Condominiums are classified as Warrantable, Non-Warrantable or a Condotel. Condos are a single, individually-owned housing unit in a multi-unit building. The condominium owner holds sole title to the unit, but owns land and common property (elevators, halls, roof, stairs, etc.) jointly with other unit owners, and shares the upkeep expenses on the common-property with them. Unit owner pays property taxes only on his or her unit, and may mortgage, rent, or sell it just like any other personal property.
