Jan sorry for talking about you in the third person. You can advertise on your blog through trulia also try Kijiji.com and Craigslist. http://www.fizber.com/ has a good format but doesn't get that many hits. There are many other site that I advertise through but most don't allow FSBO's, so search using free FSBO listing and see what pops up.
If you choose to use a realtor at a later date please view my blog about how to choose one: http://www.trulia.com/blog/david_chamberlain/2008/12/how_to_ there is also a great Idea for an open house on my blog.
Rockin, Thanks for kepping the balance.
If you are not going to use an agent please contact a real estate lawyer it can be very affordable to have one provide or look over your contracts.
Jan get in touch with a local mortgage broker as most buyers are not approved for a loan and realy don't know what they can afford. When you get a buyer you can call your mortgage broker to pre-approve them before you write a contract. http://www.floridadreamloans.com/AreYouPre-Approved
I am sorry for your situation. If you really need to sell, even Trulia, as great as it is, it not THE answer. The truth is that in order to sell a home in this economy, it takes professional selling skills.
Let me ask you...If I interviewed with you to sell your home, and I had YOUR track record at selling homes, would you hire me? Meaning would you hire you? Of course not.
So, I recommend a few suggestions:
First, try to sell on your own if you want. On average only about 10% of homes sold are sold without professional representation.
Second, just in case, interview a couple of agents, compare their proposals, then if you need Plan B, you can jump right in.
The biggest problem you have (no offense) is that you do not know what you are doing. My dad said "Confidence is the feeling you have right before you truly understand the situation".
But don't take my word for it. If you would like to interview a top Realtor, I might be able to refer to you one.
