Key considerations for first-time landlords looking to rent to multiple tenants via an HMO – Lane

However, for first-time landlords, they come with additional complexity, particularly when it comes to finance, regulation, and tenant profiles.

Most lenders offering HMO mortgages will accept first-time landlords for properties housing up to six tenants. These standard small HMOs usually qualify for HMO-specific buy-to-let (BTL) products. However, once a property exceeds six tenants or involves specialist tenant types – such as social housing or supported living – many lenders reclassify the deal, which can push borrowers into commercial mortgage territory.

Commercial mortgages tend to carry higher rates and fees, and the underwriting process is often more rigorous.

The tenant type is a key consideration. While professional tenants or students in smaller HMOs may be straightforward, properties let to vulnerable tenants, asylum seekers, or those on Housing Benefit under long-term lease agreements can limit lender choice.

Some high street lenders exclude these entirely or require the borrower to have significant experience. In such cases, even if the property is residential in structure, the presence of specialist tenants can necessitate commercial mortgage lending.

A growing number of lenders are offering yield-based valuations on HMO mortgages, which allow the rental income – rather than the bricks-and-mortar value – to drive the borrowing potential. This can be advantageous when trying to maximise leverage. In the best cases, these products also come with competitive BTL mortgage interest rates.

However, most lenders offering these terms require at least 12 months of landlord experience. Without that, first-time buyers may find themselves limited to standard bricks-and-mortar valuation methods, which often result in lower loan sizes. Some exceptions exist for borrowers with high earned incomes or strong overall affordability, but these are assessed on a case-by-case basis.

From a compliance standpoint, HMOs are far more regulated than standard BTL properties. Landlords must be aware of mandatory licensing, minimum room sizes, fire safety requirements, and local Article 4 restrictions. Many councils operate additional licensing schemes, particularly in student-heavy or high-density areas, and the cost of compliance can be significant.

Managing an HMO also brings operational challenges. Higher tenant turnover, shared facilities, and ongoing maintenance issues require a more hands-on approach. Many landlords appoint specialist letting agents to manage these properties, which improves compliance but reduces net yields.

For first-time landlords, the HMO model can be an excellent way to achieve higher returns – but it requires careful planning, the right finance, and a solid understanding of regulatory obligations. Entering the market with realistic expectations and a clear long-term strategy is key to avoiding costly mistakes and ensuring sustainable profitability.
