I would offer two additional points.
First, expenses aside, how many homes, like yours, have sold during the time yours was on the market?
Second, did your Realtor review these statistics with you and explain the negative impact of long Days On Market (DOM) may have on your net proceeds?
Also, if the property has received showings the Realtor should provide a list of buyers and brokers who have seen the property or inquired about it (sometimes referred to as a "protected client list"). If anyone of those buyers, or their brokers, buys the property, a commission may be due the original listing agent.
Sometimes when sellers initially appear to be motivated to sell, and later, as the market shifts, decide that they do not want to sell, the Realtor is in a tough spot. We invest a great deal of time, energy, and money upfront. The best way to answer your question, assuming the Realtor did a good job, is to ask yourself "What would I expect if I were in the Realtor's shoes"?
