County courthouse a good place to start. Ask if there any rezoning/building permits in for land anywhere nears yours...might see if there's a long-term plan for growth in the area...see how that impacts you. Property closes by either a title company or an attorney depending on which state you're in. Check and see what WA is and find a reputable person who'll represent you to close the deal. Buy a book on 1st time land buying...preferably specific to WA state...best $10 I ever spent years ago...you'll be amazed at the simple things you can do that are free...well worth the money. Good luck!
