Limited Company HMO Mortgage: Complete Guide (2026)

Buying an HMO through a limited company has become the default strategy for a growing number of portfolio landlords — and for good reason. Since the phased introduction of Section 24, higher-rate taxpayers holding properties in their personal name have seen their effective tax burden rise substantially. For HMO investors generating above-average rental yields, the numbers can be particularly painful.

This guide covers everything you need to know about limited company HMO mortgages: how they work, which lenders offer them, what rates you can expect, and — critically — when a company structure actually makes sense for your HMO investment.

We compare lenders and products to help you make informed decisions. For mortgage arrangement, speak to a qualified broker.

What Is a Limited Company HMO Mortgage?

A limited company HMO mortgage is a buy-to-let mortgage taken out by a company (usually an SPV — Special Purpose Vehicle) rather than an individual. The company owns the property, receives the rental income, and makes the mortgage repayments.

In practical terms, the mortgage works much the same as a personal HMO mortgage. The property is the security. The lender assesses rental coverage, LTV, and borrower experience. However, the legal and tax structure sits with the company rather than the individual.

Most lenders require the company to be a UK-registered limited company, and many insist on an SPV structure — meaning the company's sole purpose is holding property. Trading companies with broader activities can access HMO finance, but the lender pool is smaller.

The key distinction from a standard buy-to-let mortgage is that HMO-specific lending criteria still apply. The lender assesses the property as an HMO — bed count, licensing status, fire safety compliance, rental income on a per-room basis — regardless of whether the borrower is an individual or a company. You are combining two layers of specialist lending: company structure and HMO property type.

This dual specialism means the lender pool is narrower than either a standard company BTL mortgage or a personal-name HMO mortgage. Not every lender that does company lending will accept HMOs, and not every HMO lender will accept company applications. The overlap — lenders who do both — is where you need to focus your search.

Why Use a Limited Company for HMO Investment?

The decision to use a limited company almost always starts with tax. Three factors dominate:

Section 24 — Mortgage Interest Relief Restriction

Since April 2020, individual landlords can no longer deduct mortgage interest as a business expense under Section 24 of the Finance (No. 2) Act 2015. Instead, they receive a basic-rate (20%) tax credit. For higher-rate (40%) and additional-rate (45%) taxpayers, this creates a significant increase in the effective tax bill.

Limited companies are not affected by Section 24. A company can still deduct mortgage interest as a legitimate business expense before calculating corporation tax.

For HMO investors, this matters more than it does for standard BTL landlords. HMOs generate higher gross rents — typically £2,500 to £4,000+ per calendar month for a 6-bed property — which means the mortgage interest is a larger absolute figure and the Section 24 restriction bites harder.

Corporation Tax vs Income Tax

In 2026, corporation tax rates are 19% on profits up to £50,000 (small profits rate) and 25% on profits above £250,000, with marginal relief between those thresholds. Compare that with personal income tax at 20%, 40%, or 45%.

For higher-rate taxpayers, the difference between 19% corporation tax and 40% income tax on rental profits is stark — especially when you add the Section 24 restriction on top.

Mortgage Interest as a Deductible Expense

Within a limited company, mortgage interest remains fully deductible against rental income. This is the single biggest practical difference between personal and company ownership for leveraged HMO investors.

A worked example: if your 6-bed HMO generates £3,000 pcm rent and your mortgage costs £1,200 pcm, a limited company pays corporation tax on £1,800 pcm profit. A higher-rate personal taxpayer pays income tax on the full £3,000 pcm, with only a 20% tax credit on the £1,200 interest.

The compounding effect over a portfolio is dramatic. An investor with five HMOs generating £3,000 pcm each could be paying £40,000+ per year more in tax under personal ownership than through a limited company structure. Even after accounting for corporation tax on retained profits and dividend tax on extraction, the net saving typically runs into tens of thousands annually.

It is worth noting that retained profits within the company can be reinvested — used as deposits for further acquisitions — without triggering the additional layer of personal tax. This creates a powerful compounding effect for portfolio builders who do not need to extract all profits immediately.

SPV vs Trading Company — Which Structure for HMOs?

SPV (Special Purpose Vehicle)

An SPV is a limited company set up solely to hold property. Its articles of association restrict its activities to property investment, and its SIC codes reflect this (typically 68100 — buying and selling of own real estate, or 68209 — other letting and operating of own or leased real estate).

