Hi Annie!
Depending on what you're looking for, you could also check out one of the local coworking spaces throughout Seattle to give you a stepping-stone between working from home and renting your own office. Sometimes these arrangements can work out really well for folks who are not quite yet ready to be locked into a lease but really need to be in a more professional environment. You can check out what is available at http://wiki.coworking.com/CoworkingSeattle.
Best of luck!!
