The brokerage relationship disclosure may be incorporated into the listing agreement, but must not vary from the wording required by the State of Florida. The Realtor you choose should be experienced in marketing and selling homes like yours - the price range, the neighborhood. You want a person who knows your neighborhood, but one who will also be aggressive in marketing and who will have sources of potential buyers from outside the area. The days of just putting it in the MLS and putting up a sign are long gone as an effective means of marketing. Choose an agent who is responsible and responsive, ethical, and who treats real estate as a profession.
Track record is important.
Increasingly, situations arise between contract and closing that require experience and persistence. Be sure to hire an agent who has those. Look at Interview Questions for a Real Estate Agent to Sell Your Home for some questions to ask in the process of choosing an agent. Once you have chosen the agent, you should jointly address the listing price, the expected sale price, the commission rate and the term of the listing. Consider not just the price of the service, but the value of the service.
