How to Secure a Mortgage Through Your Limited Company

More landlords are choosing to buy property through a limited company as part of a long-term investment strategy. While the benefits can be significant, the process of securing a limited company buy to let mortgage is different from applying in your personal name.

This guide focuses on the practical steps you need to take to successfully secure a mortgage through a limited company, from setting up the right structure to preparing your application and avoiding common mistakes.

If you want a detailed breakdown of what lenders assess, see our guide to limited company mortgage criteria.

What Is a Limited Company Buy to Let Mortgage?

A limited company buy to let mortgage is designed for properties owned by a company rather than an individual. In most cases, landlords use a Special Purpose Vehicle (SPV), a company set up solely to hold and let property.

Although the mortgage is taken in the company’s name, lenders still assess the directors personally and usually require personal guarantees.

Why Landlords Use Limited Companies

Limited company ownership is commonly used by landlords who want to:

• Deduct mortgage interest as a business expense
• Manage tax more efficiently at higher income levels
• Retain and reinvest profits to grow a portfolio
• Simplify ownership where multiple directors or shareholders are involved
• Support longer-term estate and succession planning

These benefits are often most relevant for portfolio landlords and higher-rate taxpayers.

Step 1: Set Up the Right Company Structure

Most lenders prefer a UK-registered SPV with no unrelated trading activity.

Before applying for a mortgage:

• Ensure the company is registered with appropriate property-related SIC codes
• Keep the ownership structure simple
• Confirm all directors and shareholders are correctly listed

If your company trades in other areas, lender choice may be more limited.

Step 2: Open a Business Bank Account

A dedicated company bank account is essential. It helps demonstrate clear separation between personal and business finances and allows lenders to see how funds are managed.

Deposit monies and rental income should flow through the company account wherever possible.

Step 3: Prepare Your Personal Finances

Even though the mortgage is in the company name, lenders assess directors individually.

Before applying:

• Check your personal credit file for errors
• Reduce unsecured debts where possible
• Ensure income and asset positions are clearly evidenced
• Be prepared to provide personal guarantees

Clean, well-documented personal finances can significantly improve lender confidence.

Step 4: Build the Deposit and Budget for Costs

Most limited company buy to let mortgages require a minimum 25 percent deposit.

In addition to the deposit, budget for:

• Stamp Duty Land Tax (including the additional property surcharge)
• Legal and valuation fees
• Broker and arrangement fees
• Initial refurbishment or compliance works

Planning these costs early helps avoid delays later in the process.

Step 5: Gather the Required Documents

Having paperwork ready speeds up the application process. Lenders typically request:

• Company incorporation documents
• Business bank statements
• Proof of deposit source
• Identification and address verification for directors
• Rental income projections or letting agent estimates

Newly formed SPVs are commonly accepted, provided directors meet personal requirements.

Step 6: Work With a Specialist Broker

Not all lenders offer limited company mortgages, and criteria vary widely.

• A specialist buy to let broker can:
• Match your company structure to suitable lenders
• Guide you through documentation and underwriting
• Handle complex cases such as first-time landlords or portfolio borrowers
• Secure an agreement in principle before you commit to a purchase

This is often the most efficient route to approval.

Step 7: Apply and Secure an Agreement in Principle

Once your application is prepared, the lender can issue an agreement in principle. This gives you confidence when making offers and demonstrates credibility to sellers and agents.

Common Mistakes to Avoid

• Using incorrect or missing SIC codes
• Assuming all lenders accept limited companies
• Underestimating total upfront costs
• Refusing to provide personal guarantees
• Applying before finances and documents are ready

Avoiding these issues can save weeks in the application process.

Is a Limited Company Mortgage Right for You?

Limited company mortgages are particularly suited to landlords who:

• Plan to grow or already own a portfolio
• Are higher or additional rate taxpayers
• Want flexibility to reinvest profits
• Prefer a structured, long-term investment approach

They do require more planning and higher upfront costs, but for many investors the benefits outweigh the complexity.
