Rental management contracts

[Cassandra Hood]

I have a question. Is it common for the rental management company to state in the management contract that if I, the owner of the home, decide to sell my home within a year of termination of my rental management contract I have to pay the realty management company 6 1/2% commission fee of the amount I sell my home for even if I use a different company. Is this standard. My home is in Florida.
