What Is an HMO?

An HMO is a property rented to 3 or more tenants from 2 or more separate households who share facilities such as a kitchen or bathroom. HMOs generate significantly higher yields than single-let properties — typically 10-18% gross — because you rent by the room rather than the whole property.

Licensing

Mandatory Licensing: Required for HMOs with 5 or more people from 2 or more households, regardless of the number of storeys. Costs typically £500-1,500 per licence, valid for up to 5 years.

Additional Licensing: Many councils operate schemes covering smaller HMOs (3-4 people). Check your local authority's website.

Selective Licensing: Some areas require all rented properties to be licensed, not just HMOs.
