Liberty Township's housing is rural and low-density. The stock includes lakeside homes and bungalows around Mountain Lake—many with patios oriented toward the water—along with country homes, farmhouses, and single-family houses on larger wooded or open lots throughout the township. Development is sparse compared with New Jersey's eastern counties, and most residents own their homes. Buyers are drawn to Liberty for lake access, space, and privacy in a quiet Warren County setting, with the township's hills and open land offering room that is increasingly rare elsewhere in the state.

Life in Liberty Township is quiet, rural, and lakeside. Mountain Lake is the community's centerpiece, supporting swimming, fishing, and boating, with homes and bungalows set along its shores and hillsides for a getaway-like atmosphere. The surrounding farmland, woodland, and country roads keep the pace unhurried, and most residents own their homes on larger lots. Community life is small-scale and close-knit, revolving around the lake, local schools, and seasonal activities. It is a genuinely country way of life, within reach of Hackettstown's shops and services and the outdoor recreation of the Delaware Water Gap.

Liberty Township's public school students attend the Great Meadows Regional School District for elementary and middle grades, with Liberty Elementary School on Mountain Lake Road serving part of the township and additional district campuses in the Great Meadows area. For high school, students are served by Hackettstown High School in neighboring Hackettstown. This regional structure links Liberty with nearby Independence Township and keeps secondary education consolidated at a larger regional school while elementary education stays close to home.

Liberty Township is reached via Warren County's rural road network, with county and township roads connecting to nearby Hackettstown and Blairstown. Interstate 80 lies a short distance to the south, providing the principal route toward Morristown and New York City to the east and the Delaware Water Gap to the west. Most residents rely on private vehicles, and Hackettstown—with its shops, services, and transit connections—serves as the township's nearest commercial hub. The combination of quiet country roads and nearby interstate access gives Liberty both seclusion and regional convenience.

Recreation in Liberty Township centers on Mountain Lake, where residents swim, fish, and boat within their own community. The township's rural roads and open fields support country walking and cycling, and hunting is part of the local culture. Nearby, the Delaware Water Gap National Recreation Area offers hiking, river recreation, and scenic overlooks a short drive away, while Swartswood and other Sussex County lakes add further water access. For a small rural township, the combination of a private-feeling community lake and easy access to the region's larger parks gives Liberty an unusually strong outdoor-recreation base.
