Get to Know Mark Duncan

I am eager and willing to work with anyone with a pressing real estate need, large or small. My 20+ years in the business provides me with the know how to get the job done and alleviate the stress created through a normal transaction.

I enjoy working with 1st time buyers, families and investors of all levels as that is what makes my career so interesting. My referral worthy state of mind  has created in me a range of marketing ideas and philosophies designed to Wow every client at every juncture.

I am also an ASA, or Accreditted Senior Agent, which is a nationally recognized earned designation providing me with a unique insight into working with the mature buyers and sellers of today. Review to understand more of what I bring to the table.

Please feel free to call or note me with any questions you have as a fellow realtor in another market place or as a potential client looking for straight answers on today's complex world of real estate.


I moved to Burlington some years ago as it is a wonderful city offering all the amenities of a much larger one but that does not mean I am limited to Burlington. In fact, my first 12 years of being a full time realtor was in Peel (Mississauga & Brampton) and the western GTA.

I spread my time these days across all these points of interest and pride myself on knowing more about more neighbourhoods than the average Realtor so if you or someone you know needs help from the 427 to Hamilton, Dundas & Ancaster & around the Lake to Stoney Creek. Going north, I can provide you with guidance in Milton, Brampton and the outlying towns. I will always be up front with you, answer your questions on the spot or find the answers you are seeking very quickly.

Call me to help because I am eager and anxious to help....I will tell it to you straight and not pressure you along the way.

“Janet and I want to thank you for helping us to find our new home. As “out-of-towners” moving into a new area, it was great the way you helped us to identify what was available and quickly set-up some viewings the very afternoon that we walked into your office. Your professionalism, dedication and response to our needs, and willingness to meet “whenever” were greatly appreciated. You made the whole process easy and painless. We will (and have already!) heartily recommend your services. Many thanks!”

“Searching for our first house in an area that we didn't know well was a daunting task. We had a lot of questions not only about the houses, but about the entire process of buying a house. Mark was very patient and knowledgeable about the whole process and made sure we understood what it took to buy a house in our market of choice. Nat and I would recommend Mark to anyone who is looking for a responsive Realtor who will work hard for you to get you the house you desire.”

““I am a second time client of Mark Duncan’s and both times have had a very favorable experience; he made the buying and selling of my property effortless and stress-free for me. Mark is both personable and professional; he’s always available when you need him and responds to messages in a timely manner. I could definitely trust Mark with his knowledge of the real estate market and found that his advice was always prudent. I would definitely recommend Mark to my family and friends for their professional realtor needs.”
