Limited company buy to let mortgage articles of association capital repayment is a specialist mortgage product designed for landlords purchasing or remortgaging investment properties through a limited company structure. Unlike interest-only options, capital repayment mortgages require monthly payments that cover both interest and a portion of the loan principal, gradually reducing the debt over time. Landlords often choose this route to build equity and reduce long-term borrowing costs.
In 2025, this type of buy-to-let lending is gaining popularity due to tax advantages associated with limited companies and growing lender support for corporate structures. With rising interest rates and tightening affordability criteria, landlords are increasingly seeking structured finance solutions that align with their long-term investment goals. This mortgage type is particularly relevant for portfolio landlords, those affected by Section 24 tax changes, and investors aiming to retain profits within a company for reinvestment. Understanding the role of articles of association is crucial, as these govern how the company operates and must align with lender requirements.

Limited company buy-to-let mortgages with capital repayment are increasingly accessible, with more lenders entering the market. However, borrowers must meet stricter affordability and documentation requirements, including submitting appropriate articles of association and demonstrating sufficient rental income to meet stress-tested repayment thresholds.
How This Mortgage Works
A limited company buy to let mortgage articles of association capital repayment works by allowing a landlord to purchase or refinance an investment property through a special purpose vehicle (SPV) limited company. The mortgage is structured on a capital repayment basis, meaning each monthly payment reduces the loan balance while also covering interest charges.
These mortgages are typically offered with fixed, variable, or tracker interest rates. Fixed-rate products offer stability over 2, 5, or even 10 years, while variable and tracker rates fluctuate with the Bank of England base rate. Lenders assess affordability based on projected rental income, not personal income, although directors’ financial standing is still considered.
This mortgage type suits experienced or portfolio landlords, as well as first-time investors seeking tax efficiency through a limited company. It is particularly beneficial for those planning to hold properties long-term and reduce debt over time. Articles of association must be SPV-compliant, often referencing SIC code 68209 (letting and operating of own or leased real estate).
Compared to standard residential mortgages, these products involve stricter underwriting, higher stress testing, and more complex legal structures. However, they offer greater flexibility in tax planning, especially for higher-rate taxpayers.
Eligibility and Criteria
Lenders apply specific eligibility criteria when assessing limited company buy to let mortgage articles of association capital repayment applications. While personal income is not always a primary factor, most lenders require directors to have a minimum income of £25,000 to £30,000 for background affordability checks. Some specialist lenders may waive this for experienced landlords.
Rental income is the cornerstone of affordability. Lenders typically require the rental coverage ratio to be between 125% and 145% of the monthly mortgage payment, calculated at a stress-tested interest rate (often 5.5% to 6.5%). For capital repayment mortgages, this stress test is more stringent than for interest-only products.
Property type also affects eligibility. Standard buy-to-let properties such as single-family homes and flats are generally accepted. However, HMOs (houses in multiple occupation), new builds, and ex-local authority properties may have restrictions or require specialist lenders.
Credit history is important. Most lenders expect a clean credit file, although minor issues may be acceptable with higher deposits. A credit score of 650+ is usually required, but criteria vary.
Age limits typically range from 21 to 85, with some lenders capping the age at the end of the mortgage term. Employment status matters less than rental income, but self-employed applicants must provide company accounts and tax returns.
Portfolio landlords (those with four or more properties) face additional scrutiny. Lenders assess the entire portfolio’s performance, including rental yields, loan-to-value ratios, and overall leverage. They may also require a business plan or cash flow forecast.
Applications made through a limited company must use an SPV structure with appropriate articles of association. These must be aligned with lender requirements and detail the company’s purpose as property letting. Non-SPV companies or those with unrelated trading activity may face rejection.
Compliance with right-to-rent regulations and local licensing (such as selective licensing or HMO licensing) is mandatory. Failure to comply can result in mortgage refusal or legal penalties.
Costs and Affordability
Several costs are associated with a limited company buy to let mortgage articles of association capital repayment. Arrangement fees typically range from 1% to 2% of the loan amount, often added to the mortgage. Valuation fees vary by property value, starting from £300. Legal fees are higher than for residential purchases due to the corporate structure, usually £1,000 to £2,000.
Broker fees may apply, especially when using specialist brokers with access to niche lenders. However, brokers can help secure better BTL mortgage rates and ensure the articles of association meet lender criteria.
Interest rates for capital repayment buy-to-let mortgages are generally higher than interest-only options. Fixed rates in 2025 range from 5.2% to 6.8%, depending on LTV, property type, and borrower profile.
Rental income must comfortably cover mortgage repayments. Lenders apply stress tests to ensure affordability even if rates rise. For example, a loan stressed at 6.5% with 145% rental coverage means the monthly rent must be significantly higher than the mortgage payment.
Taxation is a key factor. Limited companies are not affected by Section 24 restrictions, allowing full mortgage interest relief. However, corporation tax applies to profits, and extracting income via dividends can incur personal tax.
Landlords must also budget for insurance, including buildings and landlord insurance, which is often a lender requirement.
The Application Process
Applying for a limited company buy to let mortgage articles of association capital repayment involves several key steps:
1. Research lenders and products – Compare mortgage rates, criteria, and terms. Consider using a broker for access to specialist lenders.

5. Property valuation – A surveyor will assess the property to confirm its value and rental potential.
6. Legal process – Solicitors handle the legal checks, including reviewing the company structure and property title.
7. Mortgage offer and completion – Once approved, you’ll receive a formal offer. Completion typically occurs within 4 to 8 weeks.
Working with a mortgage broker is highly recommended. They can help tailor your application, ensure compliance with lender criteria, and avoid common pitfalls such as unsuitable articles of association or insufficient rental coverage.
Common reasons for rejection include poor credit history, inadequate rental income, non-SPV company structure, or non-compliant property types.
Benefits, Risks and Alternatives
The main benefit of a limited company buy to let mortgage articles of association capital repayment is long-term debt reduction. By repaying capital monthly, landlords build equity and reduce exposure to future interest rate rises. Using a limited company also offers tax advantages, including full mortgage interest relief and potential inheritance tax planning benefits.
However, there are risks. Capital repayment mortgages have higher monthly costs, which may strain cash flow during void periods. Rising interest rates can impact affordability, and regulatory changes—such as EPC requirements—may affect property viability.
Alternatives include interest-only buy-to-let mortgages, which offer lower monthly payments but no capital reduction. Bridging loans or commercial mortgages may suit more complex projects. Development finance is another option for refurbishment or new-build schemes.
Remortgaging can be used to switch to a better rate or release equity. Product transfers may be quicker but offer less flexibility. Always compare both options based on your long-term goals.
