Co-op versus condo: What is different and why is it important?

To understand the disparity between the size of condominiums and cooperatives, it is important to know the difference between the two. A condo looks a lot like an apartment. Where they are different is the property: an apartment is rented while a condo is owned. However, both are typically managed by a real estate firm and often share common spaces and amenities in a larger building.
