Of the 26 lender brands on our buy-to-let mortgages panel that will consider an HMO, 7 still will once the property is in Northern Ireland. The other 19 will not, on the criteria they published when we pulled the panel in September 2026. That gap is the reason this page exists: the two conditions are usually asked about separately, and it is the combination that decides where a case can go.

Across the 16 matching products, published rates run from 3.5% to 11.8% per year, and the median sits at about 7.1%. A spread that wide on one combination is normal, because the lenders at the sharp end are pricing a narrow slice of cases and the ones at the top are pricing the cases nobody else will take. Neither end is the rate you would be quoted; that comes from the lender after it has seen the file.

The lenders that accept it

Named because panel composition is a fact rather than a recommendation. Inclusion is not an endorsement, the list is not the whole market, and every one of them applies its own checks before it offers anything.

Funding 365, Keystone Mortgages, Mercantile Trust, Moda Mortgages, Paragon Bank, Quantum Mortgages, Shawbrook Bank.

16 live products across 7 lender brands, checked September 2026. Panel composition changes over time.

What to have ready

Because the property is in Northern Ireland, the lenders above will want that evidenced at the start rather than discovered at valuation. Sending a case to a lender that does not accept the combination costs a search on the file and a fortnight, which is the expensive part of getting this wrong. We arrange the case to the lenders whose published criteria it actually fits, and we tell you which ones those are before anything is submitted.

Frequently asked questions

7 distinct lender brands on our buy-to-let mortgages panel have at least one live product that accepts an HMO where the property is in Northern Ireland, out of 26 that accept an HMO at all. Panel figures were checked in September 2026 and composition changes over time.
Across the 16 matching products the published rates run from 3.5% to 11.8% per year, with a median of about 7.1%. Those are product rates on the panel, not an offer to you, and the rate you are given depends on the lender's own assessment.
The matching products span £10,000 to £4m. That is the range of product limits rather than what any one business would be offered, and the amount available to you depends on the security, the income and the lender's checks.
Adding Northern Ireland takes the panel from 26 lenders to 7, so 19 lenders that would otherwise consider an HMO will not on this basis. That is the practical value of knowing both conditions before anything is submitted, because an application to a lender whose criteria you do not meet is a wasted search on your file.
No. It is the lenders on our own panel with a live product matching both conditions when we last pulled the data in September 2026. Other lenders exist that we do not have access to, and panel composition changes month to month, which is why the figure is dated rather than presented as fixed.
