Trulia does not currently syndicate listings, but you can learn about submitting your listings by clicking on the link below. You can use one of our partner sites if you'd like to syndicate your listings. We list both rentals and for-sale properties.
If you are a for sale by owner, Trulia does not allow the post, you can however, try blogging about about your property--if and when you do list with an agent, he/she can post it for you--just ask--or--consider any flat fee realty company that feeds into MLS and Trulia.
I don't believe that is possible at this time. Home listings can be posted for sale on Trulia by real estate professionals, but I don't believe that you can use Trulia to post on the MLS. Contact a real estate professional in your area if you would like to list your home for sale and get it listed on the MLS.
