This is a common phone call I receive as a Realtor. When a home buyer signs a builder's contract they are locked in as per the terms in the agreement. A Florida Real Estate Attorney should have read it over for clarity prior to signing. Because a home buyer has also gone alone to the Builder, the Builder will not allow even any verbal input from me as a realtor. I would not be able to speak to the sales team in any way throughout the process. As a Realtor the Brokerage representation would be included in the purchase agreement.
