The concept of multifamily refers to a residential complex with more than one housing unit in the same building. Despite being a residential property, multifamily is a category of commercial property in which all units (or apartments) are intended for rent and registered under a single registration. Therefore, the complex has a single owner, and all residents are tenants.

This concept of the real estate market is already well-established in the North American real estate market. In addition to the industry's support, many banks and private and public companies are fully dedicated to this type of property.

One in eight people in the United States lives in a property ranked as multifamily, and the total already exceeds the mark of 40 million people.

Within this concept of assets, there are still three aspects present in the United States, they are:

- High-Rise: Most are exclusively based in urban centers and consist of large buildings with more than five floors.

- Mid-Rise: These are developments with less than five floors outside urban centers.

-Suburban/Garden Style: They are 2 to 3-story buildings in the suburbs.

Among the main advantages of multifamily, the low volatility is worth mentioning: short-term rentals (which allow for immediate adjustment to market conditions) and primary post-investment passive income.
