If you are trying to post a For Sale By Owner property on here, you can't. Trulia only posts properties listed in the MLS. If you have a Realor, ask them to post your property on here once they've listed it in the MLS.
Agreed that if you are posting a "listing" on Trulia as a rental or for sale by owner.
This is not the correct forum for your effort. Trulia pulls data from third party sites. This information has already been verified by the source site as its legitimacy.
If you are trying to post an address of a property that you are interested in buying or renting, then you can include this info within the confines of your question.
In this case, ask your question to the general forum and expect answers related to your question.
Hope that this information is helpful to you.
