Answer:
subdivision
Explanation:
A real property subdivision takes place when a real property (parcel of land, house, etc.) is divided into smaller areas. The whole idea behind a subdivision is that it should be easier to sell the property in smaller parts.
When a subdivision is carried out on a condominium, the physical space is not divided, rather the property time is divided into time share units. In this case, a person can purchase the right to use that condominium during 3 weeks each year.
