HMO mortgage rates in 2026 start at around 4.5% for a five-year fixed at 75% loan to value on a small licensed HMO, rising to between 5% and 6.5% for large sui generis properties and for HMOs that need a commercial valuation. Deposits run at 20 to 25%, rental income is stress tested at 125 to 145% interest cover depending on how you hold the property, and the lender pool is almost entirely specialist. The high street barely features. This guide covers the rates, the lenders who are actually writing HMO business this year, the stress tests, the valuation question, and the planning and licensing points that decide whether a deal completes.
We arrange HMO mortgages from £250,000 upwards, from four-bed student lets to fifteen-bed sui generis properties on commercial valuations. Clean cases complete in five to seven weeks. The ones that drag almost always drag on licensing or valuation, and both are avoidable with the right preparation.
The numbers first
What are HMO mortgage rates in 2026?
Rates in mid 2026 sit meaningfully above vanilla buy-to-let because the lender pool is smaller and the underwriting is heavier. A standard buy-to-let five-year fix at 75% loan to value prices from the low 4s. The HMO equivalent starts around half a point higher and climbs with property size, planning class and valuation method. The table below reflects what we are seeing on the desks in July 2026.
| HMO type | Typical 5-year fixed | Max LTV | Notes |
|---|---|---|---|
| Small HMO, up to 6 beds (C4 planning) | 4.5% to 5.5% | 80% | Widest lender choice, standard valuation in most cases |
| Large HMO, 7+ beds (sui generis) | 5.0% to 6.0% | 75% | Specialist lenders only, commercial valuation likely |
| HMO on a commercial valuation | 5.25% to 6.5% | 70-75% | Priced on yield, larger loans possible against the same bricks |
| First HMO for a new landlord | 5.0% to 6.0% | 75% | Fewer lenders, most want 12+ months letting experience |
| HMO in a limited company | 4.5% to 5.75% | 80% | Same pricing as personal names at most specialist lenders |
Watch the arrangement fees as closely as the rate. Several specialist lenders now run twin product ranges: a lower rate carrying a 3 to 7% fee added to the loan, and a higher rate with a flat fee. On a £400,000 loan a 5% fee is £20,000 of borrowing you are paying interest on for the life of the product, so the low-rate-high-fee option only wins where the interest cover calculation needs the lower pay rate to make the loan size work. That is a maths exercise we run on every case.

Who is actually lending
Which lenders offer HMO mortgages in the UK?
The active HMO market in 2026 is led by Paragon, Kent Reliance and Precise (both part of OSB Group), Shawbrook, Aldermore, Fleet Mortgages, CHL Mortgages, Landbay, Foundation Home Loans and Hampshire Trust Bank. Between them they cover everything from a four-bed student let to a twenty-bed sui generis property held in a layered company structure.
Two names matter most at the top end. Kent Reliance and Paragon are the lenders with no maximum bedroom count, both lending up to 80% loan to value through limited companies, and both comfortable with manual underwriting where the case needs a human decision rather than a scorecard. Shawbrook and Hampshire Trust Bank do the heavier commercial-valuation work well but generally want landlords with at least twelve months of letting experience, and Shawbrook in particular suits portfolio landlords refinancing several HMOs in one exercise.
The high street is mostly absent. A handful of mainstream lenders will take a small HMO if it looks enough like a family house, but their criteria on room counts, tenancy types and licensing are narrow, and their valuers routinely down-value properties that have been physically adapted for shared living. Most high street lenders simply have no product for what a serious HMO landlord actually owns. Around a third of the HMO enquiries we take are from landlords who went to their own bank first and lost three weeks finding that out.
Knowing which of these lenders wants which property type in any given month is a constant variable, because appetite shifts with each lender’s book. Fleet pulled back on larger HMOs for a period in 2025 and came back in, Landbay sharpened its pricing on six-beds this spring, and the only way to keep on top of it is to be placing this business every week.

The affordability test
How do lenders stress test HMO rental income?
Every HMO mortgage is sized by an interest coverage ratio, or ICR. The lender takes the gross monthly rent, applies a stress interest rate to the proposed loan, and requires the rent to exceed the stressed interest payment by a set margin. Limited companies and basic-rate taxpayers are typically tested at 125% cover. Higher-rate taxpayers borrowing in personal names are tested at 145%, which is a large part of why most HMO purchases now go through companies.
The stress rate depends on the product. Five-year fixed rates are usually stressed at the pay rate itself, sometimes with a small uplift. Two-year products get stressed at the pay rate plus around 2%, with a floor of roughly 5.5%, which slashes the maximum loan. This is why five-year money dominates HMO lending. The rate follows the risk.
