HMO Property Due Diligence: An HMO property cannot be assessed by rental income alone.

The number of occupants, property layout, licence position and management model may all affect lender appetite. Local planning controls can also determine whether the proposed use is permitted.

For mortgage advisers, early due diligence helps establish whether the property, borrower and proposed finance are likely to fit together.

At a Glance

An HMO is generally occupied by at least three people from more than one household who share facilities.

Before approaching a lender, advisers should check:

• How the property will be occupied.
• Whether an HMO licence is required.
• Whether the existing or proposed use has planning approval.
• The number and size of lettable rooms.
• The expected rental structure.
• The landlord’s experience and management plan.
• Whether the valuation and mortgage application describe the same use.

A strong projected rent does not correct a licensing, planning or property suitability problem.

What Is an HMO Property?

A house in multiple occupation is generally a property rented to at least three people who form more than one household. They usually share facilities such as a kitchen, bathroom or toilet.

The definition is based on occupation and household structure. It is not determined only by the number of bedrooms.

Examples can include:

• A house shared by unrelated professionals.
• Student accommodation with shared facilities.
• A converted house containing several lettable rooms.
• A property occupied under individual room agreements.
• A larger shared property managed by a specialist operator.

The proposed occupation should be established before mortgage criteria are considered.

When Does an HMO Need a Licence?

In England and Wales, a property will normally require mandatory HMO licensing when:

• Five or more people occupy the property.
• They form more than one household.
• Some or all facilities are shared.
• At least one occupant pays rent.

However, councils can operate additional licensing schemes covering smaller HMOs.

Advisers should therefore avoid assuming that a three-person or four-person HMO is outside licensing requirements. The landlord should check the property address with the relevant council.

The landlord can use the official HMO licence checker to locate the appropriate local authority.

A licence may also contain property-specific conditions. These can influence occupancy, improvement costs and the number of rooms that can lawfully be let.

Why Planning and Licensing Are Different

Planning permission and HMO licensing are separate considerations.

A licence concerns the operation, management and safety of the property. Planning concerns whether the building can lawfully be used for its intended purpose.

In some areas, an Article 4 direction removes permitted development rights for certain HMO conversions. A change from a family home to a small HMO may then require planning permission.

An adviser does not provide planning or legal advice. However, identifying an unresolved planning question early can prevent an unsuitable mortgage application.

What Advisers Should Check Before Sourcing an HMO Mortgage

1. Proposed occupation

Confirm:

• The expected number of tenants.
• How many households will occupy the property.
• Whether facilities will be shared.
• Whether rooms will have separate agreements.
• Whether the property is already operating as an HMO.

Lender criteria may differ according to tenant numbers, tenancy structure and property use.

2. Licence position

Establish whether:

• A licence is already in place.
• An application has been submitted.
• The council requires additional licensing.
• The proposed occupancy matches the licence.
• Any licence conditions could affect the mortgage.

A lender may accept an application in progress, while another may require the completed licence before an offer or completion.

3. Property layout

Review the available information on:

• Bedroom sizes.
• Shared kitchens and bathrooms.
• Fire doors and escape routes.
• Communal space.
• Property access.
• Any structural alterations.

The valuer may comment on suitability, condition, demand and future saleability.

4. Rental assessment

HMO rental income may be assessed using:

• Total room rents.
• A market rent provided by the valuer.
• An assumed single-tenancy rent.
• A lender-specific calculation.
• Existing tenancy evidence.

Advisers should not assume that every lender will use the total rent shown on a landlord’s schedule.

Our HMO mortgage guide explains how lenders may consider rental stress testing, documents and landlord experience.

5. Borrower experience

Some lenders consider first-time HMO landlords. Others require previous buy-to-let or HMO ownership.

Relevant evidence may include:

• An existing property portfolio.
• Previous HMO management.
• Use of an experienced managing agent.
• A realistic refurbishment plan.
• Evidence of available contingency funds.
• Understanding of licensing duties.

More complex applications may also fall within the wider area of complex buy-to-let mortgages.

Common HMO Application Problems

Cases can be delayed where:

• The application states fewer tenants than the proposed use.
• The valuation instructions describe a standard buy-to-let.
• The licence permits fewer occupants than expected.
• Planning consent has not been checked.
• Room rents cannot be supported by local evidence.
• The property contains unapproved alterations.
• The borrower’s experience does not meet lender policy.
• Company documents or portfolio schedules are incomplete.

Good packaging does not make an unsuitable case acceptable. It does make the facts clear enough for the lender to assess the case correctly.

Why HMO Advice Requires More Than a Product Search

An HMO mortgage should reflect the lawful and practical use of the property.

The cheapest initial rate may offer little value if the lender does not accept the tenancy model, licence position or landlord profile.

This is the practical principle behind HMO due diligence: finance should follow the property facts, rather than forcing those facts into unsuitable criteria.

HMO Property Due Diligence Checklist

Before sourcing finance, confirm:

• Property address and current use.
• Proposed number of occupants.
• Number of separate households.
• Tenancy arrangement.
• Licence requirement and status.
• Planning position.
• Article 4 restrictions.
• Bedroom and communal space details.
• Existing and proposed rent.
• Valuation basis.
• Landlord experience.

For cases involving short-term funding before an HMO refinance, advisers should also consider whether specialist lending support may be required.

FAQ: HMO Property Due Diligence

Is every shared house an HMO?

Not necessarily. The household relationships, number of occupants and shared facilities determine whether the property meets the HMO definition.

Do all HMOs need a licence?

No. Mandatory licensing normally applies to larger HMOs. However, councils can introduce additional licensing for smaller properties.

Can a first-time landlord obtain an HMO mortgage?

Some lenders may consider first-time landlords. Others require previous buy-to-let or HMO experience. Property size and management arrangements can affect the decision.

Do lenders use the total rent from every HMO room?

Not always. Some lenders use room rents, while others rely on the valuer’s assessment or a lower single-tenancy figure.

Can an HMO be bought through a limited company?

Potentially. The lender may review the company structure, directors, guarantees, deposit source and property investment activity.

Is HMO lending regulated by the FCA?

Many business buy-to-let mortgages are not regulated by the FCA. Regulation depends on the property use and borrower’s circumstances.
