Hi Amanda,
Welcome to BP. As for your question if I understand it correctly is: should you get your Real Estate Salesperson License to work at a Real Estate agency in Brooklyn to make more money?
It sounds like you already have a well paying job if you're able to save some money and handle you expenses. A real estate license is useful for investors who want access to MLS and feel that it can be an advantage. It's certainly not necessary but it can give you a bit of an edge.
If you're thinking you can get licensed and start doing rentals or sales to supplement your income, I can tell you that it's WAY harder than you think. If you're thinking of being a part-time agent please consider the following. Real estate anywhere in NYC is very competitive. It's difficult for agents who are full-time to be successful and it would be even more difficult for someone who is just part-time. Scheduling viewings and showings to work around your spare time is going to be a challenge. Unless you have an endless stream of people you know personally that are going to be your loyal customers then you working with new customers is going to be your biggest challenge. Customers do not sit around and wait for agents. If you don't have the time to show them what they want to see when they want to see it, they will simply find someone else. And in this business it's all about keeping your customers happy and being available when they need you.
I guess the short answer is. If you don't plan on being a full-time agent, it is not worth getting your RE License. I would never advise someone to be a part-time agent. To me Real Estate is more like a lifestyle than a job.
