The concept of condominium ownership allows for individual ownership within a multiple-unit dwelling, making it the correct choice. In a condominium, each unit is owned individually, while common areas and facilities, such as hallways, elevators, and recreational spaces, are owned collectively by all the unit owners through a homeowners' association (HOA). This structure enables residents to have private ownership of their units, alongside shared management and maintenance responsibilities for the communal areas.
In contrast, a cooperative involves owning shares in a corporation that owns the entire building, meaning residents do not own their individual units directly. A vacation lease typically refers to a rental agreement for a short-term stay and does not confer ownership. A timeshare generally allows for shared ownership of a vacation property but is not same as individual ownership in a multi-unit structure like a condominium.
