What Is an HMO?
A house in multiple occupation (HMO) is a property rented to three or more tenants who form two or more separate households and share facilities such as a kitchen or bathroom. Common examples include student houses, professional house shares, and bedsit-style accommodation.
HMOs are subject to additional regulations, including mandatory and additional licensing schemes depending on the property size and local council rules. A property occupied by five or more tenants forming two or more households requires a mandatory HMO licence from the local authority.
HMO Mortgage Requirements
Not all buy-to-let lenders offer HMO mortgages. Those that do typically require a larger deposit — often 25% to 30% — and assess affordability based on the combined room-by-room rental income rather than a single tenancy figure.
Lenders will also want to see that you have experience as a landlord, hold the necessary HMO licence, and that the property meets all fire safety and housing standards. First-time landlords may struggle to access HMO mortgages, as most lenders prefer borrowers with a track record of managing rental properties.
Yield Potential
The main attraction of HMOs is higher rental yield. Letting individual rooms generates significantly more income than letting the same property to a single household. For example, a four-bedroom house might achieve £1,200 per month as a standard let but £2,000 or more as an HMO with four rooms let individually.
However, higher income comes with higher costs and more intensive management. Bills are typically included in HMO rents, tenant turnover is higher, and maintenance demands increase with more occupants. Factor in all costs to calculate the true net yield before committing.
Licensing and Compliance
All HMOs housing five or more people from two or more households require a mandatory licence. Many local authorities also operate additional licensing schemes covering smaller HMOs. Operating without a licence is a criminal offence that can result in unlimited fines.
Licence conditions include minimum room sizes, maximum occupancy limits, adequate fire safety measures, proper waste disposal facilities, and suitable kitchen and bathroom provision for the number of occupants. Annual gas safety certificates, electrical safety inspections, and compliance with the Management of Houses in Multiple Occupation Regulations are also required.
Important: Your home may be repossessed if you do not keep up repayments on your mortgage. There will be a fee for mortgage advice. The actual rate available will depend on your circumstances. Think carefully before securing other debts against your home.
