Sean was thorough and communicative. He made me feel heard. He was able to see the true value of my unique property and found a wonderful family to appreciate it. I would certainly work with Sean again.

Sean Zimmerman is extremely knowledgable about Ulster county and its real estate landscape. He provided me with valuable guidance on how to prepare my house for sale and how to price it. He gave highly personalized advice tailored to the unique aspects of the property I was selling. In Sean I experienced a high level of professional integrity along with a refreshing low-pressure style, while keeping us on schedule. I felt comfortable throughout the entire selling process.

Weve bought, sold, and built a fair number of houses and worked with quite a few brokers. Sean stands out as the very best, in every category. Incredibly patient, thorough, helpful and professional in all our dealings with him. He is also quite knowledgeable about construction and mechanicals, and on more than one occasion he saved us big bucks. Equally important, hes just a pleasure to work with and we always looked forward to seeing him when hunting for our next home, which he helped us buy recently. We couldnt recommend him more highly and moving forward, would never consider using anyone else!

Hiring Sean to represent me on the rental of my home proved to be the best decision I could have made. His pricing was spot on and we had a well qualified renter in record time. His communication skills are second to none and he was always available to go the extra mile. I would recommend Sean to sellers, buyers, landlords and renters. Give him a call. You will be glad you did.
