Aaron Palmer and Mark Marshall work together to provide clients with responsive, hands-on representation.

Together, they offer the experience, market knowledge and personalized guidance needed to successfully buy, sell or expand a commercial real estate portfolio.
Our services extend from initial property evaluations and strategic positioning through marketing, negotiation, due diligence and closing. Whether representing a self-storage owner considering a confidential sale, an investor pursuing an acquisition or a property owner evaluating development potential, our focus is on maximizing value, improving efficiency and delivering a clear path forward.
An integral part of our operation is Ground Floor Properties, our dedicated development arm focused on creating quality housing solutions. Ground Floor Properties responds to the growing need for residential living spaces through thoughtfully planned, community-centered projects. By applying our market knowledge and development experience, we seek to create sustainable, accessible homes that meet high standards for design and functionality.
Together, C21 Commercial Advisors and Ground Floor Properties provide a comprehensive platform combining commercial real estate brokerage, investment insight and responsible development.
