Generally, retail properties, industrial buildings, and residential dwellings have only one or two tenants that are bound in long-term rental agreements.
On the contrary, multifamily real estate properties, such as mobile home parks, RV parks and resorts, and apartments, can have dozens of tenants locked in diversely-structured rental agreements, which eventually minimize the risk of vacancy during hard economic times.
However, there is no denying that the risk of vacancy is always present. Yet, if you manage vigilantly, it will limit the vacancies to less than 10%.
