Gastiaburo + Stella
The Percent for Art Team

For nearly four decades, Karen Gastiaburo has been making an indelible mark on the New York real estate industry. Since she first discovered her knack of matching people with properties, Karen has come to know the city’s marketplace inside and out. Drawing on her years of experience and the communication skills she developed as an actor, Karen ensures exceptional customer service for all of her clients. As a yoga and meditation teacher, she calmly guides her clients through the twists and turns of the sales process.

A longtime resident of the Upper West Side, Karen now lives in Harlem where she is a proud homeowner in a neighborhood she loves for its close-knit community, diverse restaurants, and lively art and music culture. She dedicates a generous amount of time to community initiatives in the arts and healthy living.

Karen has closed many residential sales in neighborhoods across the city and as a sales director managed the launch of two Tribeca real estate offices. She is a NYRS Designee, having received the Real Estate Board of New York’s premier professional residential real estate credential. She is an active member of REBNY and served on the committee for Deal of the Year, an annual REBNY Gala, and REBNY’s Ethics Committee, as well as several terms as Co-Chair of the Downtown Committee, where she was instrumental in facilitating harmonious relations among industry firms.

Along with Leanne Stella, Karen is part of Gastiaburo & Stella, The Percent for Art Team.

“I have known Karen for over 15 years, having purchased at least half a dozen investment properties in Manhattan. On every single occasion we ended up buying either the first or second property that she had picked for me! She always knew what my needs were and took the time to listen and understand what I was looking for. When describing Karen, words that come to mind include: intuitive, knowledgeable, informed, dedicated, and above all, an amazing person. Karen’s skills and talents as a realtor are unparalleled.” – Indira K.
"Karen is an amazing real estate broker -- warm, personal, patient, and accommodating. During the most stressful time of my life -- selling a home of 30+ years, Karen's mastery made this challenge to a rewarding experience. Karen has a thorough understanding of the real estate market, including the complexities of NYC coops, is thoughtful and responsive and listens to her clients' needs. All in all, Karen was a pleasure to work with, I recommend her wholeheartedly." - Tina I.
“Karen was a godsend. My husband and I were first-time buyers in New York City; we didn’t know the first thing about becoming homeowners. Karen walked us through the entire process from beginning to end and was there for us the whole way, with knowledge and understanding. When we had questions, she had answers. When we needed resources, she connected us to them. She is calm, kind, competent, and has her act together. We ended up buying a co-op, and the board remarked to us how well put-together our package was! All thanks to Karen. We were in such good hands, and for that we are grateful and want to sing her praises to others!” – Kim B.
"We were not looking forward to the exhausting ordeal that searching for and buying an apartment in New York City can be. Because of Karen Gastiaburo we were spared firsthand knowledge of that experience. A distinguishing feature of Karen's is her network and resources. We took full advantage of the people and options she had at her fingertips. We were able to leave parts of the process with her team while we attended to a family crisis. Everything went much better than we could have hoped for thanks to Karen." – Luis C.
"I have known Karen for a very long time [but] I live in New Jersey. I was looking for a home and working with a realtor for many, many months and I felt that this person was just not listening to me or answering my questions. Out of desperation, I called Karen for advice. She found me a realtor in Hoboken at the Halstead office: Maria Oblow, who listened to me. Within a month, I found a beautiful apartment in a fabulous building. I could not be happier. Even if you don't live in the borough of Manhattan, you can rely on Gastiaburo and Stella to find you the absolute perfect person to work with. They prevented me from making the worst mistake of my life and found me someone that was amazing; I am so grateful!" – Kimberly W.
