Do you have a relationship with a Real Estate Consultant at this time? If not, go ahead and interview one to three now and ask them to provide you with a written recommendation. You do have options. Not all agents are willing to work out fee based services and flexible commission structures. Some are. Any recommendations should include market opportunities, comparable sales, other condos for sale, trends, and net proceed projections. Subject to future plans and opportunities, you could consider a short sale. Don't just assume that the lowest commission company is your best option because your money is tight. That is very limiting.
If you already have a relationship and you have a potential game plan with option A, B, or C, Then you are far farther ahead of the game than most consumers today.
