"Sondra WuDunn is an outstanding and professional real estate agent. From our first meeting, she provided insightful recommendations to help us properly market our rental property from what minor repairs would enhance the apartment and an overview of the local market and strategic comps. When we ran into some challenges with our condo management group, Sondra was patient, helpful, and had a strong can-do attitude. Throughout the process, Sondra was a great listener and very organized with both prospective tenants. Sondra came up with creative approaches to market the rental property during the COVID pandemic and was able to find several solid tenants within a short period of time." – Gladys C., Upper East Side, NYC

“After searching for a Manhattan pied-a-terre for a while, a friend recommended that we reach out to Sondra. With Sondra’s assistance, we found the apartment we’d been dreaming about. As with so many New York real estate transactions, things were a bit complicated: a stringent co-op board application, protracted negotiations with an overseas seller, and a process we were quite unfamiliar with as out-of-state buyers. Sondra navigated it all with patience, grace, and an unflagging attention to detail which is mandatory with co-op sales. She was definitely a calming influence during the inevitable stressful moments, while buoying us with her positive attitude and energy. We would recommend Sondra without hesitation to anyone in the market to buy or sell in New York City. We also feel that Sondra is now a friend!” – Karen M. and Greg L., Boston, MA

"My wife and I have known Sondra WuDunn for ten years, first as a landlord, and then, starting a few years ago, as our real estate broker. In both situations, Sondra has been a dream to work with. She is highly organized and hardworking. When we were in the market for a co-op, she walked us through the process so that everything was clear, and helped us get our paperwork together quickly to present to the sellers. As the sellers changed their terms and requested more information, she represented us with a staggering amount of patience and professionalism, returning phone calls immediately, picking up documents at odd hours, and never appearing ruffled or fatigued. We highly recommend Sondra to anyone who wishes to buy or sell a property." – Dan S., Upper West Side, NYC

"Sondra was knowledgeable, hard-working and professional. More importantly, she listened. She took the time to understand what we were looking for and quickly set us up with the perfect rental. We highly recommend Sondra if you’re looking for a dedicated real estate broker in New York City." - Kathy and Michael M., Irvine, CA

"Thank you, Sondra, for helping us find the perfect pied-de-terre in Manhattan!

Sondra is extremely knowledgeable about the New York real estate market. She was quick at understanding our family’s needs, very diligent and prompt in following up on our queries with potential sellers, and so efficient in guiding us through New York’s complicated closing procedure despite us being 8,000 miles away in Hong Kong! Sondra organized the most comprehensive apartment viewings for us via WhatsApp. Her attention to detail and her professionalism made the entire process of purchasing an apartment remotely fun and stress-free. My husband and I are most grateful to Sondra and we look forward to meeting her in person one day soon. We would recommend Sondra to be your real estate advisor any time!" – Sheron Y. and Don R., Hong Kong
