Good morning, Nelli:
Trulia is a data aggregation site that collects information from many different places. The way to "post a home for sale on Truila" is to get your home listed in one of the places they pull information from. As trulia states: "Data feeds are the most efficient way to submit for sale or rental listings to Trulia. We accept several formats". If you have a full time agent with a Masters degree in Planning with Finance and over two decades of experience, working for you, you will likely do better in negotiations. I'd be pleased to provide that service. If you appreciate this answer, please give it a thumbs up, or if this was the most helpful answer, please say thanks with a best answer click.