Most HMO mortgage lenders prefer SPVs because the simplicity of the structure makes underwriting straightforward. There are no trading liabilities, no complex accounts, and the property is the company's only asset.

Trading Company

A trading company is one that carries on a broader business — perhaps a lettings agency, a construction firm, or any other commercial activity. Some HMO investors already have a trading company and want to purchase property through it.

Fewer lenders accept trading company applications for HMO mortgages. Those that do will typically want to see:

At least two years of filed accounts
A clean balance sheet
Evidence that the company's trading activities do not create undue risk to the mortgage

Which Should You Choose?

For most HMO investors, an SPV is the simpler and more widely accepted route. The lender pool is larger, the application process is faster, and lenders are comfortable with newly incorporated SPVs (unlike trading companies, where a track record is expected).

If you already hold property through a trading company and want to keep everything under one roof, speak to a specialist broker about which lenders will accommodate this.

One important practical note: some investors set up a new SPV for each property purchase. Others hold multiple HMOs within a single SPV. The single-SPV approach is simpler and cheaper to administer, but means all properties share the same corporate entity — and the same liabilities. Multiple SPVs ring-fence each asset but multiply the accountancy, filing, and bank account costs. There is no universally right answer; it depends on portfolio size, risk tolerance, and administrative capacity.

Limited Company HMO Mortgage Rates — How They Compare to Personal Name

Historically, limited company mortgage rates carried a premium of 0.5% to 1.0% over equivalent personal-name products. That gap has narrowed significantly as more lenders have entered the company BTL market.

In 2026, the picture looks roughly like this:

Structure	Typical 2-Year Fixed Rate (75% LTV)	Typical 5-Year Fixed Rate (75% LTV)
Personal name	4.5% – 5.5%	4.8% – 5.8%
Limited company (SPV)	4.8% – 6.0%	5.1% – 6.3%

The premium exists because lenders face slightly higher administrative costs (company searches, personal guarantee documentation) and perceive marginally higher risk from corporate structures.

However, the after-tax cost of borrowing through a limited company is often lower than borrowing personally — particularly for higher-rate taxpayers. It is the net cost, not the headline rate, that matters.

Lender Criteria for Limited Company HMO Mortgages

Lender criteria for company HMO mortgages are broadly similar to personal-name HMO mortgages, with some additional requirements:

Bed Count Limits

Most lenders cap at 6 beds for standard HMO mortgage products — the same limit that applies to personal-name lending. Above 6 beds, you are typically looking at specialist or commercial lenders, regardless of ownership structure.

Some lenders will go to 8, 10, or even 15+ beds through a limited company, but expect higher rates and lower LTV.

Experience Requirements

Lenders typically want to see that the company directors have property investment experience. Requirements vary:

Minimum: Some lenders accept first-time landlords in a limited company (with conditions)
Standard: 12–24 months' experience as a landlord
Specialist: For larger HMOs (7+ beds), most lenders want demonstrable HMO management experience

Personal Guarantees

Almost all limited company HMO mortgages require personal guarantees (PGs) from the company directors. This means the directors are personally liable for the mortgage debt if the company defaults.

PGs effectively negate the limited liability benefit of the company structure — but the tax advantages remain. Do not enter a limited company HMO mortgage expecting limited liability on the debt.

Minimum and Maximum Loan Size

Some lenders set minimum loan sizes for company lending — typically £75,000 to £100,000. Maximum loan sizes vary widely, from £500,000 with high-street adjacent lenders to £5m+ with specialist lenders.

LTV Limits

Most limited company HMO mortgages are available up to 75% LTV. A smaller number of lenders will stretch to 80% for SPVs with experienced directors. Below 65% LTV, you may unlock better rates.

Which Lenders Offer Limited Company HMO Mortgages?

The market has expanded considerably. A non-exhaustive overview of lender types:

Lender Type	Typical LTV	Bed Count	Notes
High-street adjacent (e.g. BM Solutions, The Mortgage Works)	Up to 75%	Up to 6 beds	Competitive rates, stricter criteria
Specialist BTL (e.g. Paragon, Landbay, Fleet)	Up to 75%	Up to 8–10 beds	Flexible on experience, slightly higher rates
Commercial/specialist (e.g. Shawbrook, Together, Aldermore)	Up to 70%	10+ beds	Higher rates, accommodate complex situations
Private banks	Up to 65%	Case-by-case	Bespoke terms, high minimum loan

It is worth emphasising that lender panels change frequently. Products are withdrawn and launched regularly, and a lender that was competitive six months ago may no longer be the best option. This is one area where working with a broker who actively monitors the company HMO lending market pays for itself — they can identify the best current options far more efficiently than an individual investor searching independently.

