Limited company buy-to-let mortgages: How they work

A limited company can potentially take out a mortgage to buy a rental property. The company becomes the borrower and normally owns the property, but lenders may still assess the directors and shareholders behind it.
Limited company buy-to-let borrowing can differ from buying personally. Lenders may have requirements around the company structure, expected rent, deposit, property and the applicants involved. The available products and costs can differ too.
From a mortgage point of view, we wouldn’t assume that incorporating automatically gives you a better mortgage. The ownership structure also has tax and accounting implications, so it’s important to consider those separately with a qualified accountant or tax adviser.
If you’re considering buy-to-let mortgages, this guide explains how company applications work, what lenders may assess and what to check before committing to a property.
What is a limited company buy-to-let mortgage?
A limited company buy-to-let mortgage is a loan taken out by a company to purchase or refinance a property that will be rented to tenants.
In a typical arrangement:
- The limited company is the mortgage borrower.
- The company purchases and owns the property.
- The mortgage is secured against that property.
- Rent is paid to the company.
- The company makes the mortgage payments.
- Directors or shareholders may provide personal guarantees.
Although the mortgage is in the company’s name, lenders don’t necessarily assess the company in isolation. They may also look at the directors, shareholders and anyone providing a guarantee.
Some investors use a special purpose vehicle, usually shortened to SPV. An SPV is a limited company created for a specific purpose, such as owning and letting property. Some lenders accept only certain company activities or structures, while others have broader criteria.
An SPV buy-to-let mortgage isn’t the only possible route. Whether you can use a new SPV, an established property company or an existing trading business depends on the lender.
Can a limited company get a buy-to-let mortgage?
Yes, subject to the lender’s criteria.
The mortgage market includes lenders that accept limited companies, including newly formed SPVs. However, each lender can set its own requirements for the company, the people behind it and the proposed investment.
A lender may consider:
- The company’s structure and registered activities
- Its directors and shareholders
- The personal credit histories of the applicants
- Existing personal and business borrowing
- Previous landlord experience, where required
- The property type and condition
- The expected monthly rent
- The requested loan-to-value
- The source of the deposit
- The lender’s rental affordability calculation
- Whether personal guarantees will be provided
From a mortgage point of view, we’d look at both the company and the people behind it. Setting up a new company doesn’t mean the lender ignores your personal circumstances.
A new SPV may not need the same trading history as an ordinary operating business. However, this doesn’t make every newly incorporated company acceptable to every lender. The company’s ownership, activities and directors can still affect the buy-to-let mortgage options available.
How much deposit does a limited company need for buy-to-let?
Buy-to-let mortgages usually require a larger deposit than standard residential mortgages. Many products are available at loan-to-values of around 75%, which would mean providing a 25% deposit, but this isn’t a universal minimum.
Some lenders may accept a smaller deposit, while others may require more because of the property, applicant, company structure or wider circumstances.
For example:
| Purchase details | Amount |
|---|---|
| Property price | £250,000 |
| Deposit at 25% | £62,500 |
| Mortgage required | £187,500 |
| Loan-to-value | 75% |
Loan-to-value, or LTV, is the mortgage amount expressed as a percentage of the property’s value. In this example, borrowing £187,500 against a £250,000 property produces an LTV of 75%.
The size of your buy-to-let deposit affects the LTV and can influence which products are available. Our guide to how much deposit you need for a mortgage explains the relationship between the deposit, mortgage and property value in more detail.
Having enough deposit doesn’t necessarily mean you can borrow the remaining amount. The expected rent must also satisfy the lender’s affordability calculation.
When we’re looking at a limited company BTL case, we’d check the deposit and its source alongside the rent and requested loan. That helps identify potential issues before an application is submitted.
How do lenders work out how much a limited company can borrow?
Buy-to-let affordability is usually based heavily on the property’s expected rental income. It isn’t simply calculated as a multiple of the directors’ salaries.
Lenders commonly use an Interest Coverage Ratio, or ICR, to assess whether the rent provides sufficient coverage for the mortgage interest. They may test the mortgage using an assumed interest rate rather than the actual initial rate offered.
The exact calculation varies between lenders. It can also depend on factors such as:
- The mortgage product
- Whether the mortgage is fixed or variable
- The applicant’s tax position
- The company structure
- The property type
- Whether personal income is being considered
The Bank of England’s current buy-to-let underwriting standards expect relevant lenders to assess affordability using an ICR test and/or a personal-income affordability test where appropriate. They should also consider costs associated with the property rather than relying on its equity or possible future price growth.
Some lenders offer a form of top slicing, where personal income may be considered if the rent doesn’t fully support the requested mortgage. This isn’t available in every case, and the lender will normally want to assess whether the applicant’s personal finances can support the shortfall.
