I just got my license and I am also going to be investing. I am also a Yacht Broker.
In my process of interviewing RE. Rockets to work with I was very open about what I was doing and my goals. That way there are no misunderstandings.
Like everything in life, in every Real Estate office there are those who work full time, those that work part-time, and those that work some times. They already have a mix bag of people.
Think of it as this being your business (which it is!), you are not looking for a place to work as much as you are looking for a company to partner with in your journey to success. Who is going to coach you and mentor you, who provides the most advanced tools for customer interaction and lead generation, who will be invested in your success. Also do you like the people you are meeting in the office is very important.
One of the companies I interviewed even told me that as long as I did a company sale first, I could do two sales for my personal investing without any commission requirements. Not a bad deal!
Hope this helps you in your journey. If you would like to discuss more you can PM me.
Best of luck and success!
