[0] Ownership [Condominiums] Just like buying any other property on an individual plot of land, the buyer receives a deed that enables the option to sell outright or sublet the unit. [Cooperatives] 
Members own shares of the corporation that owns the building; the larger the living unit, the more shares owned. Members cannot transfer title or ownership at any point because when they decide to move, ownership transfers back to the corporation.
