Limited company buy-to-let mortgages through an SPV are subject to different underwriting criteria than personal buy-to-let loans. Lenders assess rental income, affordability, and company structure, with many preferring SPVs registered with SIC code 68209. While interest rates can be slightly higher than personal BTLs, the tax advantages often outweigh the cost for basic rate taxpayers planning long-term property investment.
How This Mortgage Works
A limited company buy to let mortgage basic rate taxpayer SPV is a type of landlord mortgage specifically designed for properties owned by a limited company set up solely for property letting. These companies are known as Special Purpose Vehicles (SPVs) and are typically registered with HMRC using a relevant SIC code, such as 68209 (Letting and operating of own or leased real estate).
This mortgage allows basic rate taxpayers to purchase or remortgage investment properties through their SPV, separating personal finances from their property business. Lenders assess the company’s rental income rather than the applicant’s personal income, though directors’ financial backgrounds are still reviewed.
Product types include fixed-rate mortgages (usually 2-5 years), variable rates, and tracker deals. Fixed rates are currently popular due to interest rate volatility in 2025. Many lenders now cater to limited company applicants, including specialist BTL lenders and some high street banks.
This mortgage suits first-time landlords setting up a property business, experienced portfolio landlords seeking tax efficiency, and investors planning to grow their portfolio under a corporate structure. It differs from standard residential mortgages in that affordability is based on rental income, not personal income, and the property must not be owner-occupied.
Eligibility and Criteria
To qualify for a limited company buy to let mortgage basic rate taxpayer SPV, applicants must meet both personal and company-related criteria set by lenders. While the mortgage is in the name of the SPV, lenders still assess the directors and shareholders.
Income requirements are generally more flexible than personal BTL mortgages. Basic rate taxpayers may not need to show high personal income, as affordability is primarily based on rental income. However, lenders will typically require directors to have no adverse credit and demonstrate financial stability.
Rental coverage is a key factor. Most lenders require the projected rental income to cover 125% to 145% of the mortgage payment, stress-tested at an interest rate of 5.5% to 7.5%, depending on the product. This ensures the property can generate sufficient income even if rates rise.
Property types must usually be standard buy-to-let units. Some lenders avoid non-standard constructions, HMOs, or flats above commercial premises unless the applicant has experience and the property meets specific criteria.
Credit score expectations vary, but a clean credit history is preferred. Minor issues may be acceptable with some specialist lenders.
Age limits typically range from 21 to 85 at the end of the mortgage term. Employment status is less critical, but self-employed directors may need to show personal tax returns or company accounts.
Portfolio landlords must disclose all properties owned, including those held personally or in other companies. Some lenders limit the number of properties or total borrowing, while others specialise in complex portfolios (Read our guide to portfolio landlord mortgages).
Applications must be made through a limited company, not in a personal name. Most lenders prefer SPVs with no trading history and a clear purpose of property letting. Right-to-rent compliance, selective licensing, and local authority regulations must also be met, especially in England and Wales.
Costs and Affordability
Limited company buy to let mortgages come with several associated costs. Arrangement fees typically range from 1% to 2% of the loan amount and may be added to the mortgage. Valuation fees vary based on property type and value, while legal fees are often higher than for personal mortgages due to the corporate structure.
Interest rates for limited company BTLs are slightly higher than for personal BTLs, averaging between 4.5% and 6.5% in 2025. Fixed-rate deals offer stability, while variable and tracker rates may be cheaper initially but carry more risk.
Rental income is the primary affordability metric. Lenders use rental coverage ratios and stress testing to ensure the property generates sufficient income. For example, a £1,000 monthly rent might need to cover a notional mortgage payment of £800 at a stressed rate, requiring a 125% coverage.
Taxation is a key driver for using an SPV. Since the introduction of Section 24, individual landlords can no longer deduct full mortgage interest from rental income. Limited companies, however, can deduct mortgage interest as a business expense, making this structure more tax-efficient for many investors.
Landlords must also budget for insurance, including buildings and specialist landlord insurance, which is often a lender requirement. Stress testing at higher rates means affordability must be robust even in rising rate environments.
The Application Process
Applying for a limited company buy to let mortgage basic rate taxpayer SPV involves several steps, from initial research to completion. Working with a specialist mortgage broker can streamline the process and improve approval chances.
Step 1: Set up an SPV limited company with the correct SIC code (e.g. 68209). Ensure all directors and shareholders are listed.
Step 2: Research mortgage products or consult a broker to find suitable lenders and rates. Consider fixed vs variable rates based on your risk appetite.
Step 3: Prepare documentation, including proof of identity, proof of address, business bank statements, projected rental income, and property details. Directors may also need to provide SA302s or tax returns.
Step 4: Submit the application. The lender will assess the company structure, rental income, and director backgrounds.
Step 5: The lender instructs a valuation and may require a survey. This confirms the property’s rental potential and condition.
Step 6: Legal work begins. Solicitors handle company checks, property title, and mortgage deed.
Step 7: On approval, funds are released and the mortgage completes.
Applications typically take 4 to 8 weeks. Common reasons for rejection include incorrect SIC codes, insufficient rental income, poor credit history, or non-compliant property types. Using a broker can help avoid these pitfalls and match you with the right lender.
Benefits, Risks and Alternatives
Limited company buy to let mortgages offer several benefits for property investors. For basic rate taxpayers, they provide a way to plan for future tax changes, retain mortgage interest relief, and separate personal and business finances. They also allow easier profit retention within the company for reinvestment.
Risks include higher interest rates, more complex legal and accounting requirements, and potential regulation changes. Void periods or rising interest rates can affect cash flow, and lenders may be more cautious with corporate structures.
Alternatives include bridging loans for short-term finance, commercial mortgages for mixed-use properties, or development finance for refurbishment projects. These may suit different investment strategies.
When remortgaging, landlords can choose between switching lenders or opting for a product transfer. A remortgage may offer better rates, while a product transfer can be quicker and cheaper but may lack flexibility.
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 depending on the property type, location, and rental income. A higher deposit can improve your chances of approval and may unlock better interest rates.
Can I get a limited company buy to let mortgage basic rate taxpayer SPV through a limited company?
Yes, this mortgage type is specifically designed for SPV limited companies. As a basic rate taxpayer, you can benefit from tax efficiencies by purchasing or remortgaging rental properties through a company structure. Ensure your company is correctly registered with an appropriate SIC code and has no unrelated trading activity.
What rental coverage do lenders require?
Lenders typically require rental income to cover 125% to 145% of the mortgage payment, stress-tested at an assumed interest rate (often 5.5% to 7.5%). This ensures the property can generate enough income to cover the mortgage, even if rates rise. The exact coverage ratio depends on the lender and product type.
How does Section 24 tax affect buy-to-let mortgages?
Section 24 restricts individual landlords from deducting full mortgage interest from rental income, increasing their tax liability. Limited companies are not affected by Section 24 and can treat mortgage interest as a business expense. This makes limited company mortgages more attractive for many landlords, even basic rate taxpayers planning long-term.
Can I live in a property with a limited company buy to let mortgage basic rate taxpayer SPV?
No, you cannot live in a property financed with a limited company buy-to-let mortgage. These mortgages are strictly for investment purposes, and lenders prohibit owner-occupation. Living in the property would breach the mortgage terms and could lead to repossession or legal action.
