Michael Collins

When you’ve worked with people for as many years as I have, you tend to learn a few things. Believe it or not, my first lesson came, when I bought my first house. It wasn’t an easy decision with seemingly insignificant details having the potential to turn into huge problems later! The experience and knowledge gained from that experience was just the first stepping stone. I observed that I had found my calling and I wasn’t backing away. A few years down the road, it helped me become a premier real estate expert in Alexandria and the surrounding areas.

Whether you are looking to buy or sell, neither decision should be taken lightly. A house is much more than a place to live. When you walk into your place, it should feel wholly yours. My previous clients will tell you how much that matters to me. With my gift of building strong relationships, I present people with the right home for them.

Currently, I work with buyers and sellers in Arlington, McLean, Old Town Alexandria, Fairfax, and Alexandria. My passion for technological developments has helped me see it wasn’t enough to be good at what I do now. I needed to be one step ahead always. That’s why I went on to validate my expertise by receiving extensive training in the latest real estate strategies.

My passion for helping people meshes perfectly with my choice of career. Please contact me when you are looking for your next home.