Some lenders also distinguish between new-purchase and remortgage applications for limited companies. If you are remortgaging an existing HMO into a company (a common scenario when restructuring a portfolio), the available products may differ from those offered for a straightforward purchase.

How HMO Property Size Affects Limited Company Lending

The number of bedrooms in your HMO directly affects which lenders will consider the case — and this applies equally whether you are borrowing personally or through a company.

3–6 Bed HMOs

Most lenders treat these as standard residential HMO mortgages. The widest product range, most competitive rates, and standard residential valuations (bricks and mortar).

7+ Bed HMOs (Large HMOs / Sui Generis)

Above 6 beds, the property typically requires a mandatory HMO licence (rather than additional licensing, which varies by council). Many lenders reclassify properties of this size as semi-commercial or commercial, which means:

Commercial valuation — the surveyor values based on rental yield rather than comparable sales
Fewer lenders — the panel narrows significantly
Different LTV limits — often capped at 65–70%
Higher rates — reflecting the specialist nature of the lending

For limited company borrowers, the impact is compounded: you are combining a company structure (which already narrows the lender pool) with a larger HMO property (which narrows it further). Working with a broker who understands both dimensions is essential.

Setting Up an SPV for HMO Investment — Step by Step

Setting up an SPV is straightforward:

1. Incorporate the Company

2. Choose the Right SIC Codes

Use property-related SIC codes. The most commonly used for HMO SPVs are:

68100 — Buying and selling of own real estate
68209 — Other letting and operating of own or leased real estate
68320 — Management of real estate on a fee or contract basis

Stick to property-related codes. Lenders will check, and non-property SIC codes can cause applications to be declined.

3. Set Up a Company Bank Account

You will need a business bank account for rental income and mortgage payments. Most high-street banks offer business accounts, though some are more amenable to property SPVs than others.

4. Appoint Directors and Shareholders

For most HMO SPVs, the directors and shareholders are the individual investors. If purchasing with a partner or business associate, agree the shareholding structure at this stage.

5. Prepare Your Articles of Association

Standard Companies House model articles are usually sufficient for a property SPV. However, some investors choose bespoke articles that restrict the company's activities to property investment — which some lenders prefer to see. Your solicitor or accountant can advise on whether standard or bespoke articles are more appropriate for your situation.

6. Get Your Accountant Involved Early

An accountant familiar with property SPVs can advise on optimal shareholding structures, dividend extraction strategies, and annual filing requirements. This is not a DIY exercise for most investors.

Key questions for your accountant include: how to structure shareholdings between partners or spouses for tax efficiency, whether to pay yourself a salary or dividends (or a combination), how to handle director's loan accounts if you inject personal funds, and how to plan for future growth if you intend to acquire multiple HMOs through the same or different SPVs.

7. Apply for the Mortgage

With the SPV incorporated and your accountant on board, you can proceed with the mortgage application. Most lenders will accept applications from newly incorporated SPVs — there is no requirement for the company to have trading history, provided the directors have personal property experience.

Costs of Running an HMO Through a Limited Company

Operating through a company adds administrative and professional costs that do not apply to personal-name ownership:

Cost	Typical Annual Amount
Accountancy fees (annual accounts + CT return)	£500 – £1,500
Confirmation statement (Companies House)	£13
Company bank account	£0 – £15/month
Registered office service (if not using home address)	£50 – £150
Payroll (if extracting salary)	£100 – £300

These costs are tax-deductible within the company. However, they need to be factored into your cashflow modelling — particularly if you are operating a single-property SPV where the fixed costs are spread across only one income stream.

Use the HMO cashflow calculator to model company running costs against rental income.

When a Limited Company Doesn't Make Sense for HMO Investment

A limited company is not always the right structure. Consider these scenarios:

Basic-Rate Taxpayers

If your total income (including rental profits) keeps you in the basic-rate band, the Section 24 restriction has minimal impact. You are paying 20% income tax and receiving a 20% tax credit on mortgage interest — effectively neutral. The administrative costs and rate premium of a limited company may outweigh the tax saving.

