Since the fee to sell your home is very comparable from agent to agent, you need to find the agent who provides the most tools and has the greatest skill set to sell your home most effectively. Typically, it takes more than just a sign in your front yard to sell your home. The best indicator of future performance is past production. The volume of business your real estate agent does in your community certainly means others have gone through the same process you re are going through, and selected certain people. Your agent should be willing to give you the name and number of every client for the previous year and let his or her clients give a personal affidavit.
Some agents close quite a bit of business, but are indifferent to the service they provide.
Ultimately, your Realtor's job is to represent your interests. They will have a fiduciary responsibility to do what is best for you, and not is what is best for them or their company. In effect, you are investing, through a sales commission, in the character of the real estate agent whom you are hiring. After all is said and done, you must trust the agent with whom you list your property for sale.
