I would have to look into that specific neighborhood more in general to give you the best answer...but just off of the basic market conditions...things are taking a while to sell right now. It's not hard to catch all the "bad news" about the national real estate market...and even in Seattle that is leading to slower sales.
Townhomes and condos are being built in large numbers all over the great Seattle region which is really leading to much slower sales than we saw in the past few years. The good news as a potential buyer though is that homes are still appreciating but because there is so much on the market you have a lot of options and more negotiating power than we have seen in recent years.
If you're thinking of buying in that area don't necessarily look past those listings just because they are taking a while. Discuss with your Realtor your concerns and he or she should do more research to make sure that you are getting exactly what you want at a fair price. Just another good reason to work with a hard-working Realtor on your home search...to make sure that your new community and home is researched thoroughly!
Hope that helps direct your thinking.
