HMO Remortgages

HMO remortgages explained

An HMO remortgage replaces your current HMO loan with a new product — either with a new lender or, less often, a new deal with the same one. Landlords remortgage when a fix ends, when they want to raise capital, or when the house can now be valued on income rather than bricks-and-mortar. It is a specialist HMO product, not a standard buy-to-let switch. The new lender will revalue the house, restress the rent, and want a licence that is in date. Compare it with other HMO mortgages if you are also buying, not only refinancing.

There is no single published “HMO remortgage rate” on this page. Price is the new rate plus arrangement, valuation and legal fees, minus any early repayment charge you still owe. Ask for a dated illustration on the house you already own. Limited-company remortgages use the same tests plus company documents; they are not a different headline rate band on this page.

Licensing is part of the remortgage, not an afterthought. The new lender wants the licence that matches the occupancy you are stressing. A house that has quietly gone from five to seven occupiers without a new permission will fail underwriting even if the rent looks strong. Additional and selective schemes still apply on a refinance. Operating after expiry is treated like operating without a licence.

When to remortgage an HMO

The usual trigger is the end of a two- or five-year fix. When that period ends you move onto the lender’s standard variable rate unless you take a new product. Start the process three to six months before the fix ends so you can apply without paying an early repayment charge.

The second trigger is a revaluation. If rents and a lawful occupancy have risen since purchase, a new lender may lend more against the same house. That is how you raise capital for the next HMO. The third trigger is an exit from a bridge or refurbishment loan onto term debt once the licence, fire works and tenancies are in place.

Do not remortgage just because a portal shows a lower headline rate. Model the ERC, fees and the new lender’s stress test. A cheaper-looking rate that fails interest cover on the current rent is not a saving. A house on a 75% LTV purchase that is now 60% LTV on a higher valuation may also move into a better product band — that is a reason to look, not a reason to assume a cheaper rate exists.

Revaluing on a commercial basis

This is the decision that changes borrowing the most. A bricks-and-mortar valuation treats the house like a large dwelling and cross-checks room rents. A commercial (investment) valuation capitalises the accepted rent after voids, management and running costs. On a well-let 7+ bedroom or sui generis house the income figure can sit above the vacant-possession comparable — and that is the figure the new lender will lend against.

Not every remortgage lender will take an income basis. Confirm the method before you instruct. Read how HMOs are valued if you are unsure which basis you are on today. A down-valuation happens when the surveyor strips out rooms that fail size, licence or fire tests, or when the rent evidence is weaker than the schedule you sent. Challenge with comparables if the facts are wrong; do not argue a brochure yield. A hybrid instruction — bricks-and-mortar with an income cross-check — is common on mid-size houses; the lender still lends on the lower of the two figures unless the product says otherwise.

Criteria for an HMO remortgage

The new lender looks at the house as it is let today, not as you hoped it would let when you bought it. Typical tests:

• A licence in date, or a renewal already lodged, matching the occupancy you are stressing.
• Lawful planning use (C4 or sui generis) and any occupancy cap on the permission.
• Fire precautions and a risk assessment that match the current layout.
• A room-by-room rent roll the valuer can evidence locally.
• Interest cover on the new lender’s stress rate. This page does not invent a single ICR. The Mortgage Works publishes 175% ICR for all HMO applications (intermediary HMO criteria, checked 22 October 2026). Other remortgage lenders on our panel do not publish one HMO ICR on the pages cited.
• LTV on the new valuation — plan for 75% unless a named product’s own page says otherwise.
• Your experience and, for a company, the SPV documents and guarantees.

A lapsed licence is a common decline. So is a house that has drifted to more occupiers than the permission allows. Fix those before you apply. Personal credit still matters if the stressed rent is tight or you want to raise a large amount of capital.

Costs: ERCs, fees, valuation

Early repayment charges are set on your current offer. They are often a percentage of the balance in each year of a fix (commonly stepping down, for example 5% then 4% then 3% — check the deed, do not assume). Leaving six months early on a £400,000 balance at 3% is £12,000 before you have paid the new lender. That can wipe out a 0.5% rate cut.

New-lender costs typically include an arrangement fee (often a percentage of the new loan, sometimes a fixed fee), a valuation, legal fees, and a broker fee if one applies. Valuation cost rises with size and with a commercial instruction. There is no unsourced “from 4.8%” on this page. Use the remortgage calculators as a sketch, then a dated illustration.

Add the costs up over the new fix, not the first month. A fee-free product with a higher rate can still be cheaper than a 2% arrangement fee on a short remaining hold.

Raising capital for the next HMO

Capital raising is a remortgage at a higher balance, capped by the new LTV and the stressed rent. If the house is now worth more on an income valuation, the extra headroom is what funds the deposit on the next purchase. Lenders will ask what the money is for. “Further HMO investment” is a normal answer; they may still want to see that the existing house still covers the new loan on its own rent.

Do not raise capital against a house that cannot pass a licence inspection. The new lender’s valuer will walk the same rooms. A missing fire door on the current HMO will stall the loan you wanted for the next one.

Portfolio landlords sometimes remortgage one house at a time rather than the whole book. That keeps ERCs isolated and lets you pick the valuation method per property. If you raise capital from three houses in the same quarter, the new lenders will see the extra borrowing on the other charges. Sequence the applications so each house still covers its own loan.

Use released cash for a deposit, not as a substitute for a void reserve on the house you just remortgaged. A capital raise that leaves the first HMO with no cash buffer is how people end up on a further advance they cannot service.

Product transfer vs remortgage

A product transfer is a new deal with your current lender, usually without a full valuation or legal work. It is faster and cheaper in fees. It will not normally revalue the house, will not release capital, and will not move you onto a commercial basis if you are stuck on bricks-and-mortar. Use it when rates is acceptable and you do not need cash. Some lenders will only transfer if the licence and occupancy are unchanged; a house that has added rooms since the last offer may be forced onto a full remortgage anyway.

A full remortgage to a new lender costs more in fees and takes longer, but it is how you change valuation method, raise capital, or leave a lender that no longer likes the occupancy. Compare both. A transfer that looks cheaper in week one can be the wrong choice if you need £80,000 out for the next deposit.

How to remortgage: steps and timeline

A straightforward licensed remortgage often takes four to eight weeks from a complete pack. A commercial revaluation, a licence renewal or a capital raise can run longer. Work in this order:

1. Read the current offer: ERC end date, remaining balance, and whether a transfer is even available.
2. Reconcile licence occupancy, planning use and the rent roll you will send.
3. Decide whether you need a bricks-and-mortar or income valuation — and whether the target lender will take it.
4. Model fees, ERC and the new stress test. Use the remortgage calculators as a sketch.
5. Apply, instruct the valuer the lender names, and keep the licence and fire pack ready for the solicitor.

Start three to six months before the fix ends. There is no charge for an initial remortgage review. If the valuer is going to take an income basis, put the last 12 months of rent, the tenancy type (joint or room-by-room) and the fire risk assessment in the pack on day one. Missing those is the usual four-week delay.

Is it hard to remortgage an HMO? It is harder than a single-let switch because the licence, planning and fire pack have to match the current let. A licensed six-bed with a clean rent roll is routine. A 12-bed that has drifted off its permission is a project, not a product transfer.

Check how this affects your HMO mortgages enquiry. Tell us the remaining ERC, the licensed occupancy and whether you want to raise capital or only switch rate, so we do not send a capital-raise on a commercial valuation to a product-transfer desk. Your property may be repossessed if you do not keep up repayments on a mortgage or any other debt secured on it.
