It sounds to me as though you should discuss your plans with a Realtor that knows three things:
1. Your personal situation (when you want to move, why you want to move, and your possible alternatives)
2. Your local market trends
3. Your property
Unfortunately, I don't think any of the posters, although very well-intentioned, know these three key things. My recommendation is to speak with a few top Realtors in Lynnwood and ask them a lot of questions to figure out your possible options and the costs, pros, and cons, of each.
I do not work in your area however I would be happy to refer a top agent that does. You can contact me via my Trulia profile or call me 1-888-284-2056.
As my dad always said, measure twice, cut once.
