Duplex
Definition and meaning of Duplex in real estate.
A duplex is a single residential building containing two separate living units, each with its own entrance, kitchen, and bathroom facilities.
In more detail
The two units can be arranged side-by-side, sharing a common firewall, or stacked on top of each other with a floor separating them. Duplexes are popular among investors and multi-generational families because they offer a balance of density and privacy. Buyers often practice house hacking, a strategy where they live in one unit and rent out the other to cover their mortgage payments.
The entire property is typically held on a single deed, though some jurisdictions allow units to be subdivided and sold separately.
