Housing in Mountain Home consists almost entirely of ranch properties and scattered homesites on large acreage across the Hill Country. There are no formal subdivisions; instead, the community's homes sit among working ranches, hunting tracts, and open rangeland. The setting produces an extremely low-density, rural pattern, with properties valued for their land, water, and wildlife as much as for any structure.

Mountain Home has no formal neighborhoods; the community gathers around the post office, store, motel, and church near the road junction, then spreads across miles of ranchland. The Y.O. Ranch, the camps, and the research station are the area's principal institutions, scattered across the countryside. The community's geography is defined by the ranches and hills of northwestern Kerr County rather than by residential streets.

Life in Mountain Home centers on ranching, hunting, and the outdoors. The Y.O. Ranch brings visitors drawn to its exotic game and western heritage, while the summer camps and the Cowboy Camp Meeting mark the community's seasonal rhythms. Residents value the quiet, wide-open setting and the ranching way of life, drawing on nearby Kerrville, Hunt, and Ingram for schools, shopping, and services.

Mountain Home sits along Texas Highway 27 in northwestern Kerr County, connecting it to nearby Hunt and Ingram and on to Kerrville, the county seat, and the larger Hill Country highway network. The community's rural roads wind through ranch country, and its position in the Hill Country places it within reach of the recreational areas around the Guadalupe River and the region's state parks.

Recreation in Mountain Home is tied to the land: hunting, fishing, horseback riding, and ranch life dominate. The Y.O. Ranch's exotic game and working-ranch heritage are a regional draw, and the Texas Catholic Boys Camp and Hill Country Cowboy Camp Meeting bring seasonal activity. The surrounding Hill Country offers creek access, wildlife viewing, and scenic drives through northwestern Kerr County.
