This is a very delicate situation. You have a signed listing agreement with a Realtor, and from your last post there appears to be some information that you need to have in order to make the best decision. You might want to consider talking with the Realtor's BROKER after considering the information you have been receiving.
First, the real estate market, like any market is dynamic. That means that it is always changing. New listings come on the market, older listings either sell, reduce price, change incentives, or expire. That means that the market 120 days ago, is not the same market as today.
Second, the Comparable Market Analysis is an ANALISYS OF THE MARKET. That means that your Realtor is supposed to help you understand what the market is like, in terms that you can understand. That also means that because the market is always changing, you needed an UPDATED MARKET ANALYSIS weekly.
Example. I had a listing, we reviewed the CMA and my client and I agreed to price the home UNDER MARKET, so we listed it at $599,000. I thought for sure it would sell for maybe $615,000. After two weeks on the market, with showings by no offers, another property, two blocks down the street, that was nicer, was listed for $599,000. I discussed this development with my client, we immediately reduced the price to $569,000, we had an accepted offer shortly thereafter.
The biggest factor you need to be aware of I asked in my response. How many homes, like yours, have SOLD since your's hit the market? If the answer is ANY, then you need to look at those homes. The homes that sell the fastest are perceived by the buyer, and their Realtor, to offer the most value.
I use a checklist of 20 things that a seller can do to enhance value for their property. Things over which the SELLER has complete contro. The Realtor's job is to EXPOSE the property to the market. It is the seller's job to follow the advice of the Realtor to make the home as attractive as possible (meaning have the best value).
As I stated earlier, I recommend talking with the Realtor's Broker immediately to review your situation. Based on your posts I do not believe your circumstances are going to improve without some action.
Good luck. Keep us posted.
