## HMO commercial mortgages

Houses in Multiple Occupation (HMOs) represent one of the most common use cases for commercial buy-to-let mortgages, particularly where property size, tenant profile, or income structure falls outside standard buy-to-let criteria.

Unlike mainstream buy-to-let lenders, which typically value HMOs on a bricks-and-mortar basis, commercial buy-to-let lenders can apply income-led valuation methodologies, such as Market Value 1 (MV1). This approach treats the property as an income-producing investment rather than a single residential unit, often supporting higher valuations and increased borrowing capacity.

Commercial buy-to-let lenders also demonstrate broader appetite across complex HMO profiles. This includes large HMOs (typically 7+ bedrooms), student-only accommodation, supported or specialist housing, and properties let to vulnerable tenant groups, scenarios that are frequently restricted or excluded under standard buy-to-let policies. In these cases, commercial facilities may support borrowing of up to circa 75% LTV, subject to income sustainability and risk profile.

Underwriting is driven primarily by cash flow and asset performance, rather than prescriptive landlord experience thresholds or unit caps. As a result, commercial buy-to-let mortgages can be suitable for both experienced operators and newer investors, provided the property and income structure meet lender requirements.
