Trulia listings are restricted to realtors only however there are some great website FSBO
Create a site for you home at: http://www.epropertysites.com/
Then list it on the FSBO sites with a link to your site.
Why use a Realtor instead of going it alone or going with a discount brokerage?
A full-service Realtor throws out a larger net. The discount broker is going to do just enough to service your account. Unless you have the time, you won't match the resources a Realtor has at their disposal. Some of Realtors have worked years building a network of prospective buyers and sellers. The agent's individual influence is important.
If you could see what we see when we study a neighborhood, you would wonder why people go it alone. I come across plenty of properties that were obviously priced with no perception of what was going on in the market. The FSBO either prices too high or too low.
Talk with a local Realtor. It can't hurt.
Let me know if I can be of help.
