It is important for individuals looking to purchase real estate in the United States—especially foreign investors—to thoroughly evaluate the legal and financial implications of these two systems before proceeding with a purchase.

In the United States, particularly in large cities like New York, there are two primary systems for the ownership of apartment units: the condominium ("condo") and the cooperative ("co-op").
Both systems allow individuals to reside in and acquire apartment units. However, they differ significantly in terms of the legal nature of ownership, purchasing procedures, conditions for sale, and management structures.

The condominium system is a model of ownership that is quite similar to the "condominium ownership" (kat mülkiyeti) system in Türkiye.
Under this system, an individual becomes the direct legal owner of the apartment they purchase. Ownership of the apartment is registered in the buyer's name. In addition, the owner also holds a specific share of ownership in the common areas within the building.

The apartment is purchased independently, and ownership is transferred to the buyer.
The apartment owner may sell, rent out, or bequeath their property.
Common expenses, as determined by the building management, must be paid.
Owners contribute to the maintenance and operating costs of common areas.
Rental and sales transactions are generally subject to fewer restrictions compared to a co-op system.

The co-op system features a structure that differs from conventional real estate ownership.
In this model, the entire building is owned by a company known as a "Cooperative Corporation." An individual purchasing an apartment does not acquire the title deed to the unit itself; instead, they purchase a specific number of shares in the corporation that owns the building.
These shares come with a "proprietary lease"—an agreement that grants the individual the right to occupy a specific apartment within the building.

The entire building is owned by a corporation.
The buyer purchases shares in the corporation, rather than the apartment itself.
These shares are linked to the right to occupy a specific apartment.
Monthly maintenance and operating expenses must be paid.
New buyers may be subject to approval by the board of directors.
There may be various restrictions regarding the renting out or resale of the apartment.

The spread of the co-op system—particularly in New York—is rooted in the concept of collective ownership and the desire for greater control over building management.
In this system, residents are not merely occupants of individual apartments; they are also shareholders in the corporation that owns the building.
This structure allows boards of directors to evaluate the financial qualifications of prospective residents and, under certain circumstances, to reject applications.

May require that a certain amount of cash reserves be maintained.
May conduct an interview with the buyer.
May impose restrictions regarding leasing and resale.

The condo system offers greater flexibility regarding ownership and disposal rights. Consequently, it is generally more advantageous for individuals looking to invest in real estate, rent out the property, or sell it in the future.
The co-op system, on the other hand, may be a preferred choice for those intending to reside in a property for the long term and who are comfortable with a collective management approach within the building.
In some markets, the purchase price of co-op units may be lower than that of comparable condo units. However, management restrictions, financing terms, and monthly maintenance costs must be carefully considered when making a purchasing decision.

In the United States, "condo" (condominium) and "co-op" (cooperative) systems represent two distinct models of ownership and management for apartment-style living.
In a condo system, an individual directly owns their specific unit, whereas in a co-op system, the individual becomes a shareholder in the corporation that owns the building, thereby gaining the right to occupy a specific unit.
The differences between these two models extend beyond the form of ownership; they also impact the processes of purchasing, financing, leasing, selling, and management.
Therefore, it is essential for those looking to purchase real estate in the United States—especially foreign investors—to thoroughly evaluate the legal and financial implications of both systems before making a purchase.
