HMOs and Multi-Unit Freehold Blocks: What Landlords Need to Know About Sharia-Compliant Buy-to-Let

When a landlord first tells me they want to move beyond a standard single-let property, the conversation usually starts with ambition, and quickly moves to uncertainty.

They may have spotted the potential of an HMO, or found a Multi-Unit Freehold Block (MUFB) that could diversify their rental income. But if they are also looking for halal home finance, the question becomes more specific:

“Can I grow a property portfolio without compromising my faith?”

For many Muslim landlords, conventional interest-based borrowing is not acceptable because of the prohibition of riba. That can create the frustrating feeling of being left behind while other investors expand their portfolios.

The good news is that specialist Sharia-compliant buy-to-let options are developing. StrideUp’s Buy-to-Let Purchase Plan now includes eligible HMOs with up to 12 bedrooms and MUFBs with up to 10 units, subject to status, lender criteria and availability.

This guide explains what that means in practice, and what landlords still need to consider before proceeding.

Important: Product details, fees, property limits and eligibility criteria can change. The information below is educational and is not a promise of approval, rates, returns or finance.

What is an HMO?

An HMO, or House in Multiple Occupation, is a property occupied by people who are not from one household but share facilities such as a kitchen or bathroom.

Examples can include:

• A house let by individual bedrooms to working professionals
• A student property with shared communal areas
• A property occupied by several unrelated tenants
• A larger shared house with separate tenancy agreements

HMOs can offer a different rental-income profile from a standard single-let property. However, they are also more operationally demanding.

Landlords may need to consider:

• Local authority licensing requirements
• Fire safety and room-size standards
• Gas, electrical and energy performance obligations
• More frequent tenant communication
• Higher maintenance and management requirements
• Void periods between individual room lets

A property’s HMO status is not determined only by its number of bedrooms. Local rules, the layout, occupancy and licensing position all matter.

What is a Multi-Unit Freehold Block?

A Multi-Unit Freehold Block, often shortened to MUFB, is a building containing several self-contained residential units held under one freehold title.

For example, one freehold building might contain:

• Four self-contained flats
• Several maisonettes with separate entrances
• A converted house divided into individual apartments
• A small block of residential units owned by one landlord

The key difference between an MUFB and a conventional single-let property is that the building may generate rental income from multiple independent units, while ownership remains connected to a single freehold title.

This can make the property more complex to value, insure, manage and finance.

Why have lenders historically restricted HMOs and MUFBs?

Traditional mortgage lending is often designed around a relatively simple security: one property, one household and one tenancy arrangement.

HMOs and MUFBs introduce additional variables, including:

• Multiple tenants or tenancy agreements
• Different licensing requirements
• Higher wear and tear
• More complicated valuation assumptions
• Potential reliance on specialist rental income
• Greater management responsibilities
• Questions around planning permission and building regulation compliance

From a lender’s perspective, the issue is not necessarily that the property is unsuitable. It is that the risks need to be assessed differently.

A valuer may need to consider both the property’s value as a whole and the income generated by its individual rooms or units. The lender may also examine whether the property could be sold or managed effectively if the landlord experienced financial difficulty.

That is why many mainstream buy-to-let products have restricted the number of bedrooms, units or tenants they will consider.

What has changed for Sharia-compliant buy-to-let?

The current StrideUp Buy-to-Let Purchase Plan has expanded its property criteria to include:

• HMOs with up to 12 bedrooms
• MUFBs with up to 10 units
• A halal, interest-free structure designed to avoid riba
• No minimum income requirement stated in the product information supplied to SM Finance
• No upfront application fee stated in the current product summary
• Potential suitability for experienced portfolio landlords and first-time investment property buyers

These criteria may make specialist halal property finance more relevant to landlords who previously found that their preferred property type fell outside available options.

However, the expanded criteria do not mean every HMO or MUFB will qualify. The property, applicant, rental income, deposit, credit profile and legal documentation will still be assessed.

“No minimum income” should also not be interpreted as “no affordability assessment”. A lender still needs to understand how the plan will be supported, particularly if rental income is lower than expected or the property experiences a void period.

How does a Sharia-compliant Purchase Plan differ from a conventional mortgage?

A conventional buy-to-let mortgage is generally structured as a loan. The lender advances funds, and the borrower repays the capital together with interest and other charges.

A Sharia-compliant Purchase Plan uses a different structure. StrideUp describes its Buy-to-Let Purchase Plan as being based on equity rather than interest.

In broad terms:

1. The landlord contributes a deposit.
2. The finance provider acquires a share of the property.
3. The landlord pays rent for use of the provider’s share.
4. The landlord gradually acquires additional shares over time.
5. As ownership changes, the landlord’s equity increases.

