Limited company buy to let mortgage beneficial ownership new company is a specific type of landlord mortgage designed for investors purchasing or refinancing rental property through a newly formed limited company. This structure allows for beneficial ownership—where the individual controls the company and profits—even if the property is legally owned by the company. In 2025, this approach continues to grow in popularity due to tax advantages, portfolio flexibility, and evolving buy-to-let lending regulations. With rising interest rates and tighter affordability checks, landlords are increasingly turning to limited company structures to optimise investment property finance. This mortgage type is especially attractive to portfolio landlords seeking to mitigate the impact of Section 24 tax changes, streamline their finances, and scale their property businesses more efficiently.

Limited company buy-to-let mortgages often have slightly higher interest rates than personal name products, but they offer tax efficiencies and greater flexibility for long-term investors. These mortgages require strong rental income projections and compliance with affordability stress testing.
How This Mortgage Works
A limited company buy to let mortgage beneficial ownership new company is structured for landlords who purchase rental property through a special purpose vehicle (SPV) limited company. The beneficial owner is typically the director and shareholder of the company, meaning they control the property and receive profits, even though the legal title is held by the company.
These mortgages come in various forms, including fixed-rate, variable-rate, and tracker products. Fixed-rate options are popular in 2025 due to interest rate volatility, offering predictable monthly payments over 2, 5, or even 10 years.
This type of mortgage suits both first-time landlords and experienced portfolio investors who want to benefit from tax planning, asset protection, and streamlined portfolio management. Lenders typically require the limited company to be registered with Companies House and have SIC codes related to property letting (e.g., 68209).
Compared to standard residential mortgages, these products are underwritten based on rental income rather than personal income, and they involve more complex legal and underwriting processes. However, lender appetite for limited company buy-to-let lending remains strong in 2025, especially from specialist lenders.
Eligibility and Criteria
To qualify for a limited company buy to let mortgage beneficial ownership new company, applicants must meet both company and individual criteria. While the mortgage is in the company’s name, lenders assess the directors and shareholders as guarantors.
Income Requirements:
Most lenders do not require a minimum personal income, but some prefer directors to earn at least £25,000 annually. However, rental income is the primary basis for affordability.
Rental Coverage and Stress Testing:
Lenders assess the property’s rental income using an Interest Coverage Ratio (ICR). Typically, the rental income must cover 125% to 145% of the mortgage interest, stress-tested at 5.5% or higher. For higher-rate taxpayers or limited companies, the ICR threshold may be lower due to different tax treatments.
Property Type Restrictions:
Lenders may restrict certain property types such as HMOs (houses in multiple occupation), new-build flats, or ex-local authority homes. However, specialist lenders often accept these with stricter criteria.
Credit Score Expectations:
A clean credit history is preferred, though some lenders accept minor adverse credit. Directors with recent CCJs, defaults, or missed payments may face limited options or higher rates.
Age and Employment:
There is typically no upper age limit for company directors, but lenders may require directors to be between 21 and 85. Employment status is less critical, though self-employed directors should provide accounts or SA302s.
Portfolio Landlord Requirements:
If the director owns four or more mortgaged buy-to-let properties, they are considered a portfolio landlord. Additional documentation, such as a business plan and full portfolio spreadsheet, may be required (Read our guide to portfolio landlord mortgages).
Limited Company vs Personal Name:
Mortgages in a limited company name are assessed differently from personal name applications. The company must be an SPV with appropriate SIC codes. Personal guarantees are usually required from directors.
Compliance:
Landlords must meet right-to-rent checks, property licensing rules, and local authority regulations. Failure to comply may result in mortgage refusal or legal penalties.
Costs and Affordability
Limited company buy-to-let mortgages involve several costs beyond the deposit. These include:
– Arrangement fees: 1% to 2% of the loan amount
– Valuation fees: £300 to £1,000 depending on property value
– Legal fees: £1,000 to £2,000, often higher for limited company transactions
– Broker fees: £495 to £2,000 depending on complexity
Interest rates for limited company mortgages are generally 0.25% to 0.75% higher than personal name equivalents. Fixed-rate products offer stability, while variable or tracker rates may be cheaper initially but carry more risk.
Rental income must meet the lender’s ICR requirements, and affordability is stress-tested at higher notional rates to ensure sustainability even if interest rates rise.
Taxation plays a key role. Limited companies are not affected by Section 24, which restricts mortgage interest relief for individuals. Instead, mortgage interest is treated as a business expense, potentially reducing corporation tax liabilities (Read our guide to buy-to-let taxation).
Landlord insurance and buildings insurance are mandatory, and some lenders require rent guarantee cover.

Frequently Asked Questions
What deposit do I need for a limited company buy-to-let mortgage?
Most lenders require a minimum deposit of 25% for limited company buy-to-let mortgages. Some may ask for 30% or more, especially for new companies or non-standard properties. A higher deposit can improve your interest rate and increase your chances of approval. The deposit must usually come from personal savings or director loans, not from other borrowing.
Can I get a limited company buy to let mortgage beneficial ownership new company through a limited company?
Yes, you can. The mortgage is taken out in the name of a limited company, typically an SPV set up solely for property letting. The beneficial ownership lies with the directors and shareholders, who control the company and receive profits. Most lenders require personal guarantees from directors and assess the company’s structure and rental income.
What rental coverage do lenders require?
Lenders use an Interest Coverage Ratio (ICR) to assess rental affordability. For limited company mortgages, the typical requirement is 125% to 145% of the mortgage interest, stress-tested at 5.5% or higher. For example, if your monthly mortgage interest is £1,000, your rental income must be at least £1,250 to £1,450. Some lenders may use a lower stress rate for limited companies.
How does Section 24 tax affect buy-to-let mortgages?
Section 24 restricts individual landlords from deducting mortgage interest from rental income when calculating income tax. This can significantly increase tax liability. Limited companies are not affected by Section 24, as mortgage interest is treated as a business expense. This is one of the main reasons investors use limited company structures for buy-to-let properties.
Can I live in a property with a limited company buy-to-let mortgage?
No, you cannot live in a property financed with a limited company buy-to-let mortgage. These mortgages are strictly for rental purposes. Living in the property would breach the mortgage terms and could lead to repossession. If you wish to live in the property, you would need a residential mortgage, not a buy-to-let product.
