Housing in Nemo is rural and sparse, consisting of scattered single-family homes, ranch houses, and acreage tracts rather than subdivisions. The surrounding Somervell County land supports ranching and small agricultural holdings, and many properties include several acres of cedar-and-oak hill country. Newer custom homes and barndominiums have joined older farmhouses as the area has grown in appeal to buyers seeking Hill Country-style space within reach of Glen Rose and the Fort Worth area.

Nemo has no formal neighborhoods; homes are dispersed along Farm Roads 199 and 200 and the surrounding county roads. The community's center is its historic crossroads, marked by the school site and churches. Glen Rose, a short drive west, provides the area's commercial and civic core, while Rainbow, another small Somervell County community, lies nearby. Granbury, on Lake Granbury, is the nearest larger town.

Life in Nemo is quiet and land-centered. Residents enjoy the cedar-and-oak countryside, ranching, and easy access to the Brazos and Paluxy rivers. Weekends often involve trips to Glen Rose for its courthouse square, shops, and festivals, or to Dinosaur Valley State Park for hiking and river access. Community life is informal, centered on churches, the charter school, and the small volunteer institutions of rural Somervell County.

Nemo is served by Glen Rose Independent School District, which covers most of Somervell County and includes the unincorporated communities of Nemo and Rainbow, with its single high school in Glen Rose. The Brazos River Charter School also operates a campus in Nemo, offering an alternative public option. For higher education, residents are within reach of Tarleton State University in Stephenville and community colleges in the region.

Nemo sits at the intersection of Farm Roads 199 and 200 in eastern Somervell County, a short drive from State Highway 67 and U.S. Highway 67 corridors. Glen Rose is minutes away, and the Fort Worth area is reached via U.S. 67 and Interstate 20, roughly an hour to the northeast. Driving is essential, and regional air service is available through Dallas–Fort Worth International Airport.

Nemo's recreation centers on the rivers and hills around it. Dinosaur Valley State Park, minutes away near Glen Rose, preserves genuine dinosaur trackways along the Paluxy River and offers hiking, swimming, and river wading. The Brazos River provides fishing and paddling, and the surrounding Somervell County countryside offers hunting and rural exploration. Lake Granbury, to the north, adds boating and lakeside recreation, while Glen Rose hosts the area's cultural events.
