Justin Underwood
Owner/Broker

Immediately after high school, Justin enlisted in the United States Air Force where he served for 20 years in a Civil Engineering Squadron. During his service, he developed the leadership, operational discipline, and problem-solving skills that would later shape his approach to business. Justin ultimately retired from the 188th Wing in Fort Smith, Arkansas, concluding a career built on teamwork, accountability, and mission-focused execution.
While serving in the military, Justin began building a foundation in business and leadership, earning a degree in Organizational Management from John Brown University. This education, combined with his military experience, helped shape his philosophy of building organizations through strong systems, empowered teams, and aligned partnerships.
Following his military retirement, Justin focused his efforts on entrepreneurship and real estate. Recognizing the long-term potential of recurring revenue businesses tied to real estate ownership, he began building and acquiring residential property management companies operating under the Real Property Management franchise system.
Through disciplined growth, strategic partnerships, and a focus on operational excellence, Justin has helped expand a multi-market property management platform responsible for managing thousands of residential units across several states. His long-term vision is to continue scaling the platform to manage between 7,500 and 10,000 doors while creating opportunities for partners and operators to grow alongside the business.
In addition to property management, Justin has been involved in real estate development, construction, and long-term rental property ownership. His investment philosophy centers on building durable assets that produce reliable income and long-term value.
Justin strongly believes that the best businesses are built with great people. He has intentionally structured partnerships that allow talented operators to share in both the profits and growth of the companies they help build. This approach allows the organization to scale while maintaining a culture of ownership and accountability.
Looking ahead, Justin’s long-term goal is to continue growing the property management platform while gradually transitioning from day-to-day operations into a more strategic leadership role. By building strong teams and aligned partnerships, he aims to create an organization that continues to grow while allowing him greater freedom to focus on family, travel, and new investment opportunities.
