HMO lettings (House in Multiple Occupation) is the process of renting a property to multiple unrelated tenants who share facilities such as kitchens or bathrooms, typically on individual tenancy agreements. It involves enhanced regulatory compliance, including mandatory HMO licensing, stricter fire safety measures, minimum room size requirements, and more intensive management. Operationally, it includes tenant-by-room sourcing, individual rent collection, higher turnover management, and increased maintenance coordination—resulting in higher rental yields but requiring tighter control, compliance, and day-to-day oversight.
