Welcome to Washington. In a quick look at current available rentals, I didn't find too many right now. I would suggest you contact a local agent or two to discuss your plans and have one start to send you new rental listings as they come available. You can also watch Craigslist and other sites to see what you can find.
A tool I refer people to all the time regarding schools is the Washington State School Report Card. You can breakdown and compare districts and individual schools as how they perform on standardized testing in different subjects. I've included a link for your convenience.