If someone came to us with a £250,000 property and expected rent of £1,400 a month, we wouldn’t look at the purchase price alone. We’d check how the rent performs under the lender’s own BTL stress test and whether it supports the loan they’re asking for.
You can use our buy-to-let mortgage calculator to estimate rental yield, cash flow and rental cover before looking at individual lender criteria. The result is an estimate rather than a mortgage offer because each lender can use a different calculation.
Do you need an SPV for a limited company BTL mortgage?
Not necessarily. An SPV is one form of limited company, but the two terms aren’t interchangeable.
The important distinction is usually between a company established specifically to hold property and a business that carries out other commercial activities.
New SPV
A new SPV is created specifically to own and let property. It may have little or no trading history when the mortgage application is made.
Some lenders are comfortable with newly formed SPVs, provided the company’s structure, registered activities, directors and shareholders meet their criteria.
Existing trading company
An existing trading company is already carrying out another type of business. For example, it may provide professional services, operate a shop or run a construction business.
Using that company to purchase a rental property can be a different lending proposition. Some lenders don’t accept trading companies for buy-to-let borrowing, while others may consider them subject to further assessment.
Before researching lenders, we’d want to establish which structure is being used and what the company currently does. We wouldn’t recommend creating or restructuring a company solely because a general article suggests that an SPV is preferable.
The company should also make sense from a legal, accounting and tax perspective.
Do lenders check the company directors?
Yes. A limited company may be the named borrower, but lenders commonly assess its directors and, in some cases, shareholders.
Depending on the lender, the checks may include:
- Personal credit history
- Age
- Residential status
- Personal income
- Existing mortgages and other borrowing
- Previous landlord experience
- Other directorships
- Shareholding in the borrowing company
- Ownership of other buy-to-let properties
Directors may also be asked to give personal guarantees. This can make them personally responsible if the company doesn’t meet its mortgage obligations, subject to the wording and enforceability of the guarantee.
The people who need to be included in an application can vary according to the company’s ownership. A lender might accept a simple structure with two directors differently from a company involving several shareholders, another company as a shareholder or a more complicated group arrangement.
This is why limited company buy-to-let mortgage criteria should be checked against the actual company rather than assumed from a headline product description.
Are limited company buy-to-let mortgage rates higher?
Limited company buy-to-let mortgage rates can differ from those available to landlords borrowing personally. The range of lenders and products can differ as well.
However, the interest rate alone doesn’t show the full cost of a mortgage. When comparing options, we’d also look at:
- Product fees
- Valuation fees
- Legal costs
- Any separate lender or application fees
- The mortgage term
- Early repayment charges
- Whether fees are added to the loan
- The total cost during the initial product period
A product with the lowest advertised rate could be more expensive overall if it has a large fee. The effect can be particularly noticeable on a smaller mortgage, where the fee represents a larger proportion of the amount borrowed.
The appropriate comparison also depends on what you expect to do with the property. A landlord planning to hold it for many years may assess the options differently from someone expecting to sell or refinance relatively soon.
Limited company vs personal buy-to-let
There isn’t a universally better ownership structure. The mortgage, tax treatment, administration and investor’s longer-term plans all need to be considered.
| Consideration | Personal ownership | Limited company |
|---|---|---|
| Mortgage borrower | The individual | The company |
| Mortgage availability | Broad buy-to-let market | Specific company and SPV products |
| Underwriting | Individual, property and rent | Company, directors, property and rent |
| Taxation | Personal property-income rules | Company taxation rules |
| Administration | Generally simpler | Company accounts and administration required |
| Rental profits | Belong to the individual | Belong to the company |
| Taking money personally | Already received personally | Must be extracted from the company appropriately |
| Best option | Depends on the circumstances | Depends on the circumstances |
HMRC states that rental income from property owned by a company is counted as business income. It also confirms that UK resident companies aren’t affected by the residential property finance-cost restriction that applies to individual Income Tax payers.
That doesn’t mean buying through a company will automatically leave you better off. Corporation Tax, extracting money from the company, accountancy costs, Stamp Duty Land Tax and the eventual sale of the property can all affect the outcome.
The choice between buy-to-let in a limited company or personal name should therefore be considered with a qualified tax adviser. A mortgage adviser can assess whether each route is workable from a borrowing perspective, but that’s only one part of the decision.
What are the tax implications?
Rental profits earned by a company are generally taxed within the company rather than under the landlord’s personal property-income calculation. Companies pay Corporation Tax on their taxable profits, including relevant property or investment profits.
Finance-cost treatment also differs. HMRC’s rental-income guidance explains that UK resident and non-UK resident companies aren’t affected by the residential finance-cost restriction applied to individual landlords.
Other issues may include:
- Corporation Tax
- Tax when money is withdrawn from the company
- Stamp Duty Land Tax
- Tax on a future sale
- Accountancy and company administration costs
- The treatment of losses and allowable expenses
Monday Mortgages provides mortgage advice rather than tax advice. Before deciding whether to buy personally or through a company, we’d recommend discussing the ownership structure with a qualified accountant or tax adviser.
