 The ownership benefits of a CID are having rights to an undivided interest in common areas and amenities which might prove to be too expensive to be solely owned.For example, an owner would like to have a pool but cannot afford one.When buying a condominium with a pool in a CID of one hundred units, an owner would have use of that pool for basically one-hundredth the cost due to sharing the cost with the other 99 owners.
