As far as I can tell, he has been a broker for 4 months with no prior CA real estate sales license.
Wow, so in CA you can have a broker's license without one transaction under your belt as an agent? I'm living in the wrong state! In Ohio you have to have a certain amount of transactions as an agent(I believe 40 or so, or 80 "halves" representing only the buyer or only the seller), and I believe at least 2 years of having a valid agent's license, plus another 2 years min. of a college education. I have been focusing on my agent's license and getting ready so I'm not 100% on the numbers but I know the requirement is there.
To add to the topic here, in Ohio that add would be illegal. It is illegal to give anything over $50 for a referral. I am not sure about rebates, but $500 part of the ad is 100% referral reward. Like most areas I need to dig deeper about rebates.
Honestly, I didn't know there could be a difference between a rebate or a referral fee in this type of situation.
