I plan on looking at a boat about 3 hours away and out of state later in the week. I'm in Washington and the Boat is in Oregon. Oregon has no sales tax. I'm buying the boat from a private sale. He has the all the paperwork for the boat and trailer. I plan on taking a bill of sale with me. Anything else that I need to know or take with me to close on the boat deal? I don't want to make 2 trips to have the guy sign more paperwork.
