Overview
Situated on Sioux City’s east side, the property is listed under NC-4 zoning. The total lot size is 0.2 acres, and the property size is reported as 1,584 square feet.
For tenants or owner-operators looking for a manageable residential income property, the unit mix provides variety within one building, including both a larger 2-bedroom layout and smaller options. The listing also notes utility responsibilities: the owner pays water, sewer, and trash for all units, and electric for unit 3. This configuration may simplify budgeting while allowing each unit’s living space to function independently.
