Introduction
Houses in Multiple Occupation (HMOs) are a goldmine for property investors, offering rental yields up to 15% in 2025’s competitive market. However, financing an HMO isn’t as simple as securing a standard buy-to-let mortgage. From stricter licensing rules to complex lender criteria, this guide breaks down everything you need to know to invest confidently in HMOs.
What Is an HMO Mortgage?
An HMO mortgage is a specialist loan for properties rented to 3+ tenants from separate households who share facilities (e.g., kitchen, bathroom).
2025 Licensing Rules:
- Mandatory Licensing: Required for HMOs with 5+ tenants (down from 5+ in 2023).
- Room Sizes: Minimum 6.5m² for single occupants.
- Safety Checks: Annual fire risk assessments and gas safety certificates.
HMO vs. Buy-to-Let Mortgages
| Factor | HMO Mortgage | Standard BTL Mortgage |
| Deposit | 25%–35% | 20%–25% |
| Interest Rates | 5%–7% | 4%–5.5% |
| Rental Coverage | 145%–160% of mortgage interest | 125%–145% |
Pros and Cons of HMO Investments

- Deposit: Minimum 25% (35% for first-time HMO landlords).
