Lic. Real Estate Broker
Thank you for visiting my profile. My name is Sep Niakan, Managing Broker of Blackbook Properties and a real estate sales top producer in the Miami area for the past 15 years.

I pride myself on keeping the buying and selling process simple and fun, being a knowledgeable guide for my clients, and negotiating to get my clients what they want at a fair price.

I have built my business based on long-term relationships, not individual transactions. If a trusted relationship is what you are looking for when buying or selling your home, please give me a ring and let's talk.

On a more personal note, I am married to a beautiful woman, have two beautiful young children and enjoy a life filled with lots of family and friends that I cherish. When I am not working, my only regular hobby is spending time with my family and close friends. I occasionally need to get away for a few days to clear my mind, and my favorite destinations are places where neither the people nor the landscapes remind me of home, so that it can feel I am getting a true "reboot".

Oh, and I am also founder of condoblackbook.com

Lic. Real Estate Associate
Originally from Mexico, Katia is now well known and beloved in the Edgewater and Wynwood communities of Miami. She first gained notoriety as a master baker before she transitioned to real estate.

Stephanie Bienstock stephsobere@gmail.com
(786) 301-5218
Director of Luxury Sales
A true Miami Beach native, Stephanie was inspired at the tender age of 16 to become involved in the transformation of the city. Her ability to get along with everyone and instantly put people at ease made her a perfect fit for real estate. Starting as an assistant to a number of top-line producers of the time, she obtained her license at 19 years old. And, there’s been no looking back ever since.

Stephanie continued working for some of the top real estate minds of the city and gained experience working with affluent clients. This led her to finally begin selling real estate independently in the early 2000s. Since then, her exclusive focus has been luxury waterfront properties, and she has participated in the sale of over $350,000,000 in sales. A feat that has helped many discerning clients find their picture-perfect property on the water.

Stephanie is often described as an open, easy going and genuine person. Being a perfectionist, she loves being organized and well-prepared. This comes in handy for her clients, as she not only brings a sense of structure to their entire experience but also helps put things into perspective for others, giving them the clarity they need to make good decisions.

Besides striving to excel at everything she does, Stephanie loves exercising and a good cup of coffee. She’s a dedicated mom of two and wife of one who really takes enjoyment in spending time with them. Not many know that this perfectionist has ninja-fast reflexes and also packs a mean punch. So spar with her at your own risk.
