DeCordova's housing stock is defined by its origins as a planned lake community: gated neighborhoods of single-family homes developed from the late 1960s onward, many on golf-course or lakefront lots, with newer sections such as DeCordova Ranch adding contemporary construction. Homes range from established mid-century and 1970s-era residences to larger custom and newer builds, reflecting the community's evolution from weekend getaway to year-round suburb. The resort-style, amenity-rich layout gives the housing market a distinctive, self-contained character within Hood County.

DeCordova is organized around its central amenities rather than a traditional downtown. DeCordova Bend Estates, the original late-1960s development, forms the community's core along Lake Granbury, while DeCordova Ranch represents newer phases with parks, trails, and greenbelts. The gated entry, golf course, marina, and clubhouse tie the neighborhoods together, and the community's planned street network and lakefront parcels give it a cohesive, resort-oriented feel distinct from the surrounding countryside.

Life in DeCordova centers on Lake Granbury and the community's resort-style amenities. Residents enjoy the golf course, marina, and clubhouse, along with boating, fishing, and waterfront recreation, all within a secure, gated setting. The planned community fosters an active, social atmosphere, while nearby Granbury provides a historic downtown square, shopping, dining, and healthcare a short drive away. The community suits both full-time residents and those seeking a second-home lake lifestyle within reach of the Dallas-Fort Worth area.

DeCordova is served by the Granbury Independent School District, which is based in nearby Granbury and serves the eastern Hood County cities of DeCordova and Stockton Bend, along with Granbury itself. The district operates elementary, middle, and high school campuses in Granbury, and students in DeCordova attend Granbury ISD schools a short drive away. The district is the public school system for the greater Granbury lake community.

DeCordova sits about six miles east-southeast of Granbury, the Hood County seat, and is reached via local roads off the U.S. Highway 377 corridor through Granbury. The city lies roughly an hour southwest of Fort Worth, placing it within commuting range of the western Dallas-Fort Worth metroplex. Travel is car-based, with Dallas-Fort Worth International Airport the nearest major commercial airport, and the community's gated, self-contained design means most daily amenities are internal.

Lake Granbury is the centerpiece of recreation in DeCordova, offering boating, fishing, waterskiing, and waterfront living on the Brazos River reservoir. Within the community, the golf course, marina, and clubhouse provide year-round recreation, and neighborhood parks, walking trails, and greenbelts support an active lifestyle. Nearby Granbury adds a historic downtown square, public boat ramps, and additional parks, making the broader lake region a hub for outdoor activity in North Texas.
