HMO Mortgages | What Lenders Check Beyond Standard Buy to Let

Last Updated: August 2026

Featured in The Telegraph • Daily Mail • The Times • Sky News

An HMO, a house in multiple occupation, is let room by room to tenants who are not one household. The rent is usually higher than a single let, and so is everything around it: licensing, planning, valuation and the questions lenders ask. I arrange HMO mortgages as part of my buy to let work, whole of market, with a flat £350 fee. Here is what actually decides an HMO application.

In England, three or more tenants from more than one household sharing facilities makes a property an HMO. Five or more means a mandatory council licence

Lenders differ on the big three: how many rooms they will take, whether they want landlord experience, and how they value the property

How I place an HMO mortgage

1

Step 1

First Chat

Tell me the property, the number of lettable rooms, the expected rent and whether you are buying personally or through a limited company. If the property already holds a licence, say so.

2

Step 2

Research

I check which lenders fit your case: room count, licensing status, your landlord experience and how each lender will value the property and treat the rent.

3

Step 3

Application

If the numbers work, I handle the application and stay the point of contact through valuation and underwriting, which is where HMO cases usually need the most attention.

4

Step 4

Completion

Your mortgage offer is issued and my flat £350 fee becomes payable. If no offer is issued, you owe me nothing.

About

Our approach.

Most HMO cases turn on two questions: is the property genuinely an HMO in the eyes of the council, and how will the lender value it. In England, a property let to three or more tenants from more than one household who share a toilet, bathroom or kitchen is an HMO, and once five or more tenants share, it needs a mandatory licence from the council (the GOV.UK guidance sets out the definitions). Lenders check this before they lend, not after.

Valuation is the part that surprises people. Some lenders value an HMO as a standard house, whatever the room rents add up to. Others, usually on larger HMOs, use an investment valuation based on the rental income. The same property can support quite different borrowing depending on which basis your lender uses, which is why lender choice matters more here than on a standard buy to let.

How I help

I check the property against the council’s licensing position, match the room count and your experience to lenders who genuinely take that case shape, and make sure the rent figure used is one the valuer is likely to support. HMO criteria vary between lenders more than almost any other corner of buy to let.

Who this is for

Landlords buying or converting a shared house, first time HMO buyers stepping up from a standard buy to let, and limited company or SPV buyers. If you are weighing an HMO against a block of self-contained flats, that is a multi-unit freehold block and I cover it separately.

Frequently Asked Questions

Have another question?

A buy to let mortgage for a property let room by room to unrelated sharers rather than to one household on a single tenancy. Lenders treat HMOs as their own category because the income, the wear and the regulation are all different from a standard single let.

In England, a property let to at least three tenants forming more than one household who share a toilet, bathroom or kitchen. Once at least five tenants share, it is a large HMO and needs a mandatory licence from the local council. Some councils run additional or selective licensing schemes that catch smaller HMOs too, so check with the council for the specific property. Student houses are the classic example, and my student buy to let guide covers that world specifically.

You do not usually need the licence in hand to apply, but lenders want to see that the property holds a licence, has one applied for, or does not need one. Operating a licensable HMO without a licence is an offence, so I check the licensing position at the start rather than letting it surface at underwriting.

Some lenders will consider a first time landlord for a smaller HMO, others want standard buy to let experience first, and criteria change regularly. This is one of the questions I check against the panel for your specific case rather than assuming either way.

Yes, many landlords hold HMOs through a limited company or SPV. The lending works like other company buy to let: expect a personal guarantee, and take the tax question to an accountant before deciding the structure. I arrange SPV mortgages too.

Both vary by lender. Smaller HMOs are often valued as a standard house and stress tested like an ordinary buy to let. Larger HMOs may get an investment valuation based on the room rents, and some lenders apply a deduction for running costs before testing whether the rent covers the mortgage. The valuation basis can change the borrowing materially, so it is worth knowing before you apply.

Plan on 25%, the same working assumption as most buy to let lending. Some lenders want more for larger or more complex HMOs. What you can then borrow is decided by the rent cover test, not just the deposit.

An HMO is one property where tenants share facilities like a kitchen or bathroom. A multi-unit freehold block is one freehold containing several fully self-contained flats, each with its own front door and facilities. Lenders treat the two differently and some only lend on one of them.
