How long until Seattle has a correction?

[Account Closed]

I plan on selling my duplex in Burien, WA next summer. From the research I've done Seattle shows no signs of slowing down by then. But, I've got a nagging voice in the back of my head saying "don't get greedy, cash out now!" I want to sell into a strong upward trend. I don't want to risk waiting for the top of the market. Any Seattle realtors or investors have an opinion on what we'll see in the next 9 months?
