Multi family properties: Meaning, Criticisms & Real-World Uses

What Are Multi Family Properties?

Multi family properties refer to residential buildings that contain multiple separate housing units within a single structure or complex. As a significant segment of Real Estate Investing, this asset class offers investors the opportunity to generate rental income from multiple tenants simultaneously⁹⁹, ¹⁰⁰. These properties can range from duplexes and triplexes to large apartment complexes, each designed to accommodate more than one household⁹⁷, ⁹⁸. Each unit within a multi family property typically has its own distinct living space, including a separate kitchen and bathroom facilities, while potentially sharing common areas like hallways or laundry facilities⁹⁵, ⁹⁶.

History and Origin

The concept of multi family housing in the United States traces its roots to the early 19th century, driven by urbanization and the Industrial Revolution. As populations grew in cities, the demand for affordable and efficient housing led to the development of buildings that could house multiple families⁹³, ⁹⁴. These early multi family properties were often referred to as tenements, particularly in urban centers like New York City, where they were built quickly and often characterized by crowded and unsanitary conditions⁹¹, ⁹².

A significant development occurred in the mid-1800s with the construction of early apartment buildings, which offered improvements over traditional tenements, such as private bathrooms and kitchens⁸⁹, ⁹⁰. The Lower East Side Tenement Museum in New York City, a National Trust Historic Site, stands as a testament to this era, preserving buildings like 97 Orchard Street, which housed thousands of immigrant families from 1863 onward⁸⁷, ⁸⁸. This museum showcases the evolution of multi family living and the experiences of the working-class and immigrant families who resided in these structures⁸⁵, ⁸⁶. The 20th century saw a major boom in multi family real estate construction, spurred by population growth and the increasing availability of credit, making them a popular option for both renters and investors across the country⁸⁴.

Formula and Calculation

The valuation of a multi family property often employs the Income Approach, which relies heavily on the property's income-generating potential⁷². A core metric in this approach is the Net Operating Income (NOI), which represents the annual income generated by the property after deducting all operating expenses, but before accounting for Debt Service or taxes⁶⁹, ⁷⁰, ⁷¹.

The Capitalization Rate (Cap Rate) is then used to estimate the potential rate of return an investor might expect from the property. It is calculated by dividing the NOI by the property's current Market Value or purchase price⁶⁷, ⁶⁸.

The formula for valuing a multi family property using the Cap Rate is:

\text{Property Value} = \frac{\text{Net Operating Income (NOI)}}{\text{Capitalization Rate (Cap Rate)}}

Conversely, the Cap Rate can be calculated as:
