I believe you can on Zillow.
If you are going FSBO, I would suggest focusing on FSBO websites in regard of marketing your home. There are many of them. You can make a Google search with the following keywords for instance "advertising FSBO home".
I have pasted the results in the Web References below for your convenience.
These are tough time to be going it alone in a real estate initiative. The reality is, regardless of working with or without the support od a real estate professional you are still going to have to compete with short sales, foreclosures and other appropriately priced property.
At this time Trulia is recognizing only property listed on the local MLS by a real edtate professioanl.
I don't think so...
Have you thought about listing your home with a Realtor?
We most often see you will save time and money by using a realtor.

According to last info I saw, Trulia is still only accepting listings that have some sort of agent representation.
