Commercial Real Estate is commonly considered to be all real estate with the potential to generate outside income and/or revenue for the owner of the real property. This can include many property types: office buildings, retail properties, apartment units, condominiums and even raw land. If the property has the potential to generate revenue now or in the future it may be deemed as commercial real estate. Alternatively, some people consider those properties that generate outside income and/or revenue, except for real estate that is habitable (houses, condos, apartment buildings), to be commercial real estate.
