I was referring to the big houses they can easily buy when moving to the PNW. Its very common for somebody who was struggling to afford an $800K mortgage on a 3bd/2ba in CA to get a 6bd on 2 acres with a lovely view and a smaller mortgage in the PNW.
Anecdotally most people I know who have made that move just want the modest home they couldn't afford in CA, not a mini-mansion. Many have realized that owning a huge house beyond your actual needs is a maintenance nightmare.
