One of the common misconceptions is that "we've got plenty of time". Time to try it on our own, time to try to rent it out, etc.
Do you remember when the mortgage meltdown occured in September of last year? No one was anticipating that happeningm it just did. And the effects have been staggering.
So my advice to you is this:
Talk with a Realtor that knows your property, your personal situation, and the market. Ask them questions and get enough information so you can figure out your options. One of the challenges with Trulia is that people post questions that truthfully we really cannot answer because we don't know the three things I mentioned above.
Is your market going up, down, or sideways? I just had a conversation with a client yesterday and she wants to sell and move out of state. I showed her the market statistics and she replied that she is considering "waiting until next year when the market improves". I explained that based on the market trends, which are downward, did she really believe tha the market was going to improve? So in the end I asked her this question: if you knew beyond reasonable doubt that to sell your home for the highest price meant listing it now, or waiting perhaps four or five years, what would you do? She replied she'd sell now.
You could be in the same boat. Because you don't know exactly what the market is doing right now, you do not have the facts to make an informed decision.
