Our Clients Testimonials
Melissa J.
I worked with Diana Lipsig to both sell my home and purchase a new one, and I couldn’t have asked for a better experience.
When selling my home, she was extremely helpful in advising what needed to be done to get the best possible price. Her guidance was clear, practical, and realistic — and she didn’t just make suggestions, she helped me actually get things done. That support made the whole process much smoother and led to a great result.
On the buying side, she was very low pressure and incredibly patient. She took the time to really understand what I was looking for and made sure I ended up with exactly what I wanted. I never felt rushed or pushed into a decision, which I truly appreciated.
Overall, she was professional, knowledgeable, and genuinely had my best interests in mind. I would highly recommend her to anyone looking to sell or buy a home.,
Melissa R.
I highly recommend working with Diana Lipsig!
She helped me sell my NYC COOP while I was out of state, and made the process very smooth. She kept me updated on open houses and potential leads. She also communicated well with my tenant at the time. She was knowledgeable about the neighborhood/building, and also proactive in finding answers for potential buyers.
As a first-time seller, Diana was very patient and explained the process step by step. She was warm, welcoming, and detailed oriented. She turned a typically stressful experience into a very straightforward process!
Alicia & Mark
From the moment we connected with Randall Property Group, we knew we were in great hands.
As first-time buyers in a fast-moving NYC market, we were overwhelmed-- but our agent made everything clear, explained every step of the process, and was by our side through every showing and offer. Within just a few weeks, we found the perfect condo in Brooklyn, and they negotiated an incredible deal.
Their responsiveness and deep local expertise made all the difference. We couldn’t be happier in our new home!
Jonathan R.
Selling our townhouse in Long Island felt like a daunting task, but the team at Randall Property Group turned it into an incredibly smooth experience. They crafted a smart marketing strategy that highlighted our home’s best features, and within days of listing it, we received multiple offers --ultimately selling for well above our asking price.
What stood out most was their strategic thinking and constant communication. They truly care about their clients and deliver results.
Sophie L.
Our relocation from out of state to NYC could have been stressful, but Randall Property Group made it easy.
They took the time to understand our lifestyle needs and budget, then curated a thoughtful selection of neighborhoods and properties that matched what we were looking for. We felt supported from the first call through closing, even with our limited availability for in-person visits.
Their professionalism and attention to detail made all the difference -- we’re thrilled with our new Manhattan apartment!
