HMO Mortgages

Specialist mortgage finance for Houses in Multiple Occupation

Houses in Multiple Occupation, commonly known as HMOs, can provide landlords with the potential for higher rental income than a standard single-let property.

However, financing an HMO can be more complicated than arranging a conventional buy-to-let mortgage.

Lenders may consider the number of occupants, property layout, licensing requirements, rental income, location, landlord experience and the overall property investment.

At Cambs Ely Mortgages, we help landlords and property investors explore suitable HMO mortgage options, whether you're purchasing your first HMO, converting an existing property or refinancing an established HMO investment.

We work with a wide range of lenders, including specialist providers, to help you find finance based on the individual circumstances of your property and investment strategy.

What Is an HMO?

A House in Multiple Occupation is broadly a property occupied by people who are not all part of the same household and who share facilities such as a kitchen or bathroom.

HMOs can take many different forms.

For example, a property might contain several individual bedrooms that are rented separately to unrelated tenants while they share communal facilities.

The exact legal definition and licensing requirements can depend on the property and local authority rules.

This means it is important to establish the property's HMO status before applying for finance.

How Does an HMO Mortgage Work?

An HMO mortgage is a specialist form of buy-to-let finance designed for properties being operated as HMOs.

The lender may assess both the property and the expected rental income.

This can include:

  • Number of bedrooms

  • Number of tenants

  • Property layout

  • Expected rental income

  • Property value

  • HMO licence

  • Planning/use requirements

  • Location

  • Condition of the property

  • Landlord experience

  • Existing portfolio

  • Borrower's financial position

Not every buy-to-let lender will accept HMOs, and those that do can have very different criteria.

Can I Get a Mortgage for My First HMO?

Potentially, yes.

You don't necessarily need to own an HMO already to apply for HMO finance.

Some lenders are willing to consider landlords purchasing their first HMO, although criteria can vary significantly.

The lender may look closely at your overall experience, financial position and the proposed investment.

For a first HMO, it can also be important to demonstrate that you understand the responsibilities involved in managing the property.

A strong application should clearly explain the property, proposed rental income and how the HMO will be operated.

How Many Tenants Can an HMO Have?

There isn't one single answer because HMO rules can depend on the property and circumstances.

Certain HMOs are subject to mandatory licensing, while additional licensing schemes can apply in some local authority areas.

The number of occupants, households, facilities and property configuration can all be relevant.

Local councils can also have their own licensing requirements.

Before purchasing or converting a property, it's therefore important to check the requirements of the relevant local authority.

Do I Need an HMO Licence?

Potentially.

Licensing requirements depend on the type and size of the HMO and the rules applying in the relevant local authority.

Some HMOs fall under mandatory licensing requirements, while councils can introduce additional licensing schemes.

A property may therefore require a licence even where it doesn't fall into the national mandatory licensing category.

This is important from both a legal and mortgage perspective.

A lender may require evidence of licensing or confirmation that the property will meet the relevant requirements.

How Is HMO Rental Income Assessed?

Rental income is a key part of HMO mortgage applications.

Instead of simply looking at the rent from the entire property as one tenancy, the lender may consider the expected rental income from the individual rooms or units.

For example:

6 rooms × £650 per month = £3,900 potential monthly rent

However, the lender may not simply accept the landlord's estimate.

They may consider:

  • Valuer's rental assessment

  • Local rental market

  • Room sizes

  • Property condition

  • Number of occupants

  • Existing tenancy arrangements

  • HMO licence

  • Location

The lender's own rental calculation and stress-testing requirements will determine how much borrowing may be available.

Can I Convert a Standard Property Into an HMO?

Potentially, but the finance needs to reflect the proposed works and intended use.

If you're purchasing a property that will require significant refurbishment or conversion before becoming an HMO, a standard HMO mortgage may not necessarily be the appropriate starting point.

Depending on the project, bridging finance or refurbishment finance may be considered.

Once the property is completed and meets the relevant requirements, it may then be possible to refinance onto longer-term HMO mortgage finance.

This is where having a clear plan from purchase through to completion can be particularly important.

Can I Buy an HMO Through a Limited Company?

Yes.

Many property investors choose to purchase HMOs through a limited company.

This can be particularly relevant for landlords who are building a larger property portfolio.

However, limited company HMO lending has its own criteria.

Lenders may assess:

  • Company structure

  • Directors

  • Shareholders

  • SIC codes

  • Personal guarantees

  • Landlord experience

  • Rental income

  • Property value

  • Existing portfolio

Some lenders specialise in limited company HMO mortgages, while others may have restrictions.

What Deposit Do I Need?

There isn't a universal deposit requirement for HMO mortgages.

The maximum borrowing available will depend on factors such as:

  • Property value

  • Rental income

  • Number of rooms

  • HMO status

  • Location

  • Borrower experience

  • Company structure

  • Overall lender criteria

A larger deposit can potentially provide access to a wider range of options, but the appropriate level of borrowing needs to be considered alongside the property's expected rental income and investment viability.

What Types of HMO Can Be Financed?

Depending on the lender, HMO finance may potentially be available for different property types, including:

  • Shared houses

  • Professional house shares

  • Student HMOs

  • Worker accommodation

  • Larger HMOs

  • Converted properties

  • Purpose-built HMOs

However, lender criteria can vary considerably.

A property with six bedrooms may be straightforward for one lender but outside another lender's criteria.

What Will an HMO Lender Look At?

HMO lenders can assess a wide range of information.

The Property

The lender may consider the property's location, condition, layout, size and value.

Rental Income

Expected rental income from the rooms can be an important part of the affordability calculation.

Licensing

The lender may want confirmation that the property meets the relevant licensing requirements.

Experience

Some lenders have minimum experience requirements, while others are willing to consider first-time HMO landlords.

Borrower Profile

Your income, credit history, assets, liabilities and wider financial circumstances may all be considered.

Exit Strategy

For purchases involving refurbishment or conversion, the lender may want to understand how the property will be financed and operated once completed.

Important Information

Buy-to-let mortgages are not generally regulated by the Financial Conduct Authority unless specific regulatory conditions apply. The regulatory treatment depends on the circumstances and purpose of the borrowing.

HMO licensing and planning requirements can vary between local authorities. You should obtain appropriate legal and property advice before purchasing or converting a property.

Tax treatment varies depending on individual circumstances and may change in the future. Independent tax advice should be obtained where appropriate.

Your property may be repossessed if you do not keep up repayments on a mortgage or other loan secured against it.

Mortgage availability, rates and lender criteria vary and are subject to underwriting. There is no guarantee that a particular mortgage will be available.

Information correct at the time of writing. Mortgage criteria, licensing requirements, rates and lender availability can change.
