That's a load of crap. If you want to be in real estate, be in real estate. Who generally hears about the deal first? Who is out there networking looking for deals? Who is out there talking with people all day about real estate? Who has more education, knowledge, and experience in real estate?
I don't know who gave you that advice but they are not well informed. You are liable no matter what. If you are selling your own property and say the wrong thing to a potential buyer, you can still be sued. The difference of having a license is you are educated on what those liabilities most commonly are. Hence, you know not to say them or can rephrase into a different way.
Are licensees held to a different standard? Yes. But it is because you are educated. It is no different than an attorney being held to a different standard in court. You cannot be dishonest in your dealings. But in my 15 years of RE, negotiating with sellers and buyers, I have never had the occasion to be dishonest. I just call it as it is. Tell the truth.
I think you should get your license and go work for a firm that specializes in Multifamily. You will have more opportunity and get in sooner on deals. This will also allow you to do syndication as well.
My 2 cents.
