you can. Moving to Seattle sounds crazy to me; disruptive, expensive, and burdensome.
