For legal advice you should seek the opinion of an attorney.
The following information is from the Florida Statutes, Chapter 475. This can be found at: http://www.leg.state.fl.us/STATUTES/index.cfm?App_mode=Displ
475.011 Exemptions.--This part does not apply to:
Any individual, corporation, partnership, trust, joint venture, or other entity which sells, exchanges, or leases its own real property; however, this exemption shall not be available if and to the extent that an agent, employee, or independent contractor paid a commission or other compensation strictly on a transactional basis is employed to make sales, exchanges, or leases to or with customers in the ordinary course of an owner's business of selling, exchanging, or leasing real property to the public.
475.42 Violations and penalties
a) A person may not operate as a broker or sales associate without being the holder of a valid and current active license therefor. Any person who violates this paragraph commits a felony of the third degree, punishable as provided in s. 775.082 or s. 775.083, or, if a corporation, as provided in s. 775.083.
I would ask why you do not want to use someone that does this sort of thing all the time?
It sounds like you are not in the area that your property is located. If that is the case you will need someone that can run credit and background checks. Someone familiar with the Fair Housing Laws. Someone that that knows which disclosures are required for your property and someone that can fill out a lease agreement properly.
