Duplexes offer numerous benefits, including affordability, low maintenance, and the potential for passive income. Since you share a wall with your neighbor, duplexes can be more affordable than single-family homes. They also require less maintenance than larger homes, as you typically only need to maintain your half of the property.

Moreover, if you purchase a duplex and live in one unit while renting out the other, you can generate passive income. This can help cover your mortgage and other living expenses, making duplexes an attractive option for both homeowners and investors.
