Jen was very patient with us as we looked at many homes in many areas of the Hamptons. When we were confident with the neighborhoods, we could call home, Jen left no stone unturned, enquiring about every listing. Being that Jen knows the area so well she spotted a new listing with water views on a block we desired. She arranged a showing, and a deal was made. Can't thank Jen enough for all her hard work finding us the right home.

We have known Jen since 2015 when she helped us find our first summer rental. After finding us several other homes to rent over the years, Jen was indispensable throughout the process of buying a house this year. We are happy with our purchase and highly recommend Jen to anyone looking to buy, sell or rent a Hamptons home.

I cannot say enough good things about my experience with Jennifer Ponzini. It was a very long and tough process and she was extremely helpful and patient. Her knowledge of Sag Harbor and expertise in the market were extremely beneficial. I took up alot of her time and she was never too busy to call me back, text me and send emails. Most of the time I felt like I was her only client. She is very smart and has great people skills, everyone we dealt with loves her. Bottom line is that Jenn is the best.

Jennifer was a great help in making the transaction work and in following through on all that was necessary to get to the closing. Without her guidance, the deal may not have happened. Highly recommended.

Years ago, I was searching for a home and when I thought I had found the one I was looking for my agent failed not only to get it but to continue guiding me through the process?I just lost interest! This year, my friends referred to Jennifer and she showed me the way to get my dream home. I was in love with one of the first houses I saw but when we made an offer, the house was already being negotiated. I was heartbroken but Jennifer encouraged me to keep looking and we found another one that was a good option. Luckily, the day that we were scheduling the inspection, Jennifer found out that my dream house was in the market again and she acted efficiently to get it for me and my family! Jennifer was always very pleasant, cooperative, responsive and professional throughout the whole process. In the future, I will definitely go back to her and without a doubt, I will refer her to anyone buying or selling a home.

I met Jennifer about a year ago when I was looking to purchase investment properties. Never bought any of the properties she showed me for a variety of reasons some of which resulted from her advise and input. She was always open and honest. Yet she never stopped showing me opportunities. Ultimately showed me a residential property that I showed to a close person in my life and they bought it. I then got to see Jennifer in sale/negotiation/closing mode. Shes the best all around RE broker I know.

We wish we had started our house search with Jennifer Ponzini sooner. When we met her, we were frustrated and tired of looking. Jennifer showed us the perfect house and we had and offer/acceptance in 6 days. She provided us with other house choices that would have made us happy too. She listens, researches and shows you just the type of house you are looking for. Jennifer is over-the-top responsive and if she doesn't know an answer, she'll get back to you within hours. Her time is all yours and she is with you every step of the way. She lives locally and knows the community. She is professional (her real estate law degree was useful) and confidential. You will be happy you called her.

Selling this home was very emotional for my husband and me. Jennifer showed compassion, patience and a clear understanding of our expectations. She made the whole process as comfortable and smooth as you would hope. Jennifer advised us of our choices and did not apply any pressure to make a decision.
