Limited Company Buy To Let Mortgage

Buying buy-to-let property through a limited company has become increasingly popular with landlords and property investors looking for a more tax-efficient and flexible way to grow their portfolio. A limited company buy to let mortgage can offer long-term advantages — but the lending criteria, setup, and process are different from standard buy-to-let mortgages.

At Rosa Mortgages, we help investors secure the right limited company buy-to-let mortgage with clear, tailored advice. Whether you’re setting up a new SPV or already investing through a company, we’ll guide you through every step and match you with lenders that suit your strategy.

What Is a Limited Company Buy to Let Mortgage?

A limited company buy to let mortgage is a mortgage taken out by a limited company rather than an individual. The property is owned by the company, and the rental income is paid into the business rather than personally.

Most lenders prefer the company to be a Special Purpose Vehicle (SPV) — a limited company set up specifically for property investment. These companies usually have specific SIC codes related to property letting and management, which lenders favour.

Key differences compared to personal buy-to-let mortgages include:

  • The mortgage is in the company’s name, not yours personally
  • Rental income is assessed at company level
  • Directors are usually required to provide personal guarantees
  • Interest rates and fees may differ slightly from personal BTL products

Despite these differences, limited company buy-to-let mortgages are now widely available through both high-street and specialist lenders.

Why Buy Buy-to-Let Property Through a Limited Company?

Potential Tax Efficiency for Limited Company Buy To Let Mortgage 

One of the main reasons investors choose a limited company structure is tax efficiency. Rental profits are taxed under corporation tax rules, which may be lower than personal income tax for some landlords. In addition, mortgage interest can generally be treated as a business expense within the company. Tax treatment depends on individual circumstances — we always recommend speaking to a qualified tax adviser alongside mortgage advice.

Portfolio Growth & Reinvestment

A limited company structure can make it easier to retain profits within the business and reinvest them into future property purchases, helping investors grow portfolios more strategically.

Separation of Personal & Business Finances

Owning property through a company creates a clear distinction between your personal finances and your investment activity, which many landlords prefer from a planning and organisational perspective.

Professional Investment Strategy of a limited company buy to let mortgage

Limited company buy-to-let mortgages are often used by landlords who are serious about long-term investment, portfolio expansion, and structured financial planning.

Who Can Apply for a Limited Company Buy to Let Mortgage?

Limited company buy-to-let mortgages are available to a wide range of investors, including:

  • First-time landlords (with certain lenders)
  • Experienced landlords and portfolio investors
  • Directors and shareholders of UK-registered companies
  • Newly formed SPVs or existing limited companies

Most lenders will assess the directors personally, even though the mortgage is in the company’s name. This includes reviewing personal income, credit history, and experience.

Deposit Requirements & Borrowing Criteria for a Limited Company Buy To Let Mortgage

When applying for a limited company buy to let mortgage, lenders typically look at the following:

✓
Deposit Levels

Most lenders require a deposit of 20–25%, although some may ask for more depending on the property type, rental yield, or investor profile.

✓
Loan-to-Value (LTV)

Company buy-to-let mortgages usually cap borrowing at 75–80% LTV, though this varies by lender.

✓
Rental Coverage (ICR)

Lenders assess whether the rental income sufficiently covers the mortgage payments, often using a stress-tested interest rate.

✓
Personal Guarantees

Almost all lenders require directors/shareholders to provide personal guarantees, meaning you remain personally responsible if the company cannot meet repayments.

Can You Get a Limited Company Buy to Let Mortgage with Bad Credit?

It may still be possible to secure a limited company buy to let mortgage with past credit issues, depending on:

  • The type and age of the credit problem
  • Whether issues are now satisfied
  • Your overall financial position
  • The strength of the rental income and deposit

Specialist lenders may be more flexible on credit history, particularly where the investment makes sense and affordability is strong. At Rosa Mortgages, we’ll assess your situation honestly and guide you towards realistic options.

  • How much deposit do I need?

    Most lenders require at least 20–25%, though this can vary depending on the property and rental income.

  • Will an IVA stop me from buying a home?

    No. It may limit your options, but specialist IVA mortgage lenders regularly approve applications from people with past IVAs.
