HMO Mortgage FAQ Library

Question 1

What are the occupancy rules for an HMO?

David Sampson · Accepted Answer

In England a house is usually an HMO when three or more people who form more than one household share a kitchen, bathroom or toilet. A mandatory licence generally applies at five or more occupiers. Planning use often changes at seven occupiers (sui generis). The mortgage valuer may count fewer bedrooms than the brochure if rooms fail size or amenity tests.

Question 2

What is the largest mortgage you can get?

David Sampson · Accepted Answer

There is no single maximum HMO loan. Specialist lenders publish their own loan-size and LTV caps; several go to high six- or seven-figure loans on large houses. The binding limit is usually the lower of the lender’s maximum loan, the LTV on the valuation, and the stressed rent. Ask for a quote on the actual house rather than a headline maximum.

Question 3

What is the highest interest rate on a mortgage in history?

David Sampson · Accepted Answer

That is a UK Bank Rate / residential-mortgage history question, not an HMO product term. This page does not publish a live large-HMO rate. Ask for a dated illustration on your case.

Question 4

What are the current HMO mortgage rates for Ltd companies?

David Sampson · Accepted Answer

Limited-company HMO rates are not published as one headline figure on this page. A large house in an SPV is priced on LTV, room count, valuation method and the borrower’s experience. Compare a dated illustration after we match a lender.

Question 5

Is it hard to get a HMO mortgage?

David Sampson · Accepted Answer

It is harder than a single-let buy-to-let because the panel is smaller and the licence, planning and fire pack have to be right. A licensed six-bed with experience is routine on the specialist panel. A 12-bed sui generis conversion with no track record is a narrower case.

Question 6

Are HMO mortgages more expensive?

David Sampson · Accepted Answer

Specialist HMO products often price above vanilla single-let buy-to-let because underwriting and valuation cost more. Large and commercially valued houses can sit higher still. There is no unsourced “from X%” on this page; cost is the rate plus fees on the lender that will actually take the room count.

Question 7

Can I get a mortgage on a 6 bed HMO?

David Sampson · Accepted Answer

Yes. A 6 bed HMO mortgage is a standard specialist-HMO case when the house is licensed (or will be), the planning use is lawful, and the rooms meet size standards. Some lenders publish a six-bedroom cap; others go higher. It is not automatically a commercial loan.

Question 8

How many bedrooms can an HMO mortgage cover?

David Sampson · Accepted Answer

It depends on the lender. Aldermore publishes up to 6 bedrooms. Shawbrook’s SB1 guide caps HMO/MUFB at 10 units. Paragon publishes up to 20 rooms. Kent Reliance’s last guide also went to 20 bedrooms but closed new term buy-to-let in December 2025. Confirm the current cap on the lender’s own page.

Question 9

Does a 7 bed HMO need planning permission?

David Sampson · Accepted Answer

Usually yes for the use. Seven or more occupiers is typically sui generis, so a change from C3 or C4 needs planning permission. A six-occupier C4 house in an Article 4 area also needs permission. A licence is not a substitute.

Question 10

How are large HMOs valued?

David Sampson · Accepted Answer

Small licensed houses are often bricks-and-mortar with a rent cross-check. Seven-plus bedroom or sui generis houses are more often valued on income. The valuer strips out rooms that fail size, licence or fire tests. That figure, not the asking price, is what the lender lends against.

Question 11

Do I need experience for a large HMO mortgage?

David Sampson · Accepted Answer

It helps. Many specialists want around 12 months of landlord or HMO experience. A few take first-time landlords with a professional agent, usually on six rooms or fewer. A first 10+ bedroom conversion without a manager is a much smaller panel.
