How do I get the money owed to me from a small claims suit? I was awarded the rest of my rental deposit and they have not paid me.

Unless the law in Washington is different from the jurisdictions in which I practice, you can garnish any regular income they receive, e.g. rents.  You can also cause their assets to be sold at auction to pay the judgment.  The procedures for accomplishing these collection methods differ by state, so you may have to do some research, but they are available.
