Unfortunately, Trulia is specifically geared to provide agents another marketing tool, but not available to folks selling their home FSBO. For what it is worth, though, an agent can capitalize on this, and market your home, not only through Trulia, but through a large variety of other outlets too. Many of these other outlets are perused by potential buyers, but again are not available to FSBO sellers.
I know you have heard this several times already, but I would be happy to help you with the sale of your home. The difference is, I would be willing to assist you with some direction on how you can market it FSBO, if that is what you prefer. There is nothing flowery or mysterious about my offer to help. I will simply be a resource for you, if you prefer to not take advantage of my skills in listing/selling your home.
Feel free to contact me.
