that is a very good question... the cynic in me wants to say nothing but govt salaries. however, these taxes are supposed to go to local infrastructure i.e. local govt, roads pretty much anything the us gov provides. the funny thing is in california we get to write these off on our annual taxes. you should talk to a local tax certified public accountant that is familiar with non us citizen issues. also oregon has a very strong support structure for people in need. In Calififornia we have State taxes based on property values along with consumption tax on comsumer goods such as gas and food. Oregon has no state taxes. Try calling the real estate agent and ask them for references.
