Advice:Do not solicit Mortgage/Real Estate business in CA without a license! You sounded like you were going to work for your brother in-law and that he is a Broker. He should know better. I'd look elsewhere. He isn't paying attention and you will both get in trouble.
In most states, if you are doing talking to people about mortgages with the intent that they do business with you or the company you work for, you need to be licensed.
Another thing, if you are paid for each closing (versus an hourly wage), you would be in violation of federal laws (RESPA).
I think you could do well in sales. Like us, you seem to be weird enough... uh, I mean, personable. If I find your other leg, I'll let you know. Until then, maybe you should get a pair of crutches.
