A ROOMER is a type of tenant who rents a room in a shared living space, such as an apartment or house. Roomers typically pay rent to the landlord or property owner and share common areas with other tenants. Roomers may also be responsible for their own utilities and may have access to amenities such as a kitchen, laundry facilities, and a living room. Roomers are often students or young professionals who are looking for a more affordable living situation than renting an entire apartment or house.
