Kelly Kostecki


An Indiana native, Kelly Kostecki was first drawn to the Lowcountry when she attended the College of Charleston in 2000. The beauty of the area and the diverse culture made it easy for her to develop a deep love for the Holy City.  In 2019, Kelly decided to invest in a beach property of her own in Charleston, and soon after, she decided to call the Lowcountry home, and share her love of real estate as a registered real estate agent.

Through Kelly’s entrepreneurial pursuits, she brings over two decades in sales and marketing, construction/renovation, and real estate investment. She has owned diverse businesses, including a yoga studio, retail boutique, and construction/renovation company. Her love of real estate comes quite naturally, as she grew up in a family business of land development, real estate, and interior design. This upbringing, coupled with her specific experience, affords her the ability to know the ins and outs of real estate first-hand, whether purchasing a forever home, beach getaway, or investment property.

She is also very knowledgeable of the greater Charleston area, including Johns Island, James Island, Downtown Peninsula, Mt. Pleasant, Isle of Palms, and Sullivan’s Island. In her free time, Kelly enjoys kayaking the gorgeous waters around Charleston, hiking on expeditions to some of the world’s top spots, enjoying live music, and traveling both near and far.
