Harriet Kaufman
Real Estate Professional
Licensed Assoc. Real Estate Broker
As a long-time Manhattan resident, both living and working in the real estate industry here for more than 30 years, Harriet has an extensive list of successful deals from Greenwich Village to Tribeca, and from the Upper East and West Sides. Her hundreds of buyers and sellers are secure to know they have a broker who thoroughly understands the current market, and upon whom they can rely for honest and sound advice.

Harriet was given Warburg’s prestigious Top Producing Broker recognition in 2009, and has consistently ranked amongst the firm’s Top 10 performers. A fierce negotiator with a hallmark combination of determination, diligence and professionalism, Harriet works tirelessly to see each transaction through to a successful outcome.

Despite financial market woes, Harriet successfully closed on the largest sale south of Columbus Circle in 2008 for a $30 million glass penthouse at 145 Hudson Street. The property was the first of its kind to be built and sold in the Tribeca neighborhood. She is also responsible for sales in many of the City’s finest buildings including The San Remo, The Beresford, 778 Park Avenue, 45 Gramercy Park North, Stella Tower, the iconic Walker Tower, and recently in Harlem at 1890 Adam Clayton Powell Blvd.

Harriet has worked closely with her associate, Nealy Erber, for over 15 years. As a team of two, they provide availability, accessibility, and the management support their clients need throughout the transaction process.

Harriet takes great pride in all of her transactions, no deal is too big or too small. A true testament to Harriet’s success and business ethic are the countless referrals and repeat customers she is so fortunate to work with. She has also had the wonderful opportunity to help generations of families find their new homes.

Growing up in Utica, New York, Harriet always dreamt of living in New York City. Having worked and lived in Manhattan for over 30 years with her husband where they also raised their daughter, who currently lives in Tribeca. Harriet considers herself very lucky to have a job that she loves and one that allows her to assist others in finding their own dream home in New York.

Testimonial from Jakki K.

Last summer, I needed to get my mother a place near me in Park Slope, fast! She had a

month-to-month rental in South Slope, twenty blocks from us, which was taxing for her and for me to drop my baby off for child care. I was working with a great agent, but often, I sent him the leads I found on Street Easy.

 

Then came Joy! Apparently her years of experience in sales take nothing away from her ability in the rental market.

 

Within days, she sent me listings that were within my budget and only a block or two from me.  She reached out to the listing agents, including one agent who pulled her listing off the market within a few minutes of posting it because hundreds of people applied. Joy helped me prep my paperwork and to negotiate in a way that put me ahead of the pack. By the end of that week, my mother had a place on the same street as me, two blocks down.

 

I’m reaching out to Joy for my next home in NYC!

Testimonial from RT

Andrea Wernick made the selling of my co-op a smooth and pleasant experience. She knew exactly what to do at every step of the process and gave excellent guidance.  Andrea and her team marketed the apartment well and showed it often leading to an accepted offer and sale.  Andrea was a pleasure to work with and I would recommend her to anyone looking to sell a NYC co-op.

Testimonial from Susan L.

Dear Susan,

The closing, as you know by now, was successfully completed this afternoon. I just wanted to thank you and Michael for all your help and professionalism in making the sale happen. You were straight and clear with me all through the ups and downs – and your guidance was excellent throughout.

I know you understand that for me this has been bittersweet. But “the team of Susans” worked wonderfully and I am really grateful.

Testimonial from Susan Oh

Susan and Michael, Thank you again! This could not have gone so smoothly without you. Both of you are awesome at what you do and thank you for pulling us through this one at the end.

Testimonial from Allan and Jeff Rothman

Annie Cion Gruenberger was absolutely fantastic to work with. She walked us through the entire process from preparing, decluttering, pricing, working with the building, lawyers all the way through to a terrific sale that we were thrilled with. She was always professional but I now truly feel she is a friend. I will recommend her to all my family and friends in the future.

Testimonial from Jonathan S.

Mihal was a great help in finding an apartment rental. I was relocating from out of state. She walked me through the process and lined up multiple virtual showings, all on short notice. Her videos and knowledge were very helpful in finding me a place I was comfortable with. Even after signing the lease she followed up multiple times to make sure all was well.

1.17.23
Testimonial from Alica E.

Mihal did an outstanding job assisting us with purchasing our co-op. While we were searching she checked in frequently and sent us lots of listings. When we found “the one” she helped us negotiate a competitive offer. She was a tremendous help getting through the co-op approval process. She guided us through every step and was always available when we had questions or concerns. She also connected us with a great mortgage banker and I doubt we could’ve landed such a deal without Mihal’s connection. She is very caring and committed. We really felt we were in good hands with the entire process with Mihal’s knowledge and expertise.

Testimonial from Chiti P. and Bill K.

We used the Gottlieb Team to sell our last apartment and buy our current one. Both experiences were smooth, efficient and thorough from start to finish. Particularly when it came time for the negotiating part, they smartly managed the process — maximizing our expectations — and provided a calming presence when we needed it. Their professionalism, punctuality and persistence set them apart in the real estate market. If we move again, they’ll be our first call.

12.29.22
Testimonial from Kristina L.

Mihal did a fantastic job assisting us with the purchase of our apartment. Her expertise in the neighborhoods of the market was essential in determining the purchase pricing along with the future resale value. Mihal was involved from start to finish. She gave great advice, did lots of virtual tours and was extremely patient when it came to our hectic travel schedules.

12.22.22
Testimonial from J&J Moya

Dear Andrea, 
We wish to thank you for all your efforts in making the sale of our studio apartment at Plaza 400 successful–and pleasant. From start to finish, we appreciated your sincerity, experience, patience, artistic touches and sound advice. Your impeccable attention to details and your gracious style set you apart and above others in your profession. We especially noted that you treated the sale of our small apartment with the same care you handled your larger listings. 

We would also like to compliment your associate Donald M. Toresco. He was always a gentleman ready and willing to help. We wish him a long and successful career in Real Estate.

Coldwell Banker Warburg is fortunate to have you and Donald on their staff. Andrea, we were fortunate to have you as our Broker.
