HMO Mortgages for Expats
A house in multiple occupation – several unrelated tenants under one roof, each with their own tenancy – can generate rental yields well above a standard single-let, which is exactly why so many landlords eventually end up asking us about one. It’s also why HMO lending is a genuinely specialist part of the mortgage market: valuations work differently, licensing requirements vary by council, and a fair number of lenders simply won’t touch them – fewer still will consider a non-UK resident applicant.
We’ve arranged HMO finance for expat landlords since 2008, from small shared houses through to larger multi-unit blocks, working with clients from our UK, Hong Kong and Kuala Lumpur offices.
What Is an HMO Mortgage?
An HMO mortgage is a specialist buy-to-let mortgage for a property let to three or more unrelated tenants who form more than one household but share facilities such as a kitchen or bathroom. Unlike a standard buy-to-let, which is assessed against a single tenancy and one rent figure, an HMO mortgage is underwritten against the total room-by-room rental income the property can achieve – which is exactly why HMO lending sits with a smaller pool of specialist lenders rather than the mainstream buy-to-let market.
What Counts as an HMO?
A property is generally an HMO where three or more tenants from two or more separate households share amenities. Whether it also needs a licence is a separate question, governed by different, and sometimes overlapping, sets of rules.
Mandatory HMO Licensing
Since October 2018, any property let to five or more people forming two or more households requires a mandatory HMO licence from the local council, regardless of the number of storeys. Below that threshold, a property can often operate as a “small HMO” or multi-let without a licence, typically under planning use class C3 – the same class as an ordinary family home, which matters because it keeps the property easier to sell to a wider pool of buyers, not just investors.
Additional and Selective Licensing
Beyond the mandatory national scheme, many local authorities – particularly in London and other high-demand rental areas – run their own additional or selective licensing schemes covering smaller HMOs the national rules don’t catch. What’s required genuinely varies street by street, so it’s always worth checking the specific local authority’s current position before assuming a property does or doesn’t need a licence.
How HMO Mortgages Are Assessed Differently
Room-by-Room Rental Assessment
Rather than one rent figure, lenders assess total achievable rent across all rooms individually, alongside room sizes and how the property is licensed with the local council. This is also why HMO valuations tend to cost more and take longer than a standard buy-to-let – the surveyor needs to assess room-by-room rental value using local comparable HMO evidence, not just value the property as a single unit.
Rental Cover Ratios
Most HMO lenders require rental cover – the ratio of achievable rent to mortgage interest – of around 125% to 145%, somewhat higher than a typical single-let buy-to-let, reflecting the additional void and management risk lenders attach to multi-let properties.
Deposit and Loan-to-Value Requirements
Deposit requirements for HMOs are generally higher than for a standard buy-to-let:
- 20-25% deposit (75-80% LTV) is the typical starting point for most HMO purchases
- 15% deposit is sometimes achievable for experienced landlords with a strong track record and clean credit
- 30%+ deposit is often required for larger HMOs (seven bedrooms or more) or properties in certain higher-risk locations
As an expat specifically, expect to sit toward the higher end of these ranges in most cases, since non-resident status narrows the lender pool further on top of the HMO-specific requirements.
Personal Name or Limited Company Ownership
Section 24 and Why Structure Matters
Since the Section 24 tax changes, individuals owning buy-to-let property – including HMOs – in their personal name can no longer deduct mortgage interest as a business expense before calculating tax; instead, they receive a 20% tax credit on that interest, which can push higher-rate taxpayers into a considerably less favourable position than under the old rules. This is a major reason most new HMO investors now purchase through a limited company (SPV) structure, where mortgage interest remains a deductible expense against corporation tax. Our UK Limited Company Mortgages page covers that structure in more depth, and this is genuinely a decision worth taking proper tax advice on before purchase, not after.
HMO Yields vs Standard Buy-to-Let
Well-run HMOs typically achieve yields in the region of 8-12%, compared with an average closer to 5-6% for standard single-let buy-to-let property – the core reason HMOs remain popular with landlords despite the additional licensing, management and financing complexity. That higher yield needs to be weighed against genuinely higher running costs – more frequent tenant turnover, more intensive management, and licensing and compliance costs a single-let simply doesn’t carry.
Ownership and Scale
- Small HMOs up to six bedrooms, and larger or more complex properties beyond that
- Licensed and unlicensed HMOs, though licensing status will affect which lenders are interested
- Personal name or limited company/SPV ownership
- Refinancing an existing HMO portfolio, not just new purchases
If you’re converting a property into an HMO or building one from scratch rather than buying a ready-made one, our HMO Design & Build Finance page covers the staged funding process, including current room-size licensing standards, for that instead.
The Application Process and Timeline
Budget 8-12 weeks for a standard HMO purchase or remortgage, allowing for the more detailed room-by-room valuation and, where relevant, confirmation of licensing status – sometimes longer for larger, unlicensed, or first-time HMO purchases. Fixed rate terms are worth thinking about deliberately here: a five-year fix often comes with a more favourable stress test at some lenders, supporting higher borrowing, while a two-year fix can suit landlords planning to add value and refinance sooner.
What Makes This Different as an Expat
Beyond the standard HMO considerations above, being a non-UK resident narrows the lender panel further – not every HMO lender accepts overseas applicants, and those that do often apply the more conservative end of the deposit and rate ranges described above. Currency of income, how you’ll manage the property remotely (a managing agent is often expected by lenders for expat-owned HMOs specifically, given the more intensive day-to-day management HMOs require), and your correspondence address all factor into which lenders are realistically available – exactly the kind of matching we’ve specialised in since 2008.

Frequently Asked Questions
How many bedrooms count as an HMO?
Generally three or more unrelated tenants sharing facilities, from two or more households – mandatory licensing then applies once you reach five or more tenants.
Do I need a licence before I apply for finance?
Not always at application stage, but most lenders will want to see licensing sorted, or a clear plan to obtain one, before completion.
What deposit do I need for an HMO mortgage?
Typically 20-25%, sometimes 15% for experienced landlords with a strong track record, or 30%+ for larger HMOs or higher-risk locations. As an expat, expect to sit toward the higher end.
Can I buy an HMO through a limited company?
Yes – many landlords do, largely due to Section 24’s tax treatment of personally-held property, and we regularly arrange this alongside standard HMO lending.
Will I get a better rate on a licensed HMO?
Often, yes, since licensed properties represent lower regulatory risk to a lender.
How long does an HMO purchase or remortgage take?
Budget 8-12 weeks given the more detailed valuation process, sometimes longer for larger or unlicensed properties.
Do I need a UK managing agent as an expat HMO landlord?
Often expected by lenders specifically for expat-owned HMOs, given the more intensive management multi-let properties require compared with a standard single-let.
