LHR,
You're 100% correct--local housing prices are so far out of whack from the median income that it's not even funny.
I live 0.8mi from the Red West campus of MS, so I guess I am living in the Inner Circle, the Golden Triangle, Pink Pony Central, AKA Ardell's favorite neighborhood.
Median income in Redmond (home of Microsoft, Nintendo, and a whole host of other hi-tech companies) from the last census was $69K, which I'm also guessing is close to what a lot of MS employees make. Median housing prices in this area (around MS, not the city as a whole)--around $700K (1970s split-level for $500K, 3500sf McCrackerbox for $1M). So you can get into a house for somewhere between 7-14x median income for the area. Hmmm. Does that sound affordable to you?
And you're right about the commute--I reverse-commute northbound 405 from Kirkland up to Bothell (then east to Monroe) every morning, and I am so thankful that I'm not sitting on the other side of the divider! Renting is a far preferable 'hell' to sitting in traffic for two hours a day.