Cash Purchases

If you are buying without a mortgage, Section 24 is irrelevant (there is no mortgage interest to restrict). The only tax advantage of a company is the corporation tax rate itself — which may or may not outweigh the costs and complexity.

Existing Personally-Held Portfolios

Transferring existing properties into a limited company triggers capital gains tax, stamp duty on the transfer, and potential early repayment charges on existing mortgages. The upfront cost can be substantial and may take years to recoup through tax savings.

Single Property Investors

The fixed costs of running a company (accountancy, filing, admin) are the same whether you own one property or twenty. For single-property investors, these costs may erode the tax advantage.

Short-Term Holds

If you plan to buy, refurbish, and sell within 1–3 years, the company structure adds complexity to the disposal. Profits from property sales within a company are subject to corporation tax, and extracting the proceeds triggers further tax (dividends or winding up the company). For short-term projects, personal ownership or a different structure may be more efficient.

For a detailed comparison, read our SPV vs personal name HMO guide.

Transferring Existing HMOs Into a Limited Company

If you already own HMOs in your personal name and want to move them into a company, the process involves:

1. Selling to the Company

Legally, you are selling the property from yourself to your company. This is a disposal for CGT purposes and an acquisition for stamp duty purposes.

2. Capital Gains Tax

You will pay CGT on any gain since you acquired the property. Lettings relief and annual exemptions may reduce the liability, but for most HMO investors with significant equity growth, the CGT bill will be material.

3. Stamp Duty

The company will pay stamp duty (SDLT) on the purchase price — including the 5% additional property surcharge that applies to company purchases. On a £300,000 HMO, stamp duty could be £17,500 or more.

4. Mortgage Considerations

Your existing personal mortgage will need to be redeemed. The company will need its own mortgage. Early repayment charges may apply on the personal mortgage.

5. Incorporation Relief

In some cases, HMRC may grant incorporation relief under Section 162 TCGA 1992, which can defer (not eliminate) the CGT liability. This typically requires the property business to be run as a genuine going concern. Professional advice is essential.

6. Timeline

The entire transfer process — from instructing solicitors to completing the company mortgage — typically takes 3–6 months. During this period, you may be running two mortgages simultaneously (or bridging the gap), which adds to the cost. Factor this holding period into your financial modelling.

Is It Worth It?

The decision to transfer depends entirely on the numbers. If you are a higher-rate taxpayer with a large remaining mortgage term and modest capital gains, the tax saving over the remaining ownership period can substantially exceed the transfer costs. If you have significant gains and are close to paying off the mortgage, the upfront costs may never be recouped.

As a rule of thumb, the transfer is more likely to make financial sense when: the property has been held for a shorter period (lower CGT liability), the remaining mortgage term is long (more years of tax savings), and your marginal tax rate is 40% or above. Model the specific numbers with your accountant before proceeding.

FAQs

Can I get an HMO mortgage through a limited company as a first-time landlord?

Yes, although the lender pool is more limited. Several specialist lenders accept first-time landlords borrowing through an SPV, provided the rental coverage is strong and the LTV is conservative (typically 70% or below). Some lenders may require you to have owned your own residential property, even if you have not previously been a landlord.

Are limited company HMO mortgage rates higher than personal name rates?

Generally, yes. The premium is typically 0.3% to 0.5% on like-for-like products, though the gap has narrowed in recent years. However, the after-tax cost of borrowing through a company is often lower for higher-rate taxpayers, making the headline rate comparison misleading in isolation.

Do I need a personal guarantee for a limited company HMO mortgage?

Almost always, yes. The vast majority of buy-to-let lenders require personal guarantees from all directors with a 25%+ shareholding. This means the directors are personally liable for the mortgage debt if the company cannot repay. Very few lenders offer non-recourse lending to SPVs.

Can I transfer my existing HMO into a limited company?

Yes, but the process involves selling the property from yourself to the company. This triggers capital gains tax on any gain, stamp duty on the purchase, and potentially early repayment charges on your existing mortgage. The costs can be significant and should be modelled carefully against the projected tax savings of company ownership before proceeding.

What SIC codes should my SPV use for HMO investment?

The most commonly used SIC codes for property SPVs are 68100 (buying and selling of own real estate), 68209 (other letting and operating of own or leased real estate), and 68320 (management of real estate on a fee or contract basis). Stick to property-related codes — lenders check SIC codes during underwriting and may decline applications where the company appears to have non-property activities.
