Limited company buy to let mortgage basic rate taxpayer capital repayment is a specialist type of landlord mortgage designed for property investors who purchase rental properties through a limited company structure. This mortgage type is increasingly popular among basic rate taxpayers seeking capital repayment options, as it offers potential tax efficiencies and long-term investment benefits. With rising interest in buy-to-let lending and changes to taxation rules in recent years, many landlords are choosing to operate via limited companies to mitigate the impact of Section 24 and maximise returns on investment property finance.
In 2025, limited company buy-to-let mortgages remain a strategic choice for landlords who want to build or expand their portfolios while repaying both interest and capital. This approach helps reduce outstanding debt over time and can improve affordability assessments for future borrowing. Despite higher interest rates compared to personal name mortgages, the ability to offset mortgage interest against rental income within a limited company structure remains a compelling advantage for many investors.

How This Mortgage Works
A limited company buy to let mortgage basic rate taxpayer capital repayment works by allowing landlords to purchase or refinance rental properties through a special purpose vehicle (SPV) limited company. Unlike interest-only products, capital repayment mortgages require monthly payments that cover both interest and a portion of the loan principal, gradually reducing the outstanding balance over time.
These mortgages are available in various product types, including fixed-rate deals (2, 5, or 10 years), variable rates, and tracker options. Fixed-rate products are popular in 2025 due to ongoing interest rate fluctuations, providing certainty over monthly repayments.
This mortgage type suits a range of investors, from first-time landlords to experienced portfolio landlords. Basic rate taxpayers benefit from the ability to offset mortgage interest against rental income within the company, which is no longer possible for personal name landlords due to Section 24 restrictions.
Lenders assess limited company applications differently from standard residential mortgages. They focus on the property’s rental income and the company’s financials rather than the applicant’s personal income. Borrowing is typically based on rental coverage ratios and stress-tested interest rates, rather than salary multiples.
Eligibility and Criteria
To qualify for a limited company buy to let mortgage basic rate taxpayer capital repayment, applicants must meet specific lender criteria. While personal income is less critical than in residential lending, lenders still assess overall financial stability and experience.
– Income Requirements: While personal income is not the primary factor, some lenders may require a minimum personal income of £25,000 to £30,000 to ensure financial stability. Others may accept lower income if the rental property generates sufficient income.
– Rental Coverage: Affordability is assessed using rental coverage ratios, typically 125% to 145% of the mortgage payment, stress-tested at 5.5% to 6.5%. For capital repayment mortgages, the stress test includes both interest and capital portions, making affordability tighter than interest-only options.
– Property Type: Most lenders prefer standard buy-to-let properties such as single-family homes and flats. HMOs (houses in multiple occupation), holiday lets, and new builds may be accepted by specialist lenders but often come with stricter criteria and lower LTVs.
– Credit Score: A good credit history is essential. While there is no fixed score, applicants should ideally have no recent defaults, CCJs, or missed payments. Some adverse credit may be accepted by specialist lenders at higher rates.
– Age and Employment: Most lenders require applicants to be aged 21 to 85 at the end of the mortgage term. Both employed and self-employed applicants are accepted, provided the company structure is appropriate.
– Portfolio Landlords: Those with four or more mortgaged properties are considered portfolio landlords and must provide detailed information on their entire portfolio, including rental income, mortgage balances, and property values. (Read our guide to portfolio landlord mortgages)
– Limited Company Structure: The company must be an SPV (Special Purpose Vehicle), typically registered under SIC codes such as 68100 (buying and selling of own real estate). Trading companies are less commonly accepted.
– Licensing and Compliance: Properties must meet local authority licensing requirements, especially for HMOs. Right-to-rent checks must be completed for all tenants in England, and landlords must comply with EPC regulations (minimum rating of E, rising to C in 2028).
Costs and Affordability
When taking out a limited company buy to let mortgage basic rate taxpayer capital repayment, landlords should budget for several upfront and ongoing costs:
– Arrangement Fees: Typically 1% to 2% of the loan, or fixed fees from £995 to £2,000
– Valuation Fees: £300 to £800 depending on property value
– Legal Fees: £1,000 to £2,000 for limited company conveyancing
– Broker Fees: £495 to £1,500 depending on complexity
Interest rates for capital repayment products are generally higher than interest-only equivalents due to the increased risk to lenders. Fixed rates offer stability, while variable and tracker rates may be lower initially but carry the risk of rising costs.
Rental income is assessed using stress-tested calculations. For example, a property generating £1,200 monthly rent may support a loan of around £180,000, depending on the stress rate and rental coverage ratio.
Taxation is a key consideration. Limited companies can offset mortgage interest as a business expense, unlike personal name landlords affected by Section 24. However, corporation tax, dividend tax, and accountancy fees must also be factored in.
Landlords must also arrange appropriate insurance, including buildings insurance and landlord liability cover. Some lenders require rent guarantee insurance as part of affordability assessments.
The Application Process
Applying for a limited company buy to let mortgage basic rate taxpayer capital repayment involves several key steps:
1. Research: Identify suitable lenders and products with the help of a mortgage broker specialising in limited company BTL.
2. Company Setup: Ensure your SPV limited company is correctly registered with appropriate SIC codes.
3. Documentation: Prepare company accounts, proof of identity, proof of deposit, rental income projections, and property details.
4. Application Submission: Your broker submits the full mortgage application to the chosen lender.
5. Valuation: The lender arranges a valuation to confirm the property’s market value and rental potential.
6. Underwriting: The lender assesses the application, including affordability, credit checks, and company structure.
7. Legal Work: Solicitors carry out conveyancing, company checks, and mortgage deed preparation.
8. Completion: Funds are released, and the mortgage completes.
The process typically takes 4 to 8 weeks. Working with a broker increases the chance of approval, especially for complex or portfolio cases. Direct applications may be rejected due to missing documents or incorrect company setup.
Common reasons for rejection include insufficient rental income, poor credit history, incorrect SIC codes, or non-compliant properties. A broker can help pre-screen applications to avoid these pitfalls.
