Do I need a License?

It depends on what you do and where you do it. 

Here's a link to the current state licensing requirements:

If you are only working with notes, in most cases you don't need a license, however if you are brokering actual property, the rules are different. 

Always be sure to check current local laws before engaging in business :)
