Bill, If homes like yours are selling in the area, for some reason yours is not competitive. It may be because of location, price, features, floor plan, curb appeal or a thousand other reasons. Talk to your agent. What do they say? How are they marketing your home? Who is showing your home? How are the homes that are selling being marketed and by whom?
If homes like yours are NOT selling in your area, be patient. In a slow market there are no magic answers, but remember, it only takes one happy buyer to sell your home. If you can't be patient, lower the price and keep lowering the price until it becomes such a good deal a buyer can't pass it up. Don't blame your agent for the slow market or for the lowering prices; they do not control the market. Believe me, they want your home sold.
