Hello Connie. Trulia is not a place where you can list properties as a FSBO. Trulia is a search engine that receives property information from various sources. Anybody who wants to post a property on Trulia has to verify that they are a licensed real estate professional in good standing. Here's what it what you'll see when you try to post a property on Trulia.
Trulia's Single Listing Upload tool is intended as a Licensed Agent tool only. If you are a homeowner who would like your home listed on Trulia (so you can promote your home to more potential buyers), we suggest you email your agent with details on how they can upload your home to Trulia."
I hope this helps. Good luck to you with the sale of your home.
