"Joanne is great broker - professional, experienced, patient and down-to-earth. She worked with me for over year through the highs and lows of my apartment search and I could not wish for a better guide in Manhattan's real estate market. Joanne combines a great commercial grasp of the market, which helps one find the best value, with intricate knowledge of multiple factors that pave the path to closing, from board package to understanding the renovation process." - A. Zaslavsky (Buyer)

"Joanne was wonderful. She really knows the NY market and the laws etc. regarding co-op purchases and sales. She negotiated with the Co-op board and handled the massive amount of documents etc. that they required. She was tireless in her pursuit of the right buyer for our unit, and in her efforts to make sure the deal went through. If I ever have a future real estate need in NYC Joanne is the person I will use as my real estate professional." - D. Herzog (Seller)

"I worked with Joanne to purchase an apartment. I can't say enough about how great she was in the search process, the negotiation and the closing. She was right by my side with wit and expertise to match. I really enjoyed working with her and I was very lucky to find her." - E. Mason (Buyer)

"Never before have we encountered a realtor who is so attentive to the needs and concerns of her client. While representing the landlord’s interests, she was always responsive to our needs and made us feel that they were important in the process as well. She diligently took notes, followed up immediately on questions or concerns we had and promptly kept us up to date along the way. We will not hesitate to recommend you to both tenants and landlords as a top notch realtor." - Janeen T. & Shari H

"I am writing this to recommend Nina Hausner whom my husband and I recently engaged for the sale of our apartment. We spoke to different agents and never felt as comfortable with them as we felt with her. She was unfailingly courteous, honest and available. Nina presented various options to best position our property and was always open to discussion. Most importantly, we always felt that she was always working on our behalf. The apartment sold quickly and with no disruption to us and at what we deemed a very fair price. We both highly recommend having Nina as your real estate broker." - Yvette R

"The wonderful Nina Hausner helped us through the "finding an NYC-apartment"-challenge and my husband and I were so grateful for her hard work and commitment. Several weeks before we met Nina, we tried it ourselves and often felt so overwhelmed by the craziness of the NYC apartment market. When we started working with Nina, she was very well prepared and really considered our wishes for an apartment in the Chelsea neighborhood. As I work mostly from home I needed good light and with our budget it didn't seem so easy, but Nina did it! As we applied for a rental in a coop building, we had a ton of paperwork to collect and Nina guided us perfectly through the process and answered all our questions quickly. I recommend Nina Hausner highly! She is kind, friendly and very good in what she is doing! It was a pleasure and blessing meeting her and in the future I would work with her again." - Katharina W

"Christine was phenomenal! She helped us find a beautiful three bedroom apartment in one of the most competitive areas in Manhattan. Prior to working with her we were overwhelmed by the number of options and by how fast everything was being taken off the market. Christine provided us with photos and video of 5 apartments that met all our criteria. She scheduled visits for our favorites and helped us seal the deal on the ones we liked best. She even helped us negotiate the rent down so it was more inline with the market price for the area." - S. Attia (Renter)
