Lic. Real Estate Broker
Thank you for visiting my profile. My name is Sep Niakan, Managing Broker of HB Roswell Realty a real estate sales top producer in the Miami area for the past 10 years.

I take satisfaction in being an informational resource to help you make the right decisions and negotiate the best outcomes when it comes to real estate. Having been published in the Miami Herald, Inman, MarketWatch by Dow Jones, Inc, and many other regional and national publications proves that I have an obsession with knowing where the market is and where it is going.

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 recently married and have a beautiful baby boy, a dog older than anyone's great grandmother and 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".

And if you happen to still be reading and want to know more......I have also been part of a number of local real estate boards, including Miami Realtor Association's Residential Board of Governors and National Association of Hispanic Real Estate Professionals South Florida Chapter. I also founded CondoBlackBook.com, the leading Miami Condo informational resource.

Client Care Coordinator
Hello Everyone, I’m Amanda - most likely the first voice you will hear when reaching out to HB Roswell Realty. Caring for our valued clientele is my #1 Priority.

I enjoy listening to people and determining how to best assist them on their real estate journey. Having worked as a client intake coordinator for a family law firm and a foreclosure counselor for a non-profit, I am experienced at helping others during times of change. As exciting as buying or selling a home can be, it can also be riddled with anxiety. What is our home worth? Where do we go once we get that offer? And most important, who do we trust to guide us on this journey?

I assure you that our talented team of professionals will remove the uncertainty and replace it with a joyful and positive experience. Born and raised in Syracuse, New York, I have also lived in North Carolina and Georgia and have spent a short time out west in California. In addition to client intake and counseling, my background includes title insurance and closing coordination.

In my spare time, I love taking my precious Coonhound-mix for walks or hitting the gym. In the past, I have enjoyed volunteering as an ESL instructor and am now looking for a new opportunity to give back. If you are entertaining the thought of selling your home or are curious to see what sparkling gems can be found in Miami’s dynamic real estate market, I am a phone call away. I look forward to connecting you to the city’s #1 Boutique Real Estate Team. HB Roswell Realty has Miami’s most passionate, knowledgeable and dedicated real estate experts…..all we are missing is YOU!
