Should I get my RE license?

[Jason Rowlett]

I know that an RE license is not necessary to be an investor but I would like to bid on HUD and invest in different states to expand and diversify my portfolio. Before I invest in taking the courses I'd like to ask...

Does having the license give you a lot more education and credibility as an investor? 

When bidding on HUD, are there advantages to being a licensed agent over a licensed broker or vice versa?

If I don't get my license, what are the best sources to learn RE laws for different states? 

Thank you!
