Hello Homar: We began loading to Trulia over a year ago through our Broker. Now Prudential loads ALL of their Listings throughout the entire USA, to Trulia. Many aother Real Esrtae Brokerages in the USA have agreements now in place do load their listings to Trulia. I do not know about individual properties.

Homar, I believe Trulia receives it's listings through a "push" from a brokerage, or from a REALTOR who has signed up, to put their listings on the site. I don't think it's open to the public, unless it's through a real estate brokerage.
Homar, if you mean posting on Trulia, you can do that either through a realtor or through vflyer. Check the FAQ, and they will direct you if you are a FSBO. Please feel free to contact me directly as well - and all the best,
