## Small HMO mortgage

Not all Houses in Multiple Occupation (HMOs) require planning permission or HMO licensing, and where a property falls outside these requirements there are a select number of lenders that may consider a Buy to Let mortgage for HMO use. In the right circumstances, this can result in more attractive interest rates when compared with specialist buy-to-let HMO mortgages or commercial mortgage products for HMOs.

When lending via a limited company (SPV), available options are typically more restricted, although there remain a wide range of small HMO mortgage products across the market. A whole-of-market comparison is essential to identify the most cost-effective HMO mortgage solution, balancing rate, fees, loan-to-value (LTV), and valuation methodology.

Whichever mortgage route proves most cost effective, it must incorporate a suitable HMO valuation method for the property being offered as security, ensuring adequate mortgage funding is achieved. There are usually multiple HMO mortgage options with no experience in property, and for small HMOs, many lenders do not require prior HMO experience, meaning mortgage products remain competitive for first-time HMO investors.

### Valuation Methods for Small HMOs

Small HMOs, particularly those that are dated or conform to basic modern standards, will often be assessed using a bricks-and-mortar valuation. This valuation method focuses on the physical structure, layout, and condition of the property, with limited emphasis on the enhanced income generated from multiple tenancies.

### Why bricks-and-mortar valuations are often suitable for small HMOs

### Simplicity and cost-effectiveness

Bricks-and-mortar valuations are less complex and therefore cheaper than commercial or income-based valuations. They are typically adequate where the property has not been heavily adapted for multiple occupation and remains comparable to a standard residential dwelling.

### Lower interest rates

Mortgages supported by bricks-and-mortar valuations often attract lower interest rates, as the lender’s risk profile aligns more closely with standard residential or vanilla buy-to-let lending, reducing underwriting complexity.

### Wider lender access

More lenders are comfortable with this approach, increasing competition and improving pricing for borrowers.

### Bespoke HMO Mortgage Products and Enhanced Valuations

For boutique small HMOs or properties that have been significantly upgraded, bespoke HMO mortgage products are often more appropriate. These properties may warrant alternative valuation methods such as a hybrid valuation or a Market Value 1 (MV1) commercial valuation.

### Hybrid and MV1 valuations

These valuation approaches consider both the physical asset and its commercial potential, assessing value based on rental income, yield, and sustainability of cash flow. This is particularly relevant for properties featuring high-end finishes, individual en-suite rooms, professional layouts, or enhanced communal facilities, all designed to maximise rental yield.

### Cost versus benefit

While bespoke HMO mortgage products using hybrid or MV1 valuations may come with higher interest rates, they can deliver more accurate and often higher valuations, unlocking greater borrowing capacity. This can be advantageous for investors who have made substantial capital investment or are targeting premium rental markets, where income significantly exceeds standard buy-to-let norms.

### Choosing the Right HMO Mortgage and Valuation Strategy

Selecting the most appropriate HMO mortgage and valuation method depends on several key factors:

### Property type and size

Standard small HMOs with minimal deviation from residential use are often best suited to bricks-and-mortar valuations, while boutique or enhanced HMOs may justify a more detailed commercial approach.

### Investment strategy

Investors prioritising long-term income growth from high-spec or optimised HMOs may accept higher rates in exchange for increased leverage and valuation accuracy.

### Market conditions

Local tenant demand, rental levels, and supply constraints play a critical role. In high-demand areas, HMOs with superior amenities may command premium rents, supporting valuations that go beyond traditional residential comparables.

A structured approach, aligning valuation methodology, lender criteria, and investment objectives, is essential to securing the most effective small HMO mortgage solution and maximising both funding efficiency and long-term returns.
