More about Don Koonce

I fell in love with the real estate industry after buying and remodeling two homes. My partner and I could often be spotted at open houses, even though we were not in the market for a home. Real estate gives me the opportunity to work with a wide variety of people and properties. From first-time home buyers, investors, or the family looking for their forever home, each transaction allows me to build relationships with amazing individuals from all aspects of life. It’s not a job when you love what you do! I am patient, hardworking, detail-oriented, and loyal with a passion for helping people. My goal is to meet and exceed my client’s home buying and selling expectations, making each experience a pleasant one, as well as an experience that they will want to share with their family, friends, and loved ones. I began my career in the construction industry, learning from my dad, who was a ...

Don Koonce

    • Don was fantastic to work with! My husband and I bought our first home with Don as our agent and the process could not have gone smoother. He is knowledgeable in the construction of homes and was able to point out potential issues in the houses we saw. Don stayed on top of market activity for every home we showed interest in. He is incredibly patient and always quick to respond - by text, email, or phone call. He answered all of our first-time buyer questions, he helped us at our signing meeting, and even helped me set up cable for our new tenants! Don always went above and beyond to help us and we would highly recommend him if you're looking for a new home

      - Elaine Chang, Seattle, WA
    • Don was a pleasure to work with and brought a wealth of local knowledge and solid advice. We were looking for a property with the potential for doing our own improvements (basement build-out, etc.) and his background and knowledge of building and remodeling were extremely valuable. During the several-month period we spent looking at house after house, he was patient and responsive to our needs. And once we chose a property, he expertly guided us through the process. Since the home we chose was being listed through the seller's relocation company, we had a more complex landscape to negotiate involving the seller, relo company, listing agent, as well as our own lender that we chose to go with. Don was a complete professional and we even got feedback from our out-of-state lender saying how smoothly things went. I wouldn't hesitate to recommend Don to anyone looking to buy or sell in the Seattle area.

    • Don helped us purchase our fist home. He is disarmingly friendly and down-to-earth. He quickly picked up on what we were looking for, organized a good tour, and helped us close a good deal on the perfect condo for us. Don was timely and responsive in his communication. He gave us frank advice when we needed it. He also went out of his way to help us with things beyond his duties (ex. recommendations for water heaters, lock smiths, general moving advice, etc). He was a pleasure to work with!

      - Victoria Nelson, Seattle, WA
    • My wife and I cannot speak highly enough of Don's endless patience, optimism, and honesty! Don helped us buy our first home after over a year of looking in a difficult Seattle real estate climate. Don was always available at the drop of a hat for consultation, home viewings, or pretty much anything else we asked of him. He has a deep knowledge of the entire home buying process as well as what to look out for in and around a property. When we finally found a home that we knew was the one Don went to bat for us, got us a great deal, and made the closing process as painless as possible. We are deeply thankful for the help and time that Don put in to help us buy our first home. We would recommend Don's services to anyone looking to purchase in the Puget Sound area!
