""Justine is amazing! With such a daunting task ahead of me, I relied on her experience and advice to help me navigate the challenges of buying my first apartment. She was attentive, accessible, and answered all my nervous questions with patience and kindness. She listened to my need/want/dream items, put things in perspective, and kept my search on track. Once I found my new home, she had a recommendation for everything I needed to move forward. From the first tour to the closing, she was there to help each step of the way. I was lucky enough to be introduced to Justine by a friend, and now I'm happy to return that favor by recommending her to everyone looking to purchase in New York City!""

"I've had the pleasure and good financial fortune to work with Justine Masters over the past 10 years - from initially being my agent for the purchase of a great UWS Condo, to helping me rent out the condo over the past 5 years, and finally selling my condo in December 2025. Justine is an extremely knowledgeable real estate agent who takes the time to fully understand her client's needs and preferences, extremely patient with exceptional communication skills. She is an excellent negotiator for her clients. One particular example that highlights all these attributes was during the sale of my condo in 2024. Justine was able to successfully negotiate a deal that was over $100k from what I was expecting and also helped facilitate closing a few open permits that should have been closed in 2014 during the gut renovation of my condo. I would strongly recommend Justine to anyone looking for a professional realtor who will be with you during the entire process and protect all your financial needs and personal preferences."

"I had the pleasure of working with Justine Masters twice, once as a buyer's agent for my first home and then again as a seller's agent for a family property. As a buyer's agent for my first home, she was organized and personable and took seriously my needs and questions as a first-time buyer. Two years later, when my family was preparing to sell our grandparents' home, Justine was the natural choice. She had my family's best interests at heart throughout the emotional process of selling my grandparents' home and helped us navigate complicated state and city housing codes to ensure everything went according to plan. Justine is an expert at what she does. She patiently communicated with us at every step of the process; she anticipated our questions, helped us problem solve at what felt like roadblocks, and ultimately negotiated a deal worth $125k more than we expected. If you are looking to buy or sell a home in the NYC area, Justine is the person to work with. If you are deciding between agents, choose Justine. I hope to have the pleasure of working with her again."
