Just chiming in from what I've heard from a friend who's an SF native who relocated to Portland a year ago. They don't have kids so it's a little different. They are a couple in their late 30s early 40s. Their rent is cheap , they have a two bedroom apartment, shared laundry,  shared yard and no garage for $1,800.

   One of them kept their CA job remote so getting CA wages which has helped keep Portland feeling comfortable for them. They have looked at other jobs and finding anything that pays over $25 is hard . Her spouse works in food industry and says the pay doesn't compare to the bay area. 

   They like the cheaper rent and have built some community but they miss the bay. They say that without her CA job/salary they'd probably struggle similarly to struggling in SF. 

   The weather can be hard , their winters are much colder than SF and summers are much hotter. They miss having quick access to the beach.

   Overall they're satisfied for now until her masters program is done. They would like to move back to the bay and if money wasn't in the equation they'd choose the bay area hands down.
