No one will know the answer to your question better than you.
Only you know the demand for homes in your neighborhood. Only you know your price in comparison to the rest, and what makes your home better or worse. Only you know the marketing efforts of your agent and your "projected" selling time.
On the other hand, if you have no idea of what I'm talking about - it's time to get on the phone with your agent. You want them to explain all of this to you.
If all has been done, take a deep breath and be patient.
Best of luck!
