Seattle should be okay if you already have a partner. Everywhere is growing insanely, but there's still affordable property out there (e.g. north) if you don't mind an awful commute, or are willing to do park & ride/public transport. With the growth rate, those communities will become really lively/ruined, too (depends on your PoV).

Could be worth waiting until HQ2 is announced though. Families won't necessarily be interested moving, but there's enough people around who'll make the jump, which maybe helps with prices? Who knows.

Seattle is expensive, but not near as much as SF.

I actually think here is one of the best places to leave. You can find SV level paychecks, no income tax, and housing for half of the price!
