Even with no activity on your listing, your agent should be in contact with you every two weeks. Perhaps to share some online stats, current market trends, things you could do to improve the home, or even to suggest a price reduction.
If there is no activity on your home, then most likely the agent forgot about you which is a common mistake many agents make. Out of sight, out of mind. Some believe that the listing will not sell, and therefore there is nothing they can do.
Regardless... the move right now is yours. Tell your agent what you expect. If there are plenty of showings and no offers, your agent should tell you what you can do to get that offer. If there are no offers and no showings, then your agent should tell you what you can do.
Bottom line though... I can tell you that if you have nothing for 6 weeks, you are overpriced. Your agent knows that too.
