HMO Finance & Mortgages UK 2026 | Broker Guide

HMO Mortgage Types Explained

HMO mortgages are specialist products — most high street lenders will not touch them. Understanding the landscape helps you negotiate better terms and avoid wasting time on unsuitable applications.

Standard HMO mortgage

Available for properties with 3–6 bedrooms let to unrelated tenants. Rates are typically 0.5–1.5% above standard BTL. Minimum 25% deposit, with most lenders requiring the property to already have an HMO licence.

Large HMO mortgage (7+ beds)

Properties with 7 or more bedrooms require mandatory licensing and are classed as large HMOs. Fewer lenders operate here, but rates are competitive for experienced landlords. Expect 25–30% deposit minimum.

Bridging loans

Short-term finance (1–24 months) used to purchase and refurbish properties before refinancing onto a term mortgage. Rates from 0.55% per month. Essential for auction purchases and conversion projects.

Refurbishment finance

A hybrid between bridging and development finance. Funds are released in stages as refurbishment milestones are completed. Ideal for HMO conversions where costs are spread over the project timeline.

Portfolio lending

Lenders who will finance multiple HMOs under a single facility. Simplifies management and can offer better rates at scale. Typically requires 4+ properties and a proven track record.

Current HMO Mortgage Rates and Criteria

HMO mortgage rates fluctuate with the base rate and lender appetite. These are indicative ranges for 2026 — always get a personalised quote from a broker.

Product	Typical Rate / Criteria
Standard HMO mortgage (75% LTV)	5.0–6.5% fixed (2–5 year terms)
Large HMO mortgage (70–75% LTV)	5.5–7.0% fixed
Bridging loan (up to 75% LTV)	0.55–0.95% per month
Refurbishment finance	0.65–1.0% per month + arrangement fees
Minimum deposit	25% (some lenders accept 20% for experienced landlords)
Minimum personal income	£25,000+ (varies by lender, some have no minimum)
Stress test rate	Typically 5.5–7.0% depending on lender

Rates are indicative for Q1 2026. HMO mortgages are assessed on rental income coverage (typically 125–145% at the stress test rate), not personal income. Limited company borrowing is standard.

Bridging Loans for HMO Projects

Bridging finance is the engine behind most HMO conversion projects. Understanding how it works prevents costly surprises.

A bridging loan provides short-term capital to purchase a property, fund the conversion or refurbishment, and hold it until you can refinance onto a cheaper long-term mortgage. The typical cycle is: buy with a bridge at 70–75% of purchase price, complete the works, get the property revalued, then refinance at 75% of the new (higher) value — often pulling out most or all of your original cash.

Costs add up quickly with bridging finance. Beyond the monthly interest rate (0.55–0.95%), expect arrangement fees of 1–2% of the loan, valuation fees of £500–£1,500, legal fees for both your solicitor and the lender's, and potentially exit fees. On a £200,000 bridge, total costs over 6 months can reach £15,000–£25,000.

The key risk is the exit. If your refurbishment takes longer than planned, or the revaluation comes in lower than expected, you may need to extend the bridge (at additional cost) or inject more capital to refinance. Always build a 20% contingency into your timelines and budgets.

Golden rule: never take a bridging loan without a clear, realistic exit strategy. Know your target revaluation figure and have a mortgage broker confirm the refinance is achievable before you commit.

Refinancing Your HMO Portfolio

Refinancing is how experienced HMO investors recycle capital and grow their portfolios. Here is what to consider at each refinance point.

Get a RICS valuation early — request a desktop valuation before committing to a full application to gauge likely figures

Time your refinance with your bridge expiry — allow 8–12 weeks for the mortgage application process

Maximise your revaluation by ensuring all works are completed, the property is fully tenanted, and rooms are dressed

Consider fixed vs variable — a 5-year fix offers certainty but limits your flexibility to refinance again

Compare product fees vs rates — a lower rate with a 2% arrangement fee may cost more than a slightly higher rate with no fee

Review your corporate structure — refinancing is a good trigger to review whether your properties should be in personal name or a limited company

Check for early repayment charges on your existing mortgage before switching lenders

How to Choose an HMO Mortgage Broker

A specialist broker is essential for HMO finance. High street mortgage advisors rarely have access to the specialist lenders you need.

HMO-specific experience

Ask how many HMO mortgages they arrange monthly. A good HMO broker places 10+ per month and has direct relationships with specialist lenders who do not appear on comparison websites.

Whole of market access

Ensure your broker is not tied to a small panel. Whole-of-market brokers can access 50+ lenders including private banks, building societies, and specialist HMO lenders.

Fee transparency

Broker fees typically range from £500 to £1,500 per mortgage. Some charge a percentage of the loan. Clarify whether they also receive commission from the lender and how that affects their recommendations.

FCA regulated

Your broker must be FCA authorised. Check the FCA register at register.fca.org.uk. They should also have professional indemnity insurance and be a member of a recognised network.

Personal Name vs Limited Company for HMO Finance

This decision affects your mortgage options, tax liability, and long-term flexibility. Most new HMO investors are now purchasing through limited companies.

Personal name

Simpler administration and lower accountancy costs. Full mortgage interest was historically deductible, but Section 24 now restricts this to a 20% tax credit. Higher rate taxpayers are significantly impacted.

Best for: Landlords with 1–2 properties who are basic rate taxpayers and want simplicity

Limited company (SPV)

Corporation tax at 25% with full mortgage interest deductibility. More lenders now offer competitive company rates. Profits can be retained for reinvestment without personal tax. Slightly higher admin and accountancy costs.

Best for: Portfolio landlords, higher rate taxpayers, and anyone planning to scale

Frequently asked questions

Can I get a mortgage on an HMO property?

Yes, but you need a specialist HMO mortgage — most high street lenders do not offer them. HMO mortgages are available from specialist buy-to-let lenders, building societies, and private banks. A specialist broker is the best route to finding the right product for your situation.

How much deposit do I need for an HMO mortgage?

Most HMO lenders require a minimum 25% deposit (75% LTV). Some will accept 20% for experienced landlords with a proven track record. For large HMOs (7+ bedrooms) or properties in certain locations, 30% may be required.

Should I use a bridging loan to buy my HMO?

Bridging loans are ideal for properties that need refurbishment before they can be mortgaged — such as conversions from a single dwelling to an HMO. If the property is already a licenced, tenanted HMO, a standard HMO mortgage is cheaper and simpler. Always have a clear exit strategy before taking a bridge.

What does an HMO mortgage broker charge?

Typical broker fees range from £500 to £1,500 per mortgage arrangement, though some charge a percentage of the loan (0.5–1%). Many brokers also receive commission from the lender. A good broker saves you significantly more than their fee through access to better rates and products.
