Ask HN: Coming urban housing price crash?

With many tech companies realizing that their expensive urban tech offices are not really needed, what are the community's thoughts on the impact of the housing market in major tech hubs?

Thinking about the house I have right now, it's value is mostly from it's proximity to major tech employers (15 minute commute from 2 major companies), and I'm thinking over what to do now. Is selling now and wait to rebuy during a coming crash a winning move? Or will companies not migrate en-masse to permanent WFH?

Would even a 10% transition to WFH have a significant impact on housing prices? (FWIW I'm in the Seattle area where Amazon and Microsoft prop up much of the housing market.)
