Rockwall County has never grown accidentally. Its transformation from open pasture to one of the most affluent and supply-constrained counties in North Texas has been shaped by infrastructure decisions, school performance, water planning, bond elections, and a steady eastward push from Dallas. Justin Holland, with 20 years of real estate experience, has built his career inside that structure.
As founder of Legacy & Co. Real Estate in Heath, Texas, Holland operates across residential resale, luxury and lakefront property, land acquisition and disposition, investment housing, new construction, and select commercial assignments. The firm represents a growing roster of agents across Rockwall County and the broader North and East Texas markets, advising clients in one of the state’s most competitive submarkets.
Before launching Legacy & Co., Holland helped scale a brokerage to more than 300 agents, gaining firsthand experience in recruiting, training, operations, and transaction oversight at scale. He also served four terms in the Texas House of Representatives, representing House District 33. During his tenure, he chaired the Sunset Advisory Commission and authored House Bill 1500, the 2023 renewal legislation for the Public Utility Commission and ERCOT following the 2021 winter grid failure. The role required sustained engagement with statewide infrastructure planning, utility governance, regulatory oversight, and fiscal accountability.
Those systems directly influence property value in North Texas. Transmission routes shape development corridors. Municipal utility districts determine long term tax burdens. Bond programs affect school expansion and roadway capacity. Water supply planning determines how far growth can extend. In Rockwall County, where developable land is finite and demand remains strong, these variables are measurable components of pricing and long term appreciation.
Legacy & Co. was formed around people as much as property. Holland established the firm to bring together professionals who value discipline, preparation, and personal accountability over transaction volume alone. Many of the agents who joined were drawn to a culture grounded in steadiness, where integrity and clear communication are expected rather than marketed. The company operates on principles of leadership, loyalty, faith in action, and commitment, shaping both client relationships and internal standards. Legacy & Co. seeks to serve clients who approach real estate as a serious financial decision and long-term asset, not a casual trade.
Through the Cullins family lineage, Holland’s roots in Rockwall and Heath trace back to the late 1800s, reinforcing a long view of land, ownership, and development within a community his family has served for generations.
Rockwall County’s appeal is grounded in proximity and constraint. Lake Ray Hubbard limits outward expansion. Commute patterns tie the region to Dallas while preserving municipal autonomy. Median household income ranks among the highest in Texas. These fundamentals create price resilience, but they demand disciplined growth. Overextension in development or municipal debt can erode value as quickly as a poor pricing strategy.
In one of the fastest-growing counties in Texas, Justin Holland operates at the intersection of land, policy, and capital, positioning clients within a North Texas market where infrastructure, governance, and capital allocation ultimately determine long-term value.
