Apartments: A complete apartment building is owned by a company or a person. In almost all the cases. this is your property. What the owners of the apartments generally do is they manage the place and give out apartments on rent. they also take care of the maintenance of the apartments, most of the times. On the other hand, in a condo, each unit or dwelling is owned by one single individual. It is like ownership of a home, but in a shared building rather than a single family home on a plot. A few condo owners choose to live elsewhere and rent out their condo to others and they become your Owner. In fact, that is what some people do.