This is commonly explained through concepts such as Diminishing Musharakah, meaning diminishing partnership, alongside a leasing arrangement known as Ijarah.

The important distinction is that the payment is not described as interest on a conventional loan. It is linked to the use of the finance provider’s ownership share under the agreed structure.

StrideUp states that its plan is certified as Sharia-compliant by qualified scholars from Amanah Advisors. Anyone considering halal home finance should still review the product documentation carefully and seek independent religious guidance if they have specific questions about Sharia interpretation.

StrideUp’s own buy-to-let page also states that its buy-to-let products are not regulated by the Financial Conduct Authority. You can read the provider’s current information on its Buy-to-Let Purchase Plan page.

What does the expanded HMO and MUFB criteria not guarantee?

The expanded limits are useful, but they are not an automatic route to approval.

A lender may still assess:

1. Affordability

The lender will need to understand how the proposed payments are supported. This may include:

• Expected rent from the rooms or units
• Personal income, where relevant
• Existing property commitments
• Other household or business expenditure
• Existing portfolio performance
• Cash reserves and deposit size

2. Rental cover

The expected rent may be tested against the proposed payments. This is commonly referred to as rental cover or rental affordability.

The assessment may take account of:

• Current rent
• Market rent confirmed by a valuer
• Allowances for voids and management costs
• The property’s location and tenant demand
• Whether the income is dependent on a particular letting model

A high gross rent does not automatically mean a high net return. Repairs, insurance, licensing, utilities, management and tax can all affect cash flow.

3. Landlord experience

A first-time investment property buyer may be considered for some buy-to-let products, but experience can remain important for specialist cases.

For an HMO or MUFB, a lender may want to understand:

• Whether you have managed tenants previously
• Who will manage the property
• Whether you have appropriate systems and documentation
• Your experience with licensing and compliance
• Whether you have a realistic maintenance budget

4. The property itself

The lender and valuer may review:

• Title structure
• Planning and building regulation history
• HMO licensing
• Number and size of bedrooms
• Number of self-contained units
• Tenancy arrangements
• Condition and construction
• Location and resale prospects
• Freehold and leasehold documentation, where applicable

5. Credit and documentation

You may be asked for evidence such as:

• Identification and proof of address
• Bank statements
• Tax returns or accounts, if self-employed
• Tenancy agreements
• Existing mortgage or finance statements
• A schedule of properties
• Planning and licensing documents
• Details of the property’s management arrangements

Who might this type of finance suit?

A Sharia-compliant HMO or MUFB Purchase Plan may be worth exploring if you are:

• An experienced landlord expanding a property portfolio
• A first-time investor considering a rental property
• Looking for halal home finance that avoids riba
• Interested in a property with multiple rooms or units
• Comfortable with the responsibilities of specialist property management
• Able to provide the required deposit and documentation
• Prepared to assess the investment on a long-term basis rather than relying on short-term returns

It may be less suitable if you have not budgeted for repairs, licensing, management or periods without full occupancy.

Property investment carries risk. Rent can fall, costs can rise and property values can go down as well as up. You remain responsible for meeting the agreed payments even if some rooms or units are vacant.

Practical next steps for landlords

Before making an offer on an HMO or MUFB, consider taking the following steps:

1. Confirm the property classification. Establish whether it is an HMO, MUFB or another specialist property type.
2. Check local authority requirements. Confirm licensing, planning and safety obligations.
3. Prepare a realistic rental schedule. Use achievable rents and include voids, management and maintenance costs.
4. Review the title and plans. Check the freehold structure, unit layout and legal documentation.
5. Organise your financial records. Prepare evidence of income, assets, liabilities and existing properties.
6. Understand the Purchase Plan. Review how ownership, rent, acquisition of shares and exit arrangements work.
7. Compare suitable options. Criteria can differ significantly between providers.
8. Obtain specialist guidance before committing. A broker can help identify whether the property is likely to fit current lender criteria.

Summary

HMOs and Multi-Unit Freehold Blocks can offer landlords a way to diversify beyond a standard single-let property, but they also involve additional licensing, management, valuation and affordability considerations. Sharia-compliant Buy-to-Let Purchase Plans provide an alternative structure to conventional interest-based borrowing, using co-ownership and rental payments rather than riba. Current product information supplied to SM Finance highlights eligibility for HMOs of up to 12 bedrooms and MUFBs of up to 10 units, with no minimum income requirement and no upfront application fee stated. However, every application remains subject to lender criteria, affordability, rental cover, property details, documentation and availability. Product terms can change, so landlords should obtain current information before making financial commitments.
