Calculate HMO rental income, yield, and profitability. Compare room-by-room HMO income with single let and find your net return after tax and expenses.
A House in Multiple Occupation (HMO) is a property rented to 3 or more unrelated tenants who share facilities (kitchen, bathroom). HMOs typically generate 30-50% higher gross rental income than single lets of the same property, because landlords charge by the room. A 5-bedroom HMO yielding £130/room/week generates £33,800/year, compared to perhaps £18,000 for the whole property on a single let.
A mandatory HMO licence is required for properties in England and Wales with 5+ tenants forming 2+ households. Some local councils require additional licensing for smaller HMOs (3-4 tenants). Scotland and Wales have similar requirements. Licences typically cost £500-£1,000 and last 5 years. Operating an unlicensed HMO can result in fines up to £30,000 and a Rent Repayment Order forcing landlords to repay up to 12 months' rent.
Allowable HMO expenses include: letting agent fees, maintenance and repairs, insurance, furniture replacement (10% wear and tear was replaced by 'replacement furniture relief'), council tax and utilities if you pay them, mortgage interest (limited to basic rate tax credit for individual landlords), HMO licence fees, accountancy fees, and legal costs. Capital improvements (extending, converting) are not immediately deductible but attract capital allowances.
For higher-rate taxpayers, operating an HMO through a limited company can be significantly more tax-efficient. The company pays corporation tax (19-25%) rather than 40% income tax, and mortgage interest is fully deductible. However, extracting profits incurs dividend tax. The benefit depends on your total income, mortgage costs, and whether you reinvest profits. Many experienced HMO investors use limited companies for portfolio expansion.
Key HMO risks: Higher void periods between tenants (each room at different tenancy stage); more wear and tear from higher occupancy; complex management requirements (tenant disputes, shared areas); need to comply with HMO regulations (fire safety, room sizes, amenities); potential planning permission requirement for larger HMOs (Article 4 Direction in many areas); difficulty in obtaining HMO mortgage financing (specialist lenders required).
