Limited company versus personal ownership for HMOs

There are two broad routes to holding an HMO, and they lead to quite different mortgage and tax outcomes.

Personal ownership means you buy and hold the property in your own name, or jointly with a partner. The rental income is part of your personal income, and you borrow as an individual investor. It is simple to set up, with no company to run, and it suits some landlords well, particularly those with only one or two properties or those who are basic rate taxpayers.

Limited company ownership means a company owns the property, most commonly a special purpose vehicle, or SPV, whose only activity is holding and letting property. You are a director and shareholder, the company receives the rent and pays its own tax, and you borrow in the company name, usually with personal guarantees. Running a company adds administration and cost, but for many landlords, especially higher rate taxpayers or those building a portfolio, the structure can be more efficient.

Neither route is automatically better. The right answer depends on your tax position, how many properties you plan to hold, whether you need to draw the income now or reinvest it, and your longer term plans. Those are questions for a qualified accountant. What we can set out clearly is how the choice affects your finance options, which is where the decision often has an immediate, practical impact.

The single biggest driver behind the shift towards limited companies is how mortgage interest is treated for tax, and this is where the two routes diverge most sharply. We set this out in outline only, because the detail depends entirely on your circumstances and is a matter for your accountant.

For personal landlords, the rules known as Section 24 restrict the way mortgage interest is relieved. Rather than deducting finance costs from rental income before tax, individual landlords receive relief limited to the basic rate, given as a tax credit. For higher and additional rate taxpayers, this means the effective cost of their mortgage interest is higher than it was under the old rules, which can materially reduce the profit on a geared HMO.

For limited company landlords, mortgage interest is generally treated as a business expense and deducted from profit before the company is taxed, so the Section 24 restriction does not apply in the same way. For a higher rate taxpayer running a geared portfolio, that difference can be significant, which is a large part of why company ownership has become common among more active investors.

That said, a company brings its own tax considerations, from how profits are taxed to how you extract money from it, and these can offset the interest advantage depending on your situation. This is exactly the kind of trade off that needs proper advice. Please take it from a qualified accountant before deciding, because the right structure is genuinely personal to your finances and plans.

On the finance side, the ownership route determines the type of mortgage you apply for, and the two products behave differently.

A personal HMO mortgage is underwritten against you as an individual. The lender looks at your income, your experience, your credit profile and the property's rent. It is a familiar product, and for a landlord with a small number of properties held personally it is straightforward.

An SPV limited company HMO mortgage is made to the company, with you providing personal guarantees. Lenders that offer these are used to seeing a clean SPV, meaning a company set up purely to hold property, often identified by specific business activity codes. They will assess the company, its directors and shareholders, and the same rental affordability tests still apply. Setting the company up correctly from the outset matters, because lenders prefer a simple, dedicated SPV over a company with mixed trading activity, which can narrow your options.

• Personal: borrowing assessed against you as an individual, simple to arrange, well suited to smaller holdings.
• SPV company: borrowing made to a dedicated property company with personal guarantees, favoured by portfolio landlords, needs a clean company structure.

Both routes are well served in the HMO market, so the choice rarely comes down to whether finance is available. It comes down to which structure suits your tax position and plans, and then arranging the matching product.

A common worry is that borrowing through a company is harder or far more expensive. In today's market that is largely out of date. A large and growing share of buy to let and HMO lending is written to limited companies, and specialist lenders actively serve SPV borrowers, so availability is strong for both routes.

Pricing does differ, but usually by less than people expect. Historically, limited company products carried a modest premium over personal ones to reflect the extra work in assessing a company, and some of that gap remains, though competition has narrowed it. Across the HMO market, rates sit broadly in the 5.5% to 6.5% band and loan to value typically runs up to around 70% to 75%, for both personal and company borrowing. These are indicative figures, subject to status and valuation, and the exact rate depends on the property, the leverage, your experience and the lender rather than on ownership route alone.

The more meaningful difference is often in affordability rather than headline rate. As covered in our yields and affordability guide, limited company and basic rate borrowers are frequently assessed at a lower interest cover ratio, around 125%, while higher rate personal borrowers may face a tougher ratio, nearer 145%. That can mean a company borrower supports a larger loan against the same rent. It is one more reason the ownership decision and the finance decision are best considered together, with tax advice alongside.

Beyond rate and tax, there is the practical question of mortgageability, meaning how easily a property and structure can be financed and refinanced over time. Getting this right protects your flexibility for years to come.

A clean SPV tends to keep the most doors open. Because lenders like a simple, dedicated property company, an SPV set up purely to hold and let property, with the right business activity codes and clear ownership, is straightforward to lend against and to refinance later. A company with mixed activities, complex shareholdings or trading income can narrow the pool of willing lenders, which is worth avoiding if property is the goal.

Personal ownership is highly mortgageable for smaller holdings, but landlords sometimes find that as their portfolio and income grow, the tax position pushes them towards a company for future purchases, leaving them holding a mix of personal and company properties. Moving an existing personal property into a company later is not simply a transfer. It is usually treated as a sale to the company, which can trigger tax and costs, so it is a decision to weigh carefully with your accountant rather than assume you can undo later.

The sensible approach is to decide the structure with a clear view of where you are heading, take tax advice early, and then arrange finance that fits. We can talk through how each route affects your borrowing, availability and pricing, and help place the right product once you and your accountant have settled the structure. Regulated cases are referred to an authorised firm, and nothing here is financial, legal, planning or tax advice.

Pulling it together, the limited company versus personal decision for an HMO turns on a few linked questions. How is your rental profit likely to be taxed, given your other income? How many HMOs do you plan to hold, and are you building a portfolio or holding one or two? Do you need to draw the income now, or reinvest it and grow? And how does each route affect the finance you can access and afford? The tax questions belong with a qualified accountant, but the finance questions are ours to help with.

As a rough sense of the landscape, personal ownership often suits basic rate taxpayers and smaller holdings where simplicity is valuable, while limited company ownership often suits higher rate taxpayers and portfolio builders who benefit from the interest treatment and the affordability position. These are tendencies, not rules, and plenty of cases sit somewhere in between, which is exactly why individual advice matters rather than a blanket answer.

What we would encourage is to make the structure decision deliberately and early, with your accountant on the tax and us on the finance, before you commit to a purchase. Get both right and every HMO you buy sits on a sounder footing. We are happy to walk through the borrowing implications of each route for your situation and point you to lenders that fit once the structure is set.
