Niki from Trulia here. Trulia is a search engine for residential real estate listings that are indexed from agent/broker web pages. Our service is free, and there is no charge to have listings posted on Trulia. At this time we do not add For Sale By Owner listings. Your profile shows you as a "Home Owner" if you are in fact a real estate professional, or are listing your home "for rent" as a landlord, you may go to your profile and edit the type to reflect your status.
Once your profile is set up for a real estate professional you will see a page called "My Listings". You can edit your listing by logging in to Trulia, hover your mouse pointer over your name in the top right corner of the page. The site navigation menu will appear as a drop down menu, click on "my listings". Once in the listings page choose the "for rent" tab. Your property will appear with an "edit property" button. You may add pictures to your listing here.
Thank you for using Trulia for all of your real estate needs.
