HMO mortgages aren’t just buy-to-let with extra bedrooms. Lenders value the property differently, cap borrowing at 70-75% loan-to-value, and stress-test the rent before they’ll lend. Get the licensing wrong and none of that matters.
If you are looking to buy a shared house and let it out room by room, you will need an HMO mortgage rather than an ordinary buy-to-let.
Lending on a house in multiple occupation, or HMO, is a specialist area with fewer lenders, a different way of working out the loan, and a layer of licensing to understand first. Here is how it works in plain terms.
What makes an HMO mortgage different
A standard buy-to-let mortgage is designed for a property let to a single household.
An HMO is let to several tenants who are not one household and who share a kitchen or bathroom, so the rent builds up room by room. That higher, room-based income is the attraction, and it is also why HMO lending works differently.
Fewer lenders operate in this space, they tend to want a landlord who understands the extra management involved, and they size the loan in a way that reflects the property’s income rather than treating it as an ordinary house.
How much can you borrow?
Two things decide the size of an HMO mortgage: how the property is valued, and how the rent stands up to the lender’s stress test.
Valuation: bricks and mortar, or commercial
A lender will value an HMO in one of two ways.
A bricks-and-mortar valuation treats the property like an ordinary house and compares it with similar homes sold nearby. Most lenders use this for smaller HMOs, so your borrowing is tied to that residential value however strong the rent is.
A commercial, or investment, valuation instead values the property on the income it produces: the surveyor takes the rent, deducts running costs, and applies a yield to reach a figure. For a high-yielding, well-run HMO that can produce a higher value, and support a larger loan. It is most common on larger HMOs of around seven rooms or more.
In short, the more the property behaves like a business, with more rooms, higher rent and professional management, the more likely a lender is to value it on its income and lend against that.
Loan-to-value and deposit
Loan-to-value, or LTV, is the size of the mortgage as a percentage of the property’s value.
HMO lenders typically go up to around 70 to 75 per cent, so plan for a deposit of roughly a quarter to a third of the price. First-time HMO landlords may find the range a little tighter, and the exact ceiling depends on the property, its location and the tenant profile.
The rental stress test
Even when the value supports a large loan, the rent has to cover it comfortably. Lenders check that the expected rent covers the mortgage interest by a set margin, and they do so at a stressed interest rate higher than the actual pay rate, to be sure the property still works if rates rise.
Because that stress rate is applied to the whole loan, two lenders can arrive at very different maximum loans on the same property. The strong room-by-room income of a good HMO is exactly what helps it pass this test.
Do not forget licensing
Before you buy, check the property’s licensing position.
Any HMO with five or more occupants from two or more households needs a mandatory licence across England. On top of that, many councils run additional licensing for smaller three or four-tenant HMOs, or selective licensing covering all rented homes in an area.
It is entirely local, so the council’s own pages are the place to confirm it.
There is also planning: an Article 4 direction can remove the automatic right to convert a home into an HMO, meaning you would need planning permission. Lenders will expect the licensing and planning position to be clear.
Personal name or limited company?
HMOs can be held personally or through a limited company or special purpose vehicle (SPV). Many investors use a company for tax reasons, but the right answer depends on your own circumstances and should be taken alongside advice from a tax adviser or accountant. Lenders offer HMO mortgages under both, so it is worth settling early because it shapes which products are open to you.
Where a broker helps
Because the HMO market is specialist and lenders differ so widely on valuation, LTV and how they stress the rent, matching the property to the right lender is where good advice earns its keep.
