@Thanh Vu Here are the list of States which offer total reciprocity with Ohio licensees. 

Here is a link on the Real Estate Commissions website.http://www.mass.gov/ocabr/licensee/dpl-boards/re/faqs.html#n005

Refer your client to a local buyers agent and have the buyers agent track down the listings and listing agents.We can assist with this and we offer a 25% referral fee to licensees on all closed deals.

The Georgia Secretary of State, Georgia Real Estate Commission, Licensure and Brokerage, states the following: 520-1-.07, Management Responsibilities of Real Estate Firms(e) In order to provide reasonable guidelines for licensees and their support personnel, but without defining every permitted or prohibited activity, the Commission has identified the following tasks that unlicensed support personnel under the direct supervision of a licensee affiliated with a broker can perform:1. answering the phone and forward calls to a licensee;2. submitting data on listings to a multiple listing service;3. checking on the status of loan commitments after a contract has been negotiated;4. assembling documents for closings;5. securing documents that are public information from the courthouse and other sourcesavailable to the public;6. having keys made for company listings and installing or removing lock boxes from company listings;7. writing advertisements and promotional materials for the approval of the licensee and supervising broker;8. placing advertisements in magazines, newspapers, and other media as directed by the supervising broker;9. receiving, recording, and depositing earnest money, security deposits, and advance rents;10. typing contract forms as directed by the licensee and the supervising broker;11. monitoring personnel files and license reports from the Commission;12. computing commission checks;13. placing signs on property and removing such signs;14. ordering items of routine repair as directed by a licensee;15. acting as courier for such purposes as delivering documents or picking up keys [the licensee remains responsible for assuring delivery of contracts and closing documents as required by O.C.G.A.

To your second part -- If he encouraged a seller to list it as low as possible, then that is when it would become unethical, I would think, and the fiduciary duty is being tampered with.It seems the most logical thing to do would be to disclose he's a licensee in the original purchase contract, close on the property, then close with your end investor.

If you are merely looking for deals for your own account, don't advertise the fact that you are a licensee.

I'm pretty active here in BP, and I also know every one or our licensees personally.  

Can't say for sure about Texas, but in California what you are proposing would amount to "practicing real estate sales without a license" which is not allowed, and paying a finders fee or kickback to a non-licensee is also not allowed.

To make matters worse, they are licensees and can receive further sanctions and/or be fined.

I don't represent clients and haven't in many years but there is no legal issue with assigning a contract as a licensee as long as your broker allows it and you fully disclose your intent and your licensee status to the seller.
