I LOVE Seattle! Though research and folks I talk to say it's expensive to live there. Maybe I'm getting the wrong info!
I pay $1850 a month for a 496 sq ft "Open" one bedroom. It's basically a studio with a wall that segments off my bedroom.
Which is more than fine for me :D Get to live downtown, get to walk to work, walk to bars, etc. But if you wanted an average 3br/2ba apartment, you're probably looking in the $3500+/mo. And buying is so competitive right now it's insane.