HMO-specific wrinkles matter here. Some lenders take the full gross rent across all rooms, others apply a haircut of 10 to 20% to allow for voids and bills-included tenancies, and a few will only count rooms that comply with the national minimum room sizes. Two lenders can look at the same rent schedule and produce maximum loans £80,000 apart, so the lender choice is often the difference between the deal working and the deal dying at decision in principle.
The valuation question
Will your HMO get a commercial valuation or bricks and mortar?
This is the single biggest number in any large HMO deal. A bricks-and-mortar valuation prices the property as a house, by comparison with local sales. A commercial valuation, sometimes called an investment valuation, prices it as an income-producing asset on a yield basis, which on a heavily adapted, fully licensed property in a strong rental area can come out 20 to 40% higher than the house-price figure. We have written a full guide to commercial valuations for HMO property, and our HMO valuation calculator gives you an indicative yield-basis figure in under a minute.
Valuers generally reserve the commercial basis for properties that could not readily revert to family use: seven or more lettable rooms, en-suites throughout, fire doors and panels, sui generis planning, a proper licence. A six-bed C4 with a normal kitchen and no structural adaptation will get a house valuation from almost every valuer in the country, whatever the rent roll says.
Every year we see at least one landlord who has paid an HMO premium for a six-bed on the strength of its income, then discovers at refinance that the lender values it as a standard house and the equity they thought they had built does not exist on paper. Most landlords obsess over the headline rate when the valuation basis is worth far more money to them, because the difference between a bricks-and-mortar figure and an investment valuation on the same seven-bed can run well into six figures.
Planning and licensing
How do Article 4 directions and HMO licensing affect the mortgage?
Licensing first. Any HMO in England housing five or more occupants from two or more households needs a mandatory licence, whatever the size of the building. Councils can also run additional licensing schemes covering smaller HMOs and selective licensing covering whole neighbourhoods, so the five-person threshold is the floor, never the whole story. Lenders will not complete without evidence that the correct licence is held, applied for, or genuinely not required. Licensing is not optional.
When mandatory licensing was extended in October 2018 to cover all HMOs with five or more occupiers regardless of storeys, the government estimated the change would bring an additional 177,000 HMOs into the licensing regime in England, according to the House of Commons Library. Source: House of Commons Library, Houses in multiple occupation (HMOs) England and Wales.
Planning sits alongside licensing and is a separate regime, which trips people up constantly. Three to six unrelated sharers is use class C4, and in most of the country a family house can convert to C4 under permitted development. An Article 4 direction removes that permitted development right, so in Article 4 areas, which now cover large parts of most university cities, converting a house to an HMO needs a full planning application. Seven or more occupants takes the property into sui generis use, which always needs planning permission. Lenders and their valuers check all of this, because an HMO trading without the right planning status has a resale problem and therefore a security problem.
Last year we looked at a seven-bed in Gloucester where the licence was still in the seller’s name, the loft room had been converted without building control sign-off, and the council had an Article 4 direction that the selling agent had never mentioned. The deal completed, but it took a specialist lender, an indemnity policy, a fresh licence application lodged before exchange and eleven weeks of work. Licensing problems kill more HMO applications than credit problems do.
Before you exchange on any HMO, get written confirmation from the council of the property’s planning position and licence status, and hand both documents to your broker on day one. Do this before the valuation is instructed, not after the valuer has flagged it. It costs nothing and it removes the two most common reasons an HMO purchase falls over.
Ownership structure
Should you buy an HMO in a limited company or your own name?
Most HMO purchases we arrange now complete through limited companies, and the tax treatment of mortgage interest is the main driver. Since Section 24 fully took effect, individual landlords paying higher-rate tax cannot deduct mortgage interest from rental profits in the way a company can, and on a leveraged HMO with a five-figure annual interest bill the difference is material. The lending side has caught up: at the specialist lenders that dominate this market, limited company buy-to-let pricing is now the same as personal-name pricing, so the old rate penalty for incorporating has largely gone.
Company borrowing does bring personal guarantees, slightly higher legal costs, and directors’ background checks, and moving an existing personally held HMO into a company is a sale for tax purposes with stamp duty and possible capital gains consequences. Speak to your accountant before you restructure anything. For landlords running four or more properties, lenders also apply portfolio underwriting to the whole book, which we cover on our buy-to-let portfolio mortgage page: expect to submit a full property schedule, and expect the lender to stress the entire portfolio, not just the new purchase.
The big ones
How do large HMO mortgages work for 7+ bed properties?