Can you transfer an existing buy-to-let property into a limited company?
Potentially, but transferring a buy-to-let property to a limited company isn’t simply an administrative change of name.
The company is a separate legal entity. Moving a personally owned property into it can amount to a transfer of ownership and may involve:
- Redeeming or replacing the existing mortgage
- A new mortgage application in the company’s name
- Conveyancing
- A new property valuation
- Stamp Duty Land Tax
- Capital Gains Tax considerations
- Other legal and accountancy work
An existing personal mortgage generally can’t just be renamed as a company mortgage.
Before proceeding, we’d want to check whether a suitable company mortgage is available and how much it could support. A solicitor and tax adviser should assess the legal and tax consequences separately.
Can you remortgage a limited company buy-to-let?
Yes, potentially. A limited company may be able to remortgage when an existing deal ends, move to another lender or release equity from a property.
A buy-to-let remortgage is likely to involve a fresh assessment. The lender may review:
- The current property value
- The achievable rent
- The outstanding mortgage
- The requested new loan
- The company structure
- The directors and shareholders
- The wider property portfolio
- Personal or business credit commitments
The amount originally borrowed isn’t necessarily the amount another lender will agree to refinance. Changes to the property value, rent, interest-rate stress test or lender criteria can all affect the result.
Any early repayment charges, arrangement fees, valuation costs and legal costs should be included when assessing whether switching is worthwhile.
Is a limited company BTL mortgage right for you?
The answer depends on both the mortgage and your wider financial plans.
Mortgage considerations
From a mortgage perspective, we’d look at:
- The available deposit
- The expected rent
- The amount you need to borrow
- The company structure
- The property type
- Your landlord experience
- The available lender options
- Product rates and fees
- Plans for future property purchases
Wider financial considerations
You should also consider:
- Personal and company taxation
- Accountancy and administration
- How rental profits will be used
- How money will be withdrawn from the company
- Future investment plans
- The eventual sale or transfer of the property
We’d assess whether the company structure works from a mortgage point of view, but we wouldn’t tell someone to incorporate purely for a perceived tax advantage. The ownership decision needs to make sense alongside independent tax and legal advice.
What we’d want to know before looking for a lender
Before comparing lenders, we’d first establish the company structure, deposit, expected rent and required loan. That normally tells us far more than simply searching for the lowest advertised limited company BTL rate.
We’d usually want to know:
- Whether you’re buying through a new or existing company
- The company number, if it has already been incorporated
- What the company currently does
- Who the directors and shareholders are
- The property purchase price
- How much deposit you have
- Where the deposit is coming from
- The expected monthly rent
- The mortgage amount required
- Whether the property is a standard rental, HMO or another specialist type
- Whether you already own rental properties
- Your personal income and employment position
- Your credit history
- Whether you’re a first-time landlord
- Your plans for the property and wider portfolio
If you’ve already found a property, we’d want to check whether the expected rent supports the borrowing before you commit significant money to the purchase.
Once those details are clear, we can compare suitable lender criteria, rental calculations and overall mortgage costs.
[FAQ]
Frequently asked questions
Can a new limited company get a buy-to-let mortgage?
Potentially, yes. Some lenders accept newly formed SPVs without an established trading history. They may still assess the company structure, directors, shareholders, property, rent, deposit and requested mortgage.
Do I need to own a home before getting a limited company BTL mortgage?
Not in every case. Some lenders require applicants or directors to own their own home, while others may consider non-homeowners. The available options depend on the wider application.
Can a first-time landlord use a limited company?
Potentially. Some lenders accept a first-time landlord mortgage through a limited company, while others require previous letting or property ownership experience. First-time landlords may therefore have a narrower lender choice.
How much deposit does a limited company need for buy-to-let?
A deposit of around 25% is common in the buy-to-let market, but it isn’t a universal requirement. The minimum can vary according to the lender, property, company, rental calculation and applicants.
Is an SPV the same as a limited company?
An SPV is a type of limited company established for a specific purpose. In this context, that purpose is normally holding and letting property. Not every limited company is an SPV because many companies carry out other trading activities.
Can I use my existing business to buy a rental property?
Possibly, but lender criteria for a trading company can differ from those for a property SPV. You should check the mortgage options and obtain tax and accounting advice before using an existing business to purchase property.
Are limited company buy-to-let mortgages regulated by the FCA?
The position depends on the transaction. Many business buy-to-let arrangements aren’t regulated in the same way as residential mortgages, while consumer buy-to-let business is covered by a separate framework. The FCA Handbook explains the distinction between buy-to-let and consumer buy-to-let lending. A mortgage adviser can confirm how the proposed arrangement is treated.
