In the ever-changing world of real estate, finding a trustworthy guide can feel like the pursuit of a lifetime. Buyers and sellers alike are often overwhelmed by the endless options, each promising to be the key to their dream home or the best sale. The complexity of the process can leave even the savviest individuals feeling lost and frustrated.

Picture yourself selling your home or finding the perfect new property without a reliable expert. The stress of missed opportunities, potential pitfalls, and endless paperwork can turn what should be an exciting journey into a daunting ordeal. This is where the value of a dedicated, knowledgeable real estate agent reveals itself.

Enter Maggi Kelly Costello, a beacon of excellence in Colorado real estate. As an Associate Broker at LIV Sotheby’s International Realty, Maggi combines her extensive experience and passion to ensure each client’s journey is seamless and rewarding. Her authenticity and heartfelt dedication prove that selflessness beats self-interest, even at the highest echelons of real estate.

Real estate roots and relocation

Maggi’s roots trace back to Wisconsin, where she grew up before relocating to Colorado over 25 years ago. This move began her diverse career path, starting with a role at a high-end retail firm, where she honed her proficiency in catering to people’s needs.

“While working with Nordstrom, I was so blessed to have instilled the customer service mentality I have carried with me through my career journey,” she recalls. Maggi’s degree in Interior Design and her experience as a business owner of two coffee shops in Denver further enriched her understanding of creating welcoming spaces.

The ensuing transition into real estate was seamless, driven by a genuine interest in helping clients find a home that harmonizes with their lifestyle. Representing the Boulder County, Breckenridge, and Summit County areas, Maggi’s expertise benefits a wide range of clients. In 2024, her professional prowess was vindicated when she was named the Quarter Best for LIV Sotheby’s in Q1.

Building a business through bonds

Maggi’s approach to real estate is deeply personal. “Creating an experience and building relationships is what brings me the most joy,” she says.

Whether working with new homebuyers or seasoned sellers, the Global Real Estate Professional is committed to going over and above for her clients. Her philosophy is simple yet profound: careful listening with a genuine interest in her others’ needs.

Her personal life is as vibrant as her professional one. Married to Michael Costello, a skilled custom home builder, Maggi’s life is a blend of professional synergy and personal fulfillment.

Together, they have embarked on a new chapter, expanding their real estate and design business in Breckenridge and Summit County. This collaboration is more than a business venture; it represents passion, innovation, and partnership. “We aim to create unparalleled living spaces that harmonize exceptional design and craftsmanship,” Maggi explains.

Faith, fitness, and family

No discussion of Maggi’s continuing success is complete without mentioning her Christian faith, which she describes as her cornerstone. Her faith  has guided her through various life stages, including raising four children as a single mother. “God has answered so many prayers,” she says, emphasizing faith as critical to her success and resilience.

Fitness is another pillar of Maggi’s life. An avid triathlete, cyclist, ultra runner, and bodybuilder in the past, she now enjoys fitness for the sheer joy of it. This passion parallels her approach to real estate: disciplined, committed, and driven by love.

Centered on service

Philanthropy pervades beyond Maggi’s professional and personal life. She donates a portion of each transaction to The Association for The Recovery of Children, an organization with a resonant aim: rescuing children from exploitation. This commitment to giving back underscores her belief in making a positive impact in every possible way.

In Maggi’s words: “Each transaction is a blessing to me, a relationship, an experience that is a gift.” This perspective, coupled with her extensive knowledge of the real estate market and a keen eye for design, makes Maggi a standout professional. Her journey is a testament to the power of tenacity, faith, and altruism. Buying, selling, building—each is a vital component of the tangible real estate world. Maggi Kelly Costello hits those heights while aiming higher; she harnesses values that transcend a transaction and evoke its transformational quality in buyers, sellers, and beyond. Her story is a reminder that being the best real estate agent in Colorado is about building lasting relationships and making dreams a reality.
