How to Build a Profitable HMO Portfolio

What Is an HMO (House in Multiple Occupation)?

An HMO is a rental property where three or more unrelated people share facilities like kitchens or bathrooms. These setups are common in urban areas where affordability and flexible living options are in high demand.

With over 475,000 registered HMOs across the UK and a market value exceeding £75 billion, HMOs are a major part of the UK rental landscape.

Why invest in HMOs: Yields, demand & reduced voids

HMOs offer some of the highest rental yields in the UK – often between 8% and 15%. This is significantly higher than traditional buy-to-let returns. Because each room is let individually, total rental income per property is maximised.

They also naturally reduce risk: if one tenant moves out, you still receive income from the remaining tenants.

HMO market size & growth trends in the UK

The HMO sector continues to grow, driven by:

• Rising demand for affordable, shared housing
• Increasing urbanisation and job clustering in cities
• Professional operators entering the market with higher standards

In 2025, the average HMO yield across the UK is over 10%, with the most lucrative regions seeing yields above 12%.

Best UK regions for HMO investment

Regions offering the best returns for HMOs include:

• North East – Highest average yields
• Yorkshire and North West – Consistently strong demand and rental growth
• Midlands – Balanced affordability and tenant demand
• University cities – Ideal for student HMO strategies

The right location will depend on your target demographic – whether young professionals, students, or low-income renters.

The demographics of HMOs

Your target tenant demographic should guide your location choice. For young professionals, look for areas with:

• Strong employment markets, particularly in sectors attracting graduates
• Good transport links to major business districts
• Vibrant social scenes and amenities
• Affordable living costs relative to local salaries

If targeting students, focus on:

• Proximity to universities and colleges
• Student-friendly amenities and entertainment
• Safe, well-lit neighbourhoods
• Good public transport connections

Our platform lets you filter sites by demographics in addition to planning constraints, helping you find properties that align with your target tenants.

What to look for in an HMO property

When sourcing or converting property for HMO use, look for:

• Minimum room sizes (6.52m² for single, 10.23m² for double)
• Room layouts that support communal living
• Space for multiple bathrooms and a large shared kitchen
• Fire safety features and escape routes
• Adequate soundproofing between rooms

Searchland’s platform helps you filter opportunities by these characteristics.

Licensing & legal requirements for HMOs

Most HMOs require mandatory licensing, particularly if:

• The property houses 5 or more tenants from more than one household
• The building has multiple storeys (in many local areas)

Some councils also enforce additional licensing rules. These can include stricter space standards, limits on the number of HMOs in a given area, and specific fire safety regulations.

Before purchasing, always check:

• Local council licensing rules
• Article 4 directions limiting permitted development
• Compliance with national housing standards

Managing an HMO: Costs and considerations

HMOs are high-yield, but they require proactive management. Key considerations:

Tenant Management:

• Individual agreements
• Rent collection per room
• Conflict resolution and rules for shared spaces

Property Maintenance:

• Weekly cleaning and regular safety checks
• Planned upgrades and seasonal maintenance
• Utility management and cost-sharing

Financial Planning:

• Budgeting for voids, repairs, and licensing
• Insurance and tax compliance

The future of HMO investment

The HMO sector is professionalising fast. With more competition and higher tenant expectations, future success will rely on:

• Better management practices
• Adapting to regulatory changes
• Embracing data-led decision making

Premium HMOs – those with high spec finishes and better communal living – are increasingly preferred by young professionals and students.
