Hillside Estates is a large, established condominium community situated off Route 102 in Derry's East Derry area. The development is composed of multiple low-rise buildings spread across landscaped and wooded common grounds. Public FHA documentation identifies 264 residential units in 11 buildings, making Hillside Estates one of the larger condominium communities in the town.

Construction dates to 1972, and the buildings are generally garden-style residences with brick and wood-frame construction. Public records show individual buildings containing multiple units, with unit sizes and layouts varying throughout the complex. The older construction gives Hillside Estates a mature neighborhood character, while the multi-building layout creates a community environment more typical of a large apartment-style condominium than a townhouse development.

Hillside Estates has a comparatively extensive shared amenity package. Public listings identify an in-ground swimming pool, clubhouse, tennis courts, basketball courts, playground, recreation facilities, common grounds, and storage. Association fees have historically covered substantial operating expenses, including heat, hot water, landscaping, plowing, water, sewer, trash, and recreation.

The community is positioned for convenient access to Route 102, Interstate 93, shopping, restaurants, schools, medical facilities, and employment centers. Its Derry location provides practical commuting access toward Manchester, Londonderry, Salem, and southern New Hampshire, while nearby trails and recreational areas add outdoor options. Hillside Estates is particularly suited to buyers seeking amenity-rich condominium living without the scale or cost of a newer resort-style development.
