In AZ (and most states), licensed RE Brokers are the only parties legally allowed to earn and be paid a commission for bringing buyers and sellers together.
Even licensed agents must be paid through the Broker.
The only finder's fee that can be paid an unlicensed person is in the form of rental credit in the event a tenant refers a renter to a property in which they also rent.
It's not about whether Brokers want to, or will agree to pay you.
It's illegal to practice real estate without a license. In AZ, a Class 3 or 6 Felony (depending on if you are also advertising your 'services')
If you are good at bringing buyers and sellers together, you could always take your licensing courses, pass your tests, get licensed, pay the fees, dues and expenses we have to and continue your education for the rest of your life as we must, so you could earn those fees.
I know lots of 'referral agents' who do just that. Lots of them work in 'high public contact' professions in our area (service, resort etc) and as long as they hang their license under a Broker, we are absolutely happy to compensate them for their contribution to the transaction which is basically turning us on to a prospect and nothing beyond.
The management of the transaction, coordinating with the dozens of experts and professionals we have to in order to protect our clients, and taking the liability for that client is all on the Broker.
Nice work if you can get it! :)
