However, seasoned companies with appropriate articles of association may access more competitive rates and lender flexibility. These mortgages are popular with portfolio landlords seeking tax advantages and long-term investment growth.
How This Mortgage Works
A limited company buy to let mortgage articles of association seasoned company is a loan secured against a rental property owned by a limited company, rather than an individual. The “seasoned” aspect refers to companies that have been incorporated and trading for at least 12 months, which many lenders prefer due to perceived stability and financial history. The articles of association must explicitly allow property letting and mortgage borrowing, or lenders may reject the application.
Mortgage types include fixed-rate (typically 2 to 5 years), variable, and tracker products. Fixed rates offer stability amid rising interest rates, while tracker products may suit investors expecting rate reductions. These mortgages are structured on an interest-only or capital repayment basis, though most landlords choose interest-only to maximise cash flow.
This mortgage type suits experienced landlords, portfolio investors, and those seeking to expand under a limited company structure. It differs from residential mortgages in that affordability is based on rental income rather than personal income, and the underwriting process involves both the company and its directors. Lenders assess the company’s financials, directors’ creditworthiness, and the property’s rental yield.
Eligibility and Criteria
To qualify for a limited company buy to let mortgage articles of association seasoned company, both the company and its directors must meet specific criteria set by lenders.
Income requirements: While personal income is not the primary factor, most lenders prefer directors to have a minimum income of £25,000 to £30,000. This demonstrates financial stability and helps in cases where rental income is borderline.
Rental coverage: Lenders use a rental stress test to ensure the property generates sufficient income. Typically, rental income must cover 125% to 145% of the mortgage payment, stressed at 5.5% or higher. For limited companies, the lower 125% threshold often applies due to the different tax treatment.
Property types: Standard buy-to-let properties such as single-family homes and flats are widely accepted. However, HMOs (houses in multiple occupation), new builds, and flats above commercial premises may face tighter criteria or higher interest rates.
Credit score: While there’s no fixed minimum, directors usually need a clean credit history with no recent defaults, CCJs, or bankruptcies. Some specialist lenders may consider adverse credit at higher rates.
Age and employment: Most lenders require directors to be aged 21 to 85 at the end of the mortgage term. Employment status is less critical than in residential lending, but self-employed directors may need to show business accounts.
Portfolio landlords: If the company owns multiple properties, lenders will assess the overall portfolio performance. This includes rental income, loan-to-value ratios, and exposure limits. Some lenders cap the number of mortgaged properties allowed.
Limited company structure: The company must be a Special Purpose Vehicle (SPV), typically with SIC code 68209 (letting and operating of own or leased real estate). The articles of association must permit property letting and borrowing. Non-SPV companies may face additional scrutiny.
Compliance: Landlords must meet right-to-rent checks, licensing requirements for HMOs, and local authority regulations. Lenders will not proceed if the property breaches legal requirements.
Costs and Affordability
Several costs are involved in securing a limited company buy-to-let mortgage:
– Arrangement fees: Typically 1% to 2% of the loan
– Valuation fees: £300 to £1,000 depending on property value
– Legal fees: £800 to £1,500 (limited company legal work is more complex)
– Broker fees: £500 to £1,000 (if using a specialist adviser)
Interest rates vary by lender and product type. Fixed rates offer certainty but may be higher than variable rates. In 2025, average BTL mortgage rates range from 4.5% to 6.5%.
Affordability is assessed based on rental income, not personal salary. Lenders apply a stress test to ensure the rent can cover mortgage payments even if rates rise. For limited companies, the stress rate is often lower than for individual landlords due to different tax treatment.
Taxation is a major factor. Limited companies are not affected by Section 24 mortgage interest relief restrictions, allowing full interest deduction as a business expense. However, corporation tax and dividend tax must be considered. Professional tax advice is essential.
Insurance requirements include buildings insurance and often landlord insurance covering liability, rent loss, and legal expenses.

4. Valuation: The lender arranges a property valuation to confirm market value and rental potential.

7. Completion: Funds are released, and the mortgage is secured against the property.