Large HMOs are a different lending exercise from small ones, and this is where a specialist broker earns their keep. Once a property passes six lettable rooms it is sui generis for planning, it is odds-on for a commercial valuation, and the realistic lender shortlist drops from ten names to three or four. Kent Reliance and Paragon carry no bedroom cap and will fund double-digit room counts at up to 75 to 80% loan to value through a company, Shawbrook and Hampshire Trust Bank will underwrite the bigger and more complex assets on investment valuations, and beyond roughly £1.5m of debt the conversation starts to include commercial term lenders who price off the yield rather than a product sheet.
Underwriting goes deeper too. Expect the lender to want the licence, the fire risk assessment, floor plans showing room sizes against the national minimums, a tenancy schedule, and evidence you have run HMOs before, because most large-HMO lenders will not make a fifteen-bed anyone’s first property. Management agreements matter as well: some lenders are comfortable with rent-to-rent or corporate lets on large HMOs and some will decline the case on that point alone.
What we have seen over the last two years is valuers taking a noticeably harder line on which properties earn the commercial basis, so the packaging has to make the investment case for them: licence, planning history, room schedule, gross and net income, comparable yields. Once I understand the shape of a large HMO case my role is to put that file in front of the right valuer through the right lender, and the difference in outcome between a well-packaged case and a bare application is often the whole deal.
Six-bed licensed HMO in Bristol, £360,000 loan
Purchase price £480,000, all six rooms let at £650 per month for a gross rent of £3,900. The client borrows £360,000 at 75% loan to value in a limited company on a five-year fixed at 5.29%, stressed at the pay rate with 125% cover. Stressed monthly interest is £1,587, requiring rent of £1,984, so the rent covers the test almost twice over and the loan is capped by the valuation rather than the income. On the rent alone this property could support a loan of around £700,000, which is exactly the headroom that makes a later capital raise against it straightforward.
Common questions
Frequently asked questions
What deposit do I need for an HMO mortgage?
Typically 20 to 25% of the purchase price. A small licensed HMO with a strong rent can reach 80% loan to value with lenders such as Kent Reliance and Paragon, while large sui generis properties and those on commercial valuations generally cap at 75%. First-time HMO landlords should budget for 25% because the lender pool at 80% thins out considerably without letting experience.
Can a first-time landlord get an HMO mortgage?
Yes, but the choice is narrow. Most HMO lenders want at least twelve months of buy-to-let letting experience, and a few want ownership of a standard rental property first. A handful will take a first-time landlord on a smaller HMO with a bigger deposit and evidence of a professional managing agent. A fifteen-bed sui generis property will not be anyone’s first purchase with mainstream specialist lenders.
Are HMO mortgage rates higher than standard buy-to-let rates?
Yes, typically by 0.5 to 1.5 percentage points. In 2026 a standard buy-to-let five-year fix at 75% loan to value prices from the low 4s, while comparable HMO products run from around 4.5% for small properties to 6.5% for large HMOs on commercial valuations. The gap reflects a smaller lender pool, heavier underwriting and a more specialist asset.
Do I need an HMO licence before I can get the mortgage?
Lenders need evidence that licensing is in hand before completion. On a purchase, that usually means the licence application is submitted to the council, since a licence cannot transfer from the seller. Any HMO in England with five or more occupants from two or more households needs a mandatory licence, and many councils run additional or selective schemes that catch smaller properties too. Check the specific council’s requirements early.
What is the difference between a C4 HMO and a sui generis HMO?
Use class C4 covers small HMOs of three to six unrelated occupants. Seven or more occupants makes the property sui generis, a class of its own, which always requires planning permission. C4 conversion from a family house is permitted development in most areas, but an Article 4 direction removes that right, so in Article 4 areas even a small HMO conversion needs a planning application.
When does an HMO qualify for a commercial valuation?
Broadly when the property could not easily revert to a family home: seven or more lettable rooms, extensive adaptation such as en-suites and fire compliance works, sui generis planning and a full licence. Valuers price these on rental yield rather than comparable house sales, which can produce a figure 20 to 40% above bricks and mortar. Smaller C4 properties almost always get a standard house valuation.
Is it better to hold an HMO in a limited company?
For most higher-rate taxpayers, yes, because a company deducts the full mortgage interest before tax where an individual landlord cannot. Specialist HMO lenders price limited company and personal borrowing the same, so the historic rate penalty has gone. Take accountancy advice before deciding, because moving an existing property into a company triggers stamp duty and potentially capital gains tax.
How is rental income assessed on an HMO mortgage?
Through an interest coverage ratio. Lenders stress the loan at a notional interest rate and require gross rent to cover the stressed payment by 125% for limited companies and basic-rate taxpayers, or 145% for higher-rate individuals. Five-year fixed products are usually stressed at the pay rate, which is why they dominate. Some lenders apply a 10 to 20% haircut to gross HMO rent for voids and bills.
