If you want to create dependable passive income through real estate, few methods are as easy and effective as investing in small multi-unit residences. From duplexes to triplexes and fourplexes, multi-unit houses are wise for investors who want to generate monthly cash flow without large amounts of debt or a management role in a large apartment complex. In this guide, I'll show you what is possible in building a rental income stream for small multi-unit homes as we explore strategies that work in 2025 and beyond.
The beauty of small multifamily properties is that they allow novice and experienced investors to extract pretty solid rental income from smaller properties by combining price point, scalability, and tenant operations manageable by an owner-operator.
We'll take you through all the most important things you need to know to acquire, finance, and manage your small multi-units so you can convert rental income into lifelong wealth.
Unlike a gigantic apartment building, small multifamily properties, usually classified as two to four units, are much less expensive to buy and easier to finance.
Example:
A duplex might cost $350,000 compared to $1.2 million for a 10-unit building. However, it provides multiple income streams.
Now, you have two to four tenants paying rent, which increases your income per property. Small units may also provide a stronger rental yield than a single-family rental.
With a small multi-unit, you can better mitigate risk—if one tenant moves out, other tenants pay you rent, instead of just a vacant single-family rental unit or property.
Properties with four units or fewer can be financed as "residential," meaning you can qualify for conventional financing and potentially lower rates and easier terms.
Most investors start with a duplex (learning the ropes!) and then move into larger assets when they feel comfortable with the process and have built up confidence and more capital.
