About Mark

Welcome to the Mark Seiden Real Estate Team, voted the best Real Estate Office in 2023 according to Westchester Magazine. As one of the top ten out of over 12,000 agents in our Multiple Listing Service for over 20 straight years and being one of the top two Teams in Westchester and Putnam Counties, we certainly sold and continue to market a large number of properties for sale. And that clearly is the result of our efforts for our clients.

But, those “sales and signs” mean more than just marketing houses for sale or selling a buyer a home. After all, any Realtor® can do that! All of our clients are, or were, going through major life transitions each and every day during every transaction. And selling or purchasing a house is probably the biggest transaction that one undergoes.

We strive to listen to and understand our clients’ unique situations. We want to know their hopes, dreams and even fears. We feel privileged to share in the most important moments of our clients’ lives. We guide people through their transition in life as everyone needs help during change.

We appreciate their faith in us and strive to create an experience for them that is authentic and honest. As you navigate on our site, you’ll learn more about the uniqueness of our team of agents as well as our preferred mortgage brokers. You’ll gain a better understanding of how we represent you, our client. You’ll have the ability to search the MLS, obtain information about the surrounding area, learn about our client appreciation events and so much more!
