HMO Mortgage UK – Finance Solutions for Multi-Let Properties

What is an HMO?

A property is considered to be a House in Multiple Occupation (HMO) if three or more unrelated persons occupy the property with self-contained rooms and shared communal facilities such as bathrooms and kitchen.

At Commercial Finance Network, we operate nationally throughout the UK and arrange HMO finance for all sizes and types of HMO properties. Some typical examples include:

• A shared house with one or more ASTs
• Houses converted into self-contained bedsits
• Student halls or student house-shares
• Lodging houses
• Houses converted into B&Bs
• Shared flats
• Purpose built blocks with multiple self-contained units

With continued changes to HMO legislation and the ongoing tightening of HMO licensing specifications both nationally and by local authorities, landlords are finding that more and more HMOs now require a licence in which to operate legally.

We work with all the specialist HMO lenders who offer finance to both licensed and unlicensed HMOs, so long as the appropriate local amenity standards are adhered to and the premises are operating lawfully.

Planning, Article 4 and Licensing

Finance and planning sit closer together on HMOs than on any other property type. A lender will not advance against a property operating unlawfully, and planning status changes what the building is permitted to be.

Start with use classes. An ordinary dwelling is C3. A small HMO housing between three and six people is C4. Moving from C3 to C4 is normally permitted development, so no planning application is needed. Push past six occupants and the property becomes sui generis, which always requires full planning permission.

Article 4 directions remove that convenience. Councils apply them to areas where HMO concentration has become a concern, and the effect is to strip out the permitted development right. Inside an Article 4 area, converting a house to a small HMO requires a planning application like any other, and refusal is common. Buy in one of these areas assuming the conversion is automatic and the project stops before it starts. Check the direction before exchange, not after.

Licensing runs alongside planning as a separate requirement. Since October 2018, mandatory licensing applies to any HMO housing five or more people from two or more households, and the old storey threshold no longer features. Many councils operate additional or selective schemes that pull smaller properties in as well, and those rules vary considerably between authorities.

Room sizes carry statutory minimums attached to the licence. A room slept in by one person over ten must reach 6.51 square metres. Two people over ten need 10.22 square metres. A child under ten needs 4.64 square metres. Anything below 4.64 square metres cannot be used for sleeping at all. Surveyors measure. Rooms that fall short get excluded from the income assessment, which drags the valuation down with them.

Lenders check licence status as part of underwriting. Some will accept evidence that an application has been submitted. Others want the licence issued before completion. That distinction decides your timeline, and it is worth confirming early.

These rules apply in England. Wales, Scotland and Northern Ireland operate different regimes, and any HMO finance application needs to reflect the right one from the outset.

Commercial vs Bricks-and-Mortar Valuation in HMO Finance: The Number That Decides the Deal

Two surveyors can walk into the same HMO and produce very different figures. The gap between them is the single biggest factor in what you can borrow, and most landlords meet it only when the valuation report lands.

Bricks and mortar is the first basis. The surveyor ignores the rent roll and asks what the building would fetch as an ordinary house on that street. Comparable sales set the number. A six-bedroom terrace in an area where six-bed houses sell for £250,000 is worth £250,000, regardless of how many tenants pay rent inside it.

Commercial valuation works from income instead. The surveyor takes the annual rent, deducts the cost of running the place, and capitalises what remains at a yield that reflects the location and the quality of the asset. Run those numbers on the same terrace. Six rooms at £550 a month produce £39,600 a year. Operating costs on an HMO with bills included absorb roughly 30%, leaving £27,720. Capitalise that at 9% and the valuation reaches £308,000.

Same building. £58,000 apart.

Now the borrowing. At purchase, lenders advance against the lower of price or valuation, so the commercial figure rarely helps on day one. Buy at £250,000 with 75% lending and the loan is £187,500, with £62,500 down. Hold the property, let the rooms, and refinance twelve months later on a commercial basis, and 75% of £308,000 gives £231,000. That releases £43,500 of capital without selling anything.

Two conditions govern access to this. Size is the first. Many lenders reserve commercial valuation for larger HMOs, often seven bedrooms or more, and assess anything smaller as a house. Location is the second. The capitalisation yield moves with the strength of the local market, and a weaker area attracts a higher yield, which pushes the valuation down rather than up.

Budget on a commercial valuation and receive a bricks and mortar one, and the deal fails at the last moment. Establish which basis a lender will apply before you commit to anything, since it changes what your HMO finance actually needs to achieve.

How Lenders Assess HMO Rental Income

Rent from an HMO arrives room by room, and lenders treat that income differently from a single tenancy. The test itself is the interest coverage ratio, shortened to ICR, and it compares rent against mortgage interest at a stressed rate rather than the rate you pay. Our page on debt servicing ratios in complex HMO deals covers how this differs from DSCR on more complicated cases.

Take the £231,000 refinance above. Stressed at 5.5%, monthly interest reaches £1,059. A 125% test needs rent of £1,323. A 145% test needs £1,535.

The property produces £3,300 a month across six rooms. Cover lands at 312%. Even after a 25% deduction for voids and bills, which many lenders apply as standard, income of £2,475 gives 234% cover. Both figures sail past either bar.

This is why the rent test rarely decides an HMO application. The income is simply too strong relative to the debt. Valuation does the work instead, and that returns you to the section above.

One scenario changes the answer completely. Some lenders will not accept room-by-room income on smaller HMOs and assess the property on what it would achieve as a single let. Suppose that same house lets to one family for £1,400 a month. Cover falls to 132%. A basic rate taxpayer clears 125%. A higher rate taxpayer fails 145% and the loan shrinks.

The rent roll did not move. The lender’s method did. Ask which basis applies before an application goes anywhere, because the difference between room-by-room and single-let assessment reshapes the whole deal.

For landlords modelling a single-let scenario alongside an HMO, our buy-to-let mortgage calculator runs the same ICR test on standard rental income.
