Legality of a Loan Brokerage Name

[NaDean Bowles]

My real estate business name is Ruby Homes.  I have an amazing logo and want to build brand recognition.  I'm starting to hand people cards and they say, "Hey, I saw this at XYZ."  :)  It makes me happy.  

I am also a commercial loan broker. While I already have the business, I want to switch it to a DBA with something that connects the two. I want to do something like Ruby Financial or Ruby Lending, etc. but my mentor, who admittedly knows nothing of loan brokering, thinks the SEC will come down on me if I make it anything that could be construed as something else such as a financial adviser or if the two are too closely connected.

Has anyone dealt with this issue before?  Does anyone have name suggestions?   

Thank you!
