• Entire property (vs. individual units): when you rent the whole property (e.g., a house, villa, or entire apartment) and not just a part of it, such as a private or shared room. This is an essential distinction on platforms because it changes guest expectations, the type of privacy offered, and often the applicable local regulations. If you manage multiple units in the same building (e.g., separate apartments), you can choose whether to rent them individually or as a single property.

It is essential to identify and contact the relevant authorities to obtain all necessary licenses, permissions, and registrations.
