A fourplex is a type of residential building that contains four separate living units. Each unit typically has its own entrance, kitchen, and bathroom, allowing for independent living. Fourplexes are often found in urban areas and can be an attractive option for both investors and homeowners looking to generate rental income. These buildings are a form of multi-family housing, similar to duplexes and triplexes, but with more units. They can provide affordable housing options and foster a sense of community among residents. Additionally, owning a fourplex can help individuals manage their mortgage costs by renting out the other units.
